I been looking at upgrading my air filter as i have a cheap £30 one on, and I was about to buy the 57i but on the site it says:
2001 PEUGEOT 206 1.4L L4 F/I - All
Street Legal In All US States: No
TUV Approved (Europe): No
Is it street legal??

Yes.
It's an emissions thing.

From reading the webpage, it is as CD says, it's about emissions.
From the sounds of it, it increases your emissions. As a result, you could fail the MOT (unless you change it just before hand) or get the EML coming on from a reading from the O2 sensor.
The extra emissions may also cause the catalyst to prematurely fail.
The best thing to do is ask K & N why it is not TUV approved and what that could mean for your engine.

Does this mean the one I have on could be doing the same?
I have removed the airbox and fitted a (cheap) cone air filter in its place, jsut using the standard rubber pipe? It has a cold feed fitted as well.

I think its all for the American market.
Some states in America have very strict emissions rules, this is why some cars are supplied with pre cats.
The only thing I would say is get the 57i Gen 2, its better and has more heat sheilding, I had one on the MR2...made a right noise lol.
Dont worry about the emissions stuff, your car wont fail an MOT because of the air filter.

Get a panel filter, less hassle
They didn't put thousands into designing the standard air housing setup for nothing

I thought TUV was a quality standard, maybe have a look at what the TUV standard covers.

"57i Intakes are not legal for use in California and other US States adopting California emission standards."
Thats taken from the add.
If they say its ilegal for that they would say its ilegal for UK.
It is legal, stop worrying about it.
If your that bothered why not ring K&N and find out for sure.

In a number of US states it is illegal to add any modification to a car that raises it's 'smog' levels, as set by the state of Commiefornia, I mean California  . I read a whole chapter in an MX5 tuning book about it

Hello
Thank you for your enquiry. TUV approval does not apply in the UK. Fitting a K&N will not lead to MOT failure or that of the catalytic converter. Does someone have proof regarding MOT`s /cats. and K&N? Some comments posted on forums are from people who should not even be pulling the bonnet catch. By the way, emissions are improved when fitting a K&N. This is due to the increase in air flow to the engine which is beneficial when it comes to MOT time. Please feel to post on forum.
Regards
EDIT: BTW this was a email reply lol

Using a K&N filter in theory adds just a tiny bit more air into the engine. On cruise etc the lambda sensor monitors the mixtures and adds fuel to create the correct air fuel ratio entering the engine. That way the cat will work just as it did before.

Where is the bonnet catch?
What is it you hope to achieve by fitting a non OEM filter?
It may stop finer particles of dust getting into the engine compared to an OEM filter, but the dust particles in the UK aren't a major problem to vehicle engines.
Yes you can put more air into the engine which in turn will require more fuel (which is where the couple of extra HP comes from). The more fuel/air mixture you burn means that the gas being expelled increases, therefore increase in emissions. If the engine cannot burn all the fuel/air mixture before the exhaust stroke, raw fuel is passing through the catalyst, which in turn eventually rots the metal within the catalytic converter.
On older carburetor cars, you could adjust the fuel air mixture by turning a screw. If you wanted a lean burn engine, you would decrease the fuel going into the engine, if you wanted more power, you would increase the fuel to air ratio. On modern injection engines, the computer measures the air flow and adjusts the fuel delivered accordingly.
Edit, just seen that your comment was taken from a reply, I'm guessing from k & N filters. Email one of the goons from ebay that sell the magnets that wrap around the fuel pipe and ask if they decrease fuel consumption. They will say "yes", but they are salesmen, they want to make the sale so will tell you what ever you might believe in an effort to make you part with your hard earned cash.
Be interesting to put a car on an emissions test machine with and OEM filter and then swap it for a cone and see if there is a massive difference.

Ha lol
And well with the cheap crappy one i have on now, i can feel very slightly when i put my foot down, it is little more instant, so i figured if i went with a full induction kit(57i) would improve that, also sound is pretty nice so yeah lol.
