If you are happy to accept increased induction noise (and maybe a slightly better end result) go for an induction kit. I have an ITG panel filter (£40 + Vat from Scoobysport) which is like the Ramair filter but has a metal gauze for rigidity and is also cheaper. 290 bhp and 258 lb ft speaks for itself although I don't have any 'before' figures. The car felt quicker, particularly at the top end and there is increased ability to run on with a trailing throttle. Fuel consumption is better too, 1 mpg perhaps.

We are seeing number of problems on cars with oil impregnated foam filters.
The oul comes out of the filter as a mist and burns on the hot wire causing incorrect output from the sensor.
I have just come back from Japan and they were shocked that we did not know this. They have not used them seriously for sometime.
Use a paper or K&N style filter for element type or the dry BLITZ stainless steel mess induction kit.

57i kit not yet available for my99 . I was down at warrington last week getting my car measured up for it.they told me that subaru had enlarged the air intake (this is where the extra 4 bhp came from). 4 to 8 weeks for production and mine will be free yippee.also going to send me a panel filter while waiting. cannot wait to see my car on the instructions my only claim for worldwide fame and i am not on the photo boo hoo.

I'm planning on changing the air filter on my '94 WRX sports wagon, and from what I read it seems that the ITG is the best buy...is there a specific part number for this model ?? Thanx..

I am thinking about 57i or Pipercross induction kits for my MY98. Does the oil problem affect these kits? I already have a K+N panel filter and Janspeed rear box and the car produces 246BHP and 230 torque on Power Engineering Dyno - can I expect any increase on this with the induction kit and a dump valve?
