This modification delivers the maximum level of performance (+ 6mph) through easily installed air intake and pump enhancements. No internal engine modifications are required.
all the parts in the stage 1 kit are pretty easy to remove for warranty work. course depending on the dealer that won't be an issue. i know perry performance, riva, and barney's down here in FL are all cool about modifications. my local dealer on the other hand is not. riva is working on more parts for the 255's according to the guy i talked with last week about my 215.
