I know induction kits can be bad on Scoobys, But im having my 2004 WRX mapped again next month and im trying to get a load of parts before I get it remapped, Last time it made 310bhp and 290lb/ft, I have a set of equal length headers going on, and im porting and polishing the Y-pipe thats under the TMIC, and adding a few more things that I havent decided yet.

Now im thinking of adding a APS cold air induction kit, I know that induction kits can be bad on impreza's, But surley if I get it mapped it should suck in more cold air then the standard air box, I wouldnt add a induction kit unless it was mapped.

What should I do, keep the original air box with Green panal filter or go for the APS induction kit.

the kits are generally fine as long as they are mapped in ok as far as understand....mines coming backto me with one fitted.

After doing a bit of research, I think I might leave the standard air box, I dont really want to start messing with the induction side of things incase I get it wrong, as the standard box and green panal filter seems to be running fine at the moment.

APS are an excellent bit of kit! It is highly advised that the car is mapped immediately afterwards as Andy F and Harvey are both aware of "possible" MAF issues with these units. Mine is fine and sounds awesome currently helping me to pull 367HP and 349Ft Lbs of torque on my MY03 WRX.
