Thanks for the input guys. I bought the car from a dealership so I think they've done the filter, put new spark plugs and whatnot, but i'll give it a check. did some more research and I was thinking of starting by replacing the axleback exhaust. Does anyone know how much that should cost me if i get it done at a garage? And how much that might improve performance ?

Hi guys, I just bought my first subaru A 2007 Impreza 15S newly imported I don't know the first thing about car mods and was wondering if anyone had any suggestions for the cheapest things I can do to improve performance? I've done some research and it seems like getting a cool air intake will help and is pretty cheap? Any suggestions/information would be appreciated!
