MG ZR: Cams & Maps

Do they really make that much a difference? Is the intake system a restriction, I know on the 143 vvc it is since they up'd the air box size
Also do shiney intake pipes do anything bar looking nice? Smoother air flow rather than the ribbed plastic one

I think the ITG ones are slightly less restrictive, but make the car run quieter too, as soon as I switched from the K&N to the ITG the car was quieter and a little more pokey,
might have been as that's one of the things the 143s like, is good induction, throttle body and exhaust system.
but the two engines performance wise there isn't any difference tbh, bar the 160 had a stronger head that was about it.
