Panel filters, Induction and cold air intakes

Does anyone have any suggestions - I have a K&N panel filter in at present but I think this may be restricting performance on 2001 WRX with Ecutec and exhaust finally done - surely basic induction kits (Powertec etc) are good but suffer from underbody heat and the "cold air" systems (APS kit) must get moisture in from the inner arch. Anyone got some suggestions - which route is best to follow???

having messed around with this on a dont laugh, vtr saxo, i found the best resuts on a friends rollers was from an enclosed filter which in my case was a bmc cda, panel filter in std air box was next best and a bare cone was the worse, on my wrx i have made an air box out of ally to enclose the filter

Get a Green Cotton Panel filter.... Proved to be the best as seen in ScoobyMagazine

You really only need induction kits when running BIG BHP.

Same as you, but with a classic. Was toying with the idea of putting a cold air tube from the bottom of the U bend (with resonator removed), into the bumper sitting below the indicator. Im sure im not the first, would be pretty effective though, and the principles of a conical in a box will be the same? :?

A good Cold air feed is always worth adding if you can. A known problem with induction kits on Scoobs is that the cone sucks in warm air in its normal position - which generally means a loss of performance.

However a cold airbox with a good cold air feed is very worthwhile and can give a healthy performance increse The inner wing is a good place to fit an air feed and just above the indicator is as good a place as any for forced induction
