I picked up an 8th Gen Civic Si 2009, it already has an Injen CAI and an Apexi Exhaust System. Should I purchase the Flashpro or should I add a Throttle Body Spacer and Thermal Gasket and Stut Bar? I don't plan on racing or anything anytime soon but I do want to have fun with the car. Thank you. V/R...
