On the Stillen site the description of this produyct claims to "add 11 horsepower at 6,100 RPM. " Does this apply to the crank or the wheel? Also I've searched the forum and haven't discovered an overall consensus on whather to go with the z tube/jwt pop charger combo, ztube/k and n, or just buy this hi-flow cold air intake from Stillen. Im only looking to spend about $250 (for the moment :twisted: ) for a minimal boost in performance whether it be HP or MPG and of course to make the FX louder! Can somebody point me in the right direction?
