hey you guys. i drive a 03 wrx and i was wondering which brand intake system would be better for performance and gas mileage? aem? K&N? thanks!

 

the stock is good enough for up to 400HP.

this link is a good source of info about intakes. If you still feel like you want an intake even after reading this. I would choose from the list they have there of intakes that work well with the car.

Here's the link to the other threads unabombers made.

Very helpful and TONS of information.

It is better to run the stock intake (even though i run a spt short ram with heat shield lol)..most prefer the silencer delete mod with a k+n drop in. very easy to do just search or shoot me a PM if you can't find the thread on how to do it.


Remember that if you do get an aftermarket intake it would be a good idea to get tuned for it.


Good Luck
