Which Performance Panel Filter?
I have a UK 2002 WRX and want to upgrade the air filter this weekend. From what i've read on this forum an induction kit seems like a bad idea so i'm going to fit a replacement performance filter.
What do you guys recommend, K & N or Green performance filter?

Will i loose out on any performance gains by sticking with the standard filter?
I've had the centre cat removed already and a larger bore exhaust from where the cat was to the back including back box. I plan on de-catting the downpipe and having a remap done soon. Are there any performance filters that aren't oiled?

hi,
green for me, and yes it gives a little more induction noise. to be honest the induction noise is the only definate difference i noticed.
cheers and good luck.

The O/E Subaru air filter is actually pretty good in terms of both filtration ability and power output.
To say that a K+N filter will screw up your MAF Sensor because of the oil on it is total rubbish, unless of course you are silly enough to grossly over oil the gause when servicing it. The advantage of the K+N is that it can be re-used so you can clean it as often as you want.
The performance difference between O/E and aftermarket panel in terms of filtration ability can be quite signifigant but in terms of power output is VERY marginal. Avoid a wide mesh filter which can let large particles pass which will bombard your MAF Sensor and worse still enter your engine internals.
