MG ZR: Cams & Maps

[Niall]

Thing you need to remember is, cone filters will add noise but thats about it. Just think about the GTI6 air box. The amount of design that went into that would of cost a significant amount. Why do people think getting rid of that and putting in something silly basic and not designed for that car will be better?
Panel filters or filters that go into the original air box are nearly always the way to go!
