if u keep the stock paper one changed out reg. it is the same hp as a k&n. if u like to clean the k&n often than your the same as a stock paper (not to dirty) dyno wise. never saw any dyno figs on the triple cai unit so can not say abt it. but imo you are prob. only going to see a few ponies at best on the dyno between em all and no diff. at the qm times or by seat of the pants feel!!! JIMO and i could be wrong like dennis miller likes to say! LOL
