These injectors will bolt on and will work with a piggyback computer to alter the maf signal. Most european and american car injectors will bolt on with little to no modification. They just have to be high impedance and the flow that you are looking for. By no means was I telling anyone they should put these injectors on their NA. If you read my previos post I said a 22.5 lb/hr injector would be ideal for the minor flow improvements you are going to get with the NA 3.2.
