My friend tried an iduction kit on his 1.2, made absolutly naff all difference except make it louder. Then he got rid of that kit and just changed the exhaust manifold for a 4-2-1 system, that did make an improvement.
Induction kits are pointless for the k10 because the inlet manifolds are crap, way too small and restrictive. If you can find a performance inlet manifold, even if it uses the origional carb, it'll make a hell of difference to the motor.
Drilling the airbox? :laugh: Yeah that's gonna help the performance when your carb is sucking in dirt and water, cheap ghetto mods :laugh:
