Ive got a K+N 57i Induction kit on at the mo.
After the SW RR day (sod the bhp figure), its the graph that worries me.
It deffo needs a full service which it will have in the new year. But I was thinking, could the 57i kit be causing more hassle than good. Should I just put the old airbox back in (drill some large holes on side and get a panel filter)?
Engine is c20ne, 2.0 8v.
