I recently bought an ITG panel filter for my MY99 UK impreza.
Reading through the forum I have now realised could possibly have made a a mistake as it damages the MAFsensor.

Is this true?

I have still kept my original aifilter, should I put this back on.

Are there any alternatives to the ITG filter that would improve performance but not damage the MAF sensor?

 

Wouldn't use it if I were you.

Get a K&N or Green cotton one.

ditto that, a mate had the ITG, when we took it out is was completely caked in thick black gunk. christ knows how the car got any air at all.

K&N or green (my choice)

Neil.

 

Green cotton is the choice of the moment......

Though i ran an ITG for 3 years without a failure on the MAF.....

 

K&N all the way - don't think I've ever used anything else on my cars.

little'un

 

from what i've heard, k&n and green are made by the same people to the same spec etc, so either of these will be fine.

i ran an ITG for about 2 years, read a thread about it killing the MAF so changed it for the green filter, a week later the maf died. what killed it, the ITG or the green? all is fine now though

 

k+n.
but when you come to clean it dont use too much re-oil on it[just follow the instructions from k+n]

 

Get a Green Cotton Panel filter TSL Motorsport do them.

 

what about the sti, seems ok to me just wondering why it wasnt mentioned??

 

Because the Green Cotton came top in a recent magazine article....
