you'll want to runner a colder plug like NGK BKR7E

IIRC T-28's use plugs which are one step colder but you may want to call PES and ask them direct.

they usually stock them, I bought mine for $1.68/ea. you can order them <a href="http://www.advanceautoparts.com/">here</a> if not.

Use NGK PFR7B. It's the plug that comes with the APR Stage3 and should come with the PES kit.

aren't the best choice plug in a forced induction environment. the copper plugs are able to get rid of the heat a lot faster, and efficiently, the only downside to copper is the more frequent replacement schedule. but at less than $2 a pop, I'm down with that.

car with an APR or PES kit. The only plug I've been able to keep for a good 20K miles is the NGK PFR7B. Denso Iridium IK-22s are also OK, but they require more attention to gapping and tend to go bad more quickly.

Everyone running and APR Stage 3 kit uses the NGKs, and many if not most people running PES kits.

of stumbling problems, misfires, etc. The legend about platinums seems to only apply to those multi-electrode platinums that you can't set the gap on. The NGK plugs are traditional single electrode plugs and as long as you gap them properly to around .030-.032 they work like a charm.
