What is the best spark plugs to use with pacesetter lt's I currently have NGK TR55's but I'm having a problem with the tips loosening up, any other suggestions appreciated. Or what are ya'll using????
thanks,1sicss

 

I use NGK'S iridium. I have PS and full exhaust. they work great, I also am using MSD 8.5 super conductor wires.

 

Just put a small dab of locktight on the tip. I had that problem a few years ago with a set, but the ones I have bought lately look to be redesigned and don't loosen up.

 

I just got ngk tr55's. I'd probably go out on a limb to say 50% of people run ngk tr55 or tr6 for nitrous/boost

 

i used ngk tr55 with pacesetter lts on also and the plugs got loose but i retighten twice afterwards and never had a problem again
