I have a 2002 camaro, i recently put a set of ngk plugs in it and ever since that it has a missfire,i was wondering since i have atick polluter cam and ls6 heads do i gap the plugs diff from the stock gaping. and also what would be a good plug to run in it?

You probably cracked one while installing them. Take them out one at a time, inspect and re-gap each, replace broken ones. NGK TR6 is fine @ 0.035.

^^ yep or maybe you didnt seat the wire good enough. .041-.035 is good on the TR6's IIRC they come gapped at .041

which plugs did you put in... the tr55's part number in most stors is 3951 and that is pregapped.

My guess would be a wire off (or as said above cracked during installation). If you don't hear a distinct click try again. I had a lot of problems with MSD wires and switched to GM LS7 wires because I couldn't get them on very good after my hand injury last year. I had a lot of misfire issues as a result. The GM's seem to go on better and definitely "click".

I have found quite a few bad plugs lately they have had no cracks or visual defects but have had weak to no spark at all.
