i just upgraded my plugs from the stock to ngk iridiums. the gap is .44 and i got them straight from the NGK site. however after installing them, while the car is idleing and in neutral i hear the car as though u turn it off and hear the clicking sounds. is this normal or did the plugs change something? are these plugs correct for an NA?

I have the NKGs, and have not noticed anything different about the car. (I'm NA also) but then again I added the HKS coil unit at the same time.

Nakor.
