I have a stock 2000 convertible. I have just installed a Corsa "Pace Car" edition exhaust including the "X" pipe. I am thinking of adding a K&N air induction system. Will I need to also add a new MAF sensor and have the computor re-programmed? If a new MAF sensor is required, is there a preferred one? If re-programming is required, where can it be done? Is there any thing else I am not accounting for if I add this K&N system? Thanks for any help.
