blow off valve

[Burn N' Up]

Get the car back to mint stock, then start getting crazy. When you do, get the K&N FPIK system or go to supra sport and get the LIPP 3" intake adapter. Then throw out whatever filter they give you, and go buy an AEM Dryflow airfilter. Superior in everyway to a K&N and it won't damamge your MAF sensor which costs about 300 bucks.

Edit: for blow off valves the greddy's are good, the type S sounds fun. The HKS SSQV is what I have because you can use it under ay boost pressure and it adjusts its self. The Greddy needs to be fine tuned like almost every other non SSQV
