Define performance plug set. Do you feel anything when it pops?

the jacobs high energy core 8.5mm plug set from intense. and the only thing i feel it a little bit in the gas pedal, but no real hesitation in acceleration.

i scanned the car and there are no misfires happening at all, even then the popping occurs.

Ah, plug wires.

Motor mounts?

not sure if that would be a possibility, kind of hard to explain the sound.... how hard/expensive is it to replace the motor mounts?

pcm and wires did';t help... i am pretty much lost.

Did you regap the plugs to .05 or .055?

i regapped the plugs to .55

Any ideas left as to what it may be? i normally hear it at wot when the car downshifts, or when first accelerating and then less prevelant after that. it still pops in second gear at 80 mph and wot. i have no clue what it may be, and maybe the popping is related to the KR i am am getting? i'm not sure on this but i'll just keep trying to figure it out.
