Do i need a alternator cover? and do I need the metal cover that goes over the turbo? i have a 02 wrx

whats the difference?

ya....stock turbo

I just got my 02 wrx tuned and im pushing 250whp and about the same for torque. Im pushing about 15psi of boost. I have a full catback exhaust with header and a short ram AEM intake. They said its a stage 2. Is this a good tune? This is my first wrx.

which filter is better for a drop in filter in a 02 wrx? Perrin or K&N?

whats a drop in filter? sorry new to subaru

sorry....its a 02 wrx stock

for my 02 wrx with no mods besides full catback. which is better cold air intake or short ram intake? any power difference?

i have a 2002 wrx that is all stock. no upgrades....do i need a aftermarket intake or will a stock air box do just fine?
