I've recently changed my induction kit from a pipercross that was on't car when I bought it to a k&n one on the advice of Andrew Carr because the foam filter is not as good as the k&n one, now under low acceleration the car has developed a slight judder, it goes when u put ur foot down. Could this be due to the change in filters?
Is the induction pipe the same internal diameter as the MAF could need rescaling, it's possible the K&N breathes better so could be sucking in more air which the ecu has to recalculate, just a possible that's all?
Yeah its the same diameter, that's what I was thinkin, might have to put the pipercross back on, can't afford another remap.
induction if andrew as already mapped the car it would only need a tweek off him at cost obviously but cheaper than a re map :wink:
I was going to advice to put standard air box back on. Make sure the air filter is mounted securely :wink:
