Perrin has a foam air filter element (which I put in) and a lightweight crankshaft pulley for FA/FB20 motor but I have not heard anything back from them regarding performance or CEL issues in our Impreza so until then, no pulley for me. No one has come out with our model specific axleback or catback exhaust yet although a few guys here had custom ones fabricated with off the shelf brand mufflers. As far as custom air intakes are concerned the only viable mod for our MAF sensored cars is the 'Hybrid' which replaces the plastic tubing from the MAF sensor into the intake manifold. You can hack up an existing CAI kit for the tubing/hoses/couplers/hardware and make it work as a few guys have done it. That is pretty much it in a nutshell. I am waiting for a catback exhaust to come out so I can get some of the boxer engine rumble out. Not much you can do with bolt-ons for the NA engines. I would tighten the suspension up, and put some lighter rims on the car to make it more fun to drive in the turns...
