OK i just found out about this i don't know what its about and how you go about this but an old guy at a truck stop seen i had a nitrous tank in the back of my car and we started to talk and he said back in his day side gapping plug was the way to go with N.O.S and supercharge to get that extra boost so what is it.

 

It's when the ground electrode is cut back so it doesn't shroud the center electrode. It's worth about 1 or 2 HP over a conventionally gapped plug, but most "performance" plugs already come gapped that way.

 

ooo ok thank now the important question is it worth a try or should i just keep with my $1.25 copper plugs

 

You could just do it to your $1.25 copper plugs.

 

yea whats to lose and some cheap hp sounds good to who knows may be my nitrous will hit harder lol thanks

 

I doubt you'd even notice. Certainly it's not worth the trouble of pulling the plugs to do it until it's time to change the plugs anyway. Don't get too carried away trimming and shaping the end of the ground electrode with nitrous or you'll end up making a glow plug.

 

well its not to much of a different theres a different exhaust sound like a popping and at high revs it a deeper sound lol haven't hit the nos yet need to get the bottle filled just to cold to be using nos lol
