Panel filter or Induction

guys,

Anyone got any advice on whether to just buy a panel filter or go for the full induction kit, and which ones ???

my warranty on my STi is coming up and Im getting itchy fingers.

Scoobymag did a good piece on Filters... The best option is a Green Panel filter....

Induction kits can cause MAF failure and do not give much if any improvement over the Green panel filter....


The Induction kits do give you the noise if that is something you were looking for and not all induction kits are bad... APEXi do a good one

i would stick with the Panel filters.
More hot air is drawn in with induction kits i think, resulting in less dense air and reduced performance.

Panel filters I'm told arent any good over 350bhp.. so if I'm thinking of 350bhp+ I'm going to stick with my induction kit..

Could always stick a little fan in there so the air is cooler

You can get induction kits that locate the cone in the inner wing and you retain the air ram at the front. This gives you the induction sound and keeps the feed with cool air from outside the car. I believe the APEXi is one of these types. If you are not going BIG bhp I would stick with a Green Panel filter......
