I have an 08 DI with 76k miles on it. I wanted to know if the mods I want to do are worth it for my car and if it would impact my car in a negative way. I wanted a CAI, ported throttle body, vmax iceolator, a catch can (obviously not for performance), and a tune once I get the bolt on mods. Obviously I'm not gonna get crazy gains...don't want that. I am interested in better response, fuel efficiency, etc.
any help would be appreciated
