Hi, i hve one of these for my ek4 for ages... yet to fit it cos iam concerned it will make my car slower!!! As i hve no engine internal mods, i guess this is the case..?
I only hve a full exh (header 4-1, de-cat, b-pipe & back box) air intake fitted.
Would replacing the stock B16A fuel rail help when fitting 70mm throttle body???
