#47: Re: NGK vs Bosch spark plugs Author: Johnbyron, Location: ScunthorpePosted: Tue Jul 10, 2012 3:13 am ---- I already bought some standard NGK ones over a week ago but then my mate told me about this rumour so I had to ask I couldn't resist it, I've done around 700 miles and not had a fault with them yet , I rang peugeot in scunthorpe and Peugeot in goole at dinner 20 mins ago and they both confirmed that Peugeot 206 come with Bosch plugs but they both said they have never had any problems with NGK and they both confirmed they haven't had any sort of statement saying they should only fit Bosch
#48: Re: NGK vs Bosch spark plugs Author: Big_Rich180, Posted: Tue Jul 10, 2012 4:43 am ---- This is really old news now, its your car your risk at the end of the day.
Everyone on here uses Bosch for a reason.

The fact they come with Bosch plugs but have never had a problem with NGK's.
#52: Re: NGK vs Bosch spark plugs Author: Johnbyron, Location: ScunthorpePosted: Tue Jul 10, 2012 7:12 am ---- Well I don't think that because they come in the car when they leave the factory has anything to do with the fact they don't work with NGK anyway Peugeot told me they are just Bosch that are used as standard not super fours

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).
