As I said, I personally wouldn't put one on a car until 500bhp+ was wanted. Now considering I sell them, I think you can safely say this is honest advice.....
Have seen results on the Dyno £3k inlet against the spaced RS500 plenum the spaced RS500 was better. Although ive just forked out for a new £3k exhaust manifold im sticking with my Spaced RS500 . Ive seen no reason to buy one of these inlets at Power levels now approaching 800bhp.
