I read through the basic bolt-ons suggestions at the tops of the forum, but I couldn't find some of the items listed on the websites. I have an '07 ZX4 SES which has only ever had brakes and oil changes. Car's paid off and I'm looking to add some mods to get that extra kick instead of purchasing a new car. First thing I was looking at was replacing the intake with the K&N short ram and then grabbing the FSWERKS racing exhaust. Would these both be worth it as far as performance goes, and if so which order would be best to purchase them?
