#1: NGK vs Bosch spark plugs Author: Johnbyron, Location: ScunthorpePosted: Mon Jul 09, 2012 1:42 pm ---- What's this about Bosch being better than NGK ??
I went into halfords and had a look through the little books and bosch only list spark plugs for the gti 2.0 but the engine codes state just the 137 engine and doesn't mention the 180 engine code, so I looked in the NGK book and they stated the 137 engine and 180 engine separately, the NGK spark plugs for the 137 have a heat rating of 5 and the 180 has a heat rating of 6 so that show you shouldn't use the bosh in the 180 surely ???
#2: Re: NGK vs Bosch spark plugs Author: DeadEyePaul, Location: Rugby,WarwickshirePosted: Mon Jul 09, 2012 1:44 pm ---- Peugeot coil packs do not like NGK
#3: Re: NGK vs Bosch spark plugs Author: MrBSI, Location: What's it to you? ? ?Posted: Mon Jul 09, 2012 1:44 pm ---- NGK spark plugs + 206 = possible misfires, loss of power & electrical problems.
Its been covered to death on here over the years.
Fit the correct Bosch plugs for the engine in question on a 206.
Use the Bosch automotive website to find the correct spark plug info.
#4: Re: NGK vs Bosch spark plugs Author: Johnbyron, Location: ScunthorpePosted: Mon Jul 09, 2012 1:46 pm ---- But NGK have been on the go for donkey years !! I can't understand what's different , a plug is a plug and Bosch don't specify a plug for the 180
#5: Re: NGK vs Bosch spark plugs Author: Seabook, Posted: Mon Jul 09, 2012 1:47 pm ---- i use NGK plug and it gave me at least 10% power gain
#6: Re: NGK vs Bosch spark plugs Author: tagget, Location: southamptonPosted: Mon Jul 09, 2012 1:48 pm ---- Im not sure but since i had my Service i think they installed (NGK) havent asked yet but been having a few problems... Bogging out small black smoke running rich... Idle going from 1k to 5K without placing my foot on the accelerator then stops when warm.. but changing to bosch soon once Lambda sensor and ICV Sensor has been changed..

Its been covered to death on here, just do what you want.
Bosch do make a spark plug for the GTI 180 engine if you bother to look.
#11: Re: NGK vs Bosch spark plugs Author: MrBSI, Location: What's it to you? ? ?Posted: Mon Jul 09, 2012 1:54 pm ---- Bosch also do another 2 different spark plugs for GTI 180 engines running on LPG / CNG.
So Bosch list 3 different spark plugs for the GTI 180 lump depending on what fuel its run on.
i use NGK plug and it gave me at least 10% power gain
Were there the NGK Glow+ ones?
that was a bad joke
Shush
#15: Re: NGK vs Bosch spark plugs Author: Johnbyron, Location: ScunthorpePosted: Mon Jul 09, 2012 2:00 pm ---- I have fitted them and no problems what so ever!! Sure it may run slightly lumpier when cold but who cares I'd tater that than them melt because they can't cope with the heat,
Yeah iv just looked but what's the super 4 code for the 180 engine then because it isn't supposed to be the same as the 137 that's for sure.
What's this code for then?? (what make plug??) FQR7ME
True halfords are a bit pants for parts haha

I couldnt care less, fit the wrong spark plugs & as your mate has found out its caused damage to the engine.
Waste of time Bosch having a free technical website for people to use aint it
I did post the link on page 1 of this thread.
#22: Re: NGK vs Bosch spark plugs Author: Johnbyron, Location: ScunthorpePosted: Mon Jul 09, 2012 2:24 pm ---- I used the link and it didn't give me a code for the gti 180 spark plugs (although I am on my iPhone and sometimes it doesn't show stuff up)
Anyway cars arn't built to run certain makes of plugs they are made to run certain specs of plugs I thought you'd of been smart enough to know that mr BSI on every bike I've built I've set them up to run NGK platinum plugs because they were the longest lasting and can cope with the heat I was putting on them (12 heat) if the 180 is supposed to run 7's then mine was wrong in the first place because when I replaced mine the old ones were 5 and I never had any trouble but the ends did look a bit warped and my mates is running funny so five are obveously a big no no !!
#23: Re: NGK vs Bosch spark plugs Author: spike_202, Location: West midsPosted: Mon Jul 09, 2012 2:45 pm ---- I use bosh super 4s, replace them once a year usually when I do a full service

Stick the NGK plugs in then & see what happens if you think you know better
Im smart enough to follow the technical advice of PSA Peugeot / Citroen & not fit NGK spark plugs to one of there products due to the incompatibility NGK plugs cause with the coil packs phase detection system
Im also smart enough to put the correct heat range spark plug in the engine as recommended by both PSA Peugeot / Citroen & the spark plug manufacturer Bosch.
You aint gonna listen to sense so just do what you want.
#26: Re: NGK vs Bosch spark plugs Author: Johnbyron, Location: ScunthorpePosted: Mon Jul 09, 2012 2:53 pm ---- Because in halfords the Bosch super fours wern't listed for the 180 they where only listed for the 137 engine I double checked the engine codes

#28: Re: NGK vs Bosch spark plugs Author: spike_202, Location: West midsPosted: Mon Jul 09, 2012 2:57 pm ---- Sony get the 4s then get standard bosh they are just as good I took my ngk out when I 1st had my pug as it felt hesitant and juddery then did a service and put bosh in and was fine.
#29: Re: NGK vs Bosch spark plugs Author: Johnbyron, Location: ScunthorpePosted: Mon Jul 09, 2012 2:58 pm ---- Where do you get your information from mr BSI ?? How do you know NGK arnt to be used ?? I'm not saying your wrong I'm just wanting some clarification and yeah thatS the reason I didn't buy the super fours from halfords, because I know the 180 will need a higher heat rating than the 137, but I just thought it might be only one higher, turns out bosh recommend two hisher than the 5's
#30: Re: NGK vs Bosch spark plugs Author: Johnbyron, Location: ScunthorpePosted: Mon Jul 09, 2012 3:02 pm ---- Okay I'll buy some fours and compare the two Over 6k miles each set just to satisfy people like myself

Has no one tried Denso plugs?
Heat range Bosch say 7 NGK 6.

People on here will know a lot of stuff that's why I ask things!! I don't question them all the time it just seems like on this subject it's a bit of a myth and ngk's havnt been proven to be any better than bosch and you may think I'm some 19 old Chav that sits in mc Donalds car park but the truth is I'm an apprentice mechanical engineer currently studying HNC/HND in mechanical engineering and I'll be moving on to do my finall degree in mechanical engineering in another two years, so if you think you can teach me more about technical mechanical workings than a number of lecturers plus all the engineers I work with then fair enough that's you thoughts but please don't try and big yourself up to me, I work with the best in my profession that's who I'll not question.

Yeah :-/ that's why I didn't buy the Bosch super fours from halfords because 5 seemed a bit low and NGK had recommended 6 so I got the NGK because I trust them but I thought id ask about it just incase

Heat range Bosch say 7 NGK 6.
I had exactly the same thing with a few of my 2strokes, at cadwel park the lads use NGK 90% of the time.
I never tried denso plugs but my uncle uses them in some of his bike but mainly he sticks with NGK partially due to supply he says they're just as good and hasn't had problems.
#42: Re: NGK vs Bosch spark plugs Author: V9977, Location: Athens, GreecePosted: Tue Jul 10, 2012 12:31 am ---- All modern spark-plugs include an anti-parasitic resistor in series with the center electrode.
It is this resistor (not tightly specified by manufacturers) which can sometimes cause havoc
with NGK plugs and pug coilpacks / ECU. There have been numerous Info-flash issued
by Peugeot themselves about this and is deffo not a myth.
It is also deadly important to fit the part-code explicitly specified by the plug manufacturer for your engine.
Not enough to compare heat-range, thread size and length.
NGK are OEM λ-probes for the 206 so no-one is dissing the brand.
Imo if you ask on here, you will get people's advice/past experience even if you choose to
bear it in-mind, but actually ignore it. Otherwise why ask?
P.S. Anyone ever wondered why there is only 4 wires going to the coil-pack,
when 1 wire is earth but there is 4 spark-plugs?

Thank you for coming up with some explanation that all I wanted why should I just believe somebody that just puts 206+NGK=faults or whatever?? I wanted information on why not for somebody just to say NGK don't mix with 206 because when you put it like that it just sounds stupid and I'd be stupid to listen to it without information On why
#44: Re: NGK vs Bosch spark plugs Author: tomd0801754, Location: MoscowPosted: Tue Jul 10, 2012 1:27 am ---- If only all those threads were around from 3-4years ago...
Iirc, it was a Peugeot 'Technical update thingy', sent to all dealerships/approved garages etc. that Bosch plugs should only be used.
Btw: Just because someone is a lecturer it doesn't mean that they are 'the best' in the field/business. Plus I'm sure a few more on here know more about specific 206 issues than some of your lecturers.
#45: Re: NGK vs Bosch spark plugs Author: Johnbyron, Location: ScunthorpePosted: Tue Jul 10, 2012 1:41 am ---- Yes Tom I wish try were two because I like to read up on why things are how they are, and fair enough about the lecturers but what about the engineers on the steelwork where I am they all have their papers and the majority have around 35+ years experience in mechanical engineering and you can't just put it down to magic the fact the 206's don't run well on NGK there must be logic

No, my point is how can they have any problems to report on NKG plugs in a 180 when if they replace them they will replace them with the standard plugs it came out of the factory with.
Either way mate I no longer care.
#54: Re: NGK vs Bosch spark plugs Author: V9977, Location: Athens, GreecePosted: Wed Jul 11, 2012 2:56 am ---- All Peugeot vehicles come from the factory with Eyquem spark-plugs (French) which cost a fair bit.
Dealerships are supposed to fit those only.
There have been Info-flash issued by Peugeot regarding NGK plugs, full stop/end of story.
#55: Re: NGK vs Bosch spark plugs Author: Johnbyron, Location: ScunthorpePosted: Wed Jul 11, 2012 3:53 am ---- Right okay I've done my research now and I am intrigued to find out what the difference is between the recommended NGK plug, the recommended Bosch plug from Peugeot and the Bosch super four from halfords. So this is what I'll do next week,
I'll buy one of each spark plug and dismantle each one,
I'll take measurements for each dimension including the thickness using a micrometer and a vernier,
I'll take a photo of them all dismantled placed side by side and I will list the measurement and then we can all se what the difference Is bettween the plugs, I'll also double-check what materials are used for each one. This will allow me to see if anything could cause the NGK to interfere with the coil pack.
If I'm wrong about all this I will gladly apologise for wasting everybody's time.
#56: Re: NGK vs Bosch spark plugs Author: 206boyracer, Location: Sunny CornwallPosted: Wed Jul 11, 2012 4:10 am ---- I'd be curious to see the difference. I'm also confused how simply a different brand can mess with the car. Not saying it doesnt before anyone shoots me down. Just curios how.
#57: Re: NGK vs Bosch spark plugs Author: macca1411, Location: Westhoughton, LancashirePosted: Wed Jul 11, 2012 4:30 am ---- It might not be anything to do with the physical appearance of the plug.
I would be more concerned with how long it takes to pass 40,000 volts down the electrode and how strong the spark is at the end.
It might even be to do with the wasted spark on the exhaust stroke or the ECU receiving the wrong information which will either advance or retard the engine timing to allow for this error which in turn will have an effect on the running of the engine.
#58: Re: NGK vs Bosch spark plugs Author: Johnbyron, Location: ScunthorpePosted: Wed Jul 11, 2012 5:09 am ---- Macca let's not say any more and let the results speak for themselves and the length of the different sections within the spark plug that determine how long it takes for the plug to pass 40,000 volts (aslong as they are the same material which the majority are), it's not magic it's engineering, if all plugs have the same material and the same specification they will have the same effect as each other (obviously you have to take into account product tolerances so not every spark plug will be exactly the same but they will still work within the tolerance)

That is plain irrelevant/incorrect.
Mate, testing and evaluation of such a component is not play-time.
The materials used (thermal characteristic of centre electrode, body, insulator to name but a few) would take serious equipment to make valid conclusions not simply take picy's of them.
What about measuring the (anti-parasitic) resistor between the top node and centre electrode? This would likely be different for every plug and could change when High Tension Voltages are involved. So you measure with your multimeter which uses a couple of volts to take the measurement, then in HT context it totaly changes behaviour due to other factors coming into play.
Studying how and when the arc (spark) happens has a stupendous amount of theory and practice involved. Long-term effects and reliability, even more so.
P.S. Super-4 are not specified by BOSCH for any 206 engine.
When people put them in, the ones that do fit have a different gap.
@Macca respect to you Sir for knowing why there is only 4 wires going to the coil-pack, (wasted spark, 2 plugs firing together).

#63: Re: NGK vs Bosch spark plugs Author: V9977, Location: Athens, GreecePosted: Wed Jul 11, 2012 6:23 am ---- No two sparking plugs are the same spec. Too many variables.
That's the point and that's why NGK are avoided in this context.
It doesn't mean that there will definately be a cockup, but it could cause problems later-on.
Better to have less things to worry about when the inevitable time comes your pugy will have a complaint.

So are you saying that NGK arnt as good as Bosch because they have slack tolerances ??

Nope.
As I understand there is a problem with them and some coil-pack/ECU in pugs.
NGK is a top brand and is used for λamda sensors by Peugeot, from the factory.
#66: Re: NGK vs Bosch spark plugs Author: Johnbyron, Location: ScunthorpePosted: Wed Jul 11, 2012 6:46 am ---- Right okay good, but why do people say that NGK plugs should not be used in 206's full stop ?? If it's certain 206 models that don't like NGK why don't we say that not just say no 206 should run ngk's. So just to clarify my mate that is running Bosch super fours in his 180 could have got a problem with his coil pack due to the fact super fours are not recommended for the 206 gti 180 ??
#67: Re: NGK vs Bosch spark plugs Author: DJKaySee, Location: UK, England,NottinghamPosted: Wed Jul 11, 2012 6:46 am ---- I have spent ages looking through every post of on this thread and from what I have seen I will be sticking with Bosch plugs, as its what a lot of well trusted people on here recommend, I have also learned quite a bit from this :-D.

To be fair I would have gone for standard Bosch plugs if I had any reason to doubt NGK but I don't so I got NGK , on the other hand l have seen posts on other threads recommend Bosch super fours for a gti 180 when actually Bosch super fours arnt even supposed to go in a gti 180 so I'm glad I didn't take any notice of halfrauds

All modern spark-plugs include an anti-parasitic resistor in series with the center electrode.
It is this resistor (not tightly specified by manufacturers) which can sometimes cause havoc
with NGK plugs and pug coilpacks / ECU. There have been numerous Info-flash issued
by Peugeot themselves about this and is deffo not a myth.
It is also deadly important to fit the part-code explicitly specified by the plug manufacturer for your engine.
Not enough to compare heat-range, thread size and length.
NGK are OEM λ-probes for the 206 so no-one is dissing the brand.
Imo if you ask on here, you will get people's advice/past experience even if you choose to
bear it in-mind, but actually ignore it. Otherwise why ask?
P.S. Anyone ever wondered why there is only 4 wires going to the coil-pack,
when 1 wire is earth but there is 4 spark-plugs?
#70: Re: NGK vs Bosch spark plugs Author: Johnbyron, Location: ScunthorpePosted: Wed Jul 11, 2012 7:03 am ---- Sorry I typed that wrong I don't mean why is it that Ngk plugs mess with pug coil packs I'm asking why people on here slate NGK and tell people to use Bosch super four when actually that's just as bad as using NGK because NGK doesn't mess with all coil packs on 206's ??? I don't have anything bad to say about either of the manufactures
#71: Re: NGK vs Bosch spark plugs Author: crocdino, Location: LeedsPosted: Fri Jul 13, 2012 2:39 pm ---- Go buy them from your local dealer. You'll get a nice box with Peugeot lions all over it.. With Bosch plugs inside!

#74: Re: NGK vs Bosch spark plugs Author: Johnbyron, Location: ScunthorpePosted: Sat Jul 14, 2012 10:39 am ---- Well I got standard ngk's in so how about we close the thread and I'll make a new one when my coil pack goes caput
#75: Re: NGK vs Bosch spark plugs Author: spike_202, Location: West midsPosted: Sat Jul 14, 2012 1:35 pm ---- Lol I think it was one Of them things like the ebc myth.
I did change mine when I 1st had my pug with ngk and did swap for both and it stopped the jurking.

#79: Re: NGK vs Bosch spark plugs Author: crocdino, Location: LeedsPosted: Mon Jul 16, 2012 4:28 am ---- I can't remember now! Maybe £20/25 for a set.
#80: Re: NGK vs Bosch spark plugs Author: bezford, Location: darlingtonPosted: Mon Aug 13, 2012 9:47 am ---- arent ngk considered a budget option-bosch are more expensive for a reason.....there better

#82: Re: NGK vs Bosch spark plugs Author: 206boyracer, Location: Sunny CornwallPosted: Mon Aug 13, 2012 10:22 am ---- Recently changed mine and the old ones were ngk. Never really noticed any problems with them. Put Bosch ones in and the only difference really was slightly better throttle response. But the ngks were really old.
Not disputing that ngk cause problems for most but from my experience they were ok.
I will only be using bosch from now on tho just as a precaution.
#83: Re: NGK vs Bosch spark plugs Author: bezford, Location: darlingtonPosted: Wed Dec 19, 2012 8:47 pm ---- Its mad how people seem to have a loyalty to a certain brand and are willing to defend them to the hilt in the face of total facts...its almost like football...
Its maybe what you grow up with...if your father used ngk or bosch or eyauk or whatever you will fly in the face of good sense and support regardless and relentless...
We love u bosch we do.we love u bosch we do.,
Or ngk i guess...

^^ this..... Is so true. People speculate then talk about it then other people just believe it as they have no reason not too!! It doesn't mean either of them will cause problems at all it just means you using what you trust

#88: Re: NGK vs Bosch spark plugs Author: Zitron, Location: West SussexPosted: Thu Dec 20, 2012 8:26 am ---- Just bought a 2.0 138 a few weeks ago and been giving it a decent service so I know where it's at. Had a whole lot of fun reading through the spark plug threads trying to decide which to get. Just decided to get the Bosch Super FR 8 ME plugs in the end, seemed like the safest option. I think there's NGK LFR5B plugs in there atm as that's what the receipts say (10k ago) and seems to run alright *shrug*
