We advise against the use of oil impregnated foam filters because of the number of cars we have seen where the oil has come off the filter, into the air intake and burned on the hot wire air flow sensor causing the car to run badly.

cas anyone found this to be true ????????

Ramair(sp?) filters were known to do this and the PPP for later model year cars excludes it for that reason. ITG apparently cause no problems due to lighter oiling.

I have had problems with both ITG and Ram Air problem was solved using K & N. The car ran better with one of these on

I just had an ITG put into my MY98 at TSL. It came out of Pauls 22B. Good enough for the 22B - good enough for me.

There was green gunk in the bottom of the 22Bs air box, but as Paul pointed out, any residue sits in the bottom of the air box the opposite side of the filter and thus MAF.

In his opinion there is no problem with the ITG filter. He is only changing to green cotton as they are now the sponsor not ITG.

ITG and Ram air are the same filters, they used to be the same co but parted a couple of years back but still produce the same filters.

Before I knew about the Maf risks (3 years ago) a Pipercross oiled foam filter meant that my Audi one needed replacing £190 + fitting.
I've stayed with the std filters ever since. Not worth it for 3 or 4 bhp.

i have got a JR filter in mine. it is a dry filter so wont cause any MAF problems, however it does get dirty quick and to clean you need to soak and the let it dry for a while...
