How much horsepower do you think this alone adds

[@ZeroEmpire]

Thats hard to say. I've seen some dyno tests where it adds 5-10, but 5 or less is probably the norm. It also depends on what else has been done to the engine. On a stock engine I doubt that it'll gain very much. If you've done heads, cam etc...and are looking for that last bit of power it could be more. As seen from the restrictions in mine I do believe it's worth doing though. Every little bit helps and in the end it all adds up. Thanks for watching!
