Has anyone modified their air filter on their 9N? I am thinking of getting a new one for the "ROAR" but would like to know how difficult or easy it is to do.

I'm getting a K&N Filter tomorrow for my FSi. Apparently up's the MPG.

Petri, with a 57i kit on its own, do you reckon there will be much volume???

Roy.. K&N drop in panel is good enough, don't try the i-kit.. it draw hot air from the engine

Best one to go for is the second generation K+N or a viper, (although a lot more money).

A drop in filter may work better, because as DJ says, you're more than likely to have hot air coming in

That pic is Kind of old. Now I have the filter all the way to the front, behind the left light

Guys, Im pretty new to filters, please tell me, what does a drop on filter look like, and how much are they. Any ideas where I can get one?

Here is the website for K+N http://www.knfilters.co.uk and there is a search tool to find places that sell them.

I think you can order them through Halfords too.

The drop in Filter will be the same size as your stock filter now, but will look something like this :

Thanks Scorpio, ur a star. Will there be much of a noise coming from this type of filter?

From a panel filter you will hardly notice any difference in sound, but the engine will seem a little sharper and a bit smoother.

With the induction kit you will get the noise, but like I said before also the warm air. Kinda catch 22

If i get a drop in filter will this effect my warranty at all and i know slightly off the subject but if i got a new back box in what way will this effect my warranty?

I fitted a K&N to my FSi about a week back now. Made the car more responsive and upped the fuel consumption (50mpg to 52-57mpg) but I didn't notice any raspier sound...well, perhaps a little more raspier but nothing to write home about.

Bear in mind my car is chipped, so whether it was the SKN chip or the K&N (or both) upping the fuel consumption I don't know.

Roy.. which engine your 9N is..

I can help you to get the K&N parts no...

Posted: **Thu Apr 22, 2004 4:36 pm**

DJ, its a 1.2 55bhp. Thanks

I've just fitted mine now. Havn't had time to try it out yet though.

Very easy to fit, at least on the FSI. about 10 mins, 5 mins of that looking for a screwdriver

I'll let you know how it goes!
