Not sure what the factory specs are....will have to check

So, the issue of spark blow-out at high rpm is a direct result of plug gap, more so than heat range of plug?

Going with a "colder" plug will help with detonation issues caused by increased cylinder pressures of high boost?

ive sprayed as much as 125 threw my car on top of the 17psi on the eaton with no issues with the plugs, no breakup etc. James has done extensive testing with the TR6's he recomends running them at .032 or so

some people will report some low rpm misses with the tr6's, this is pretty normal with cobra's, but its not bad at all.

Thats what I was concerned about.....reports of missing, sputtering, misfires, etc. in the lower rpm range....causing driveability issues. Had now idea as to the severity of these symptoms. Thanks for giving your first hand experience!

My next mods are lower pulley, and maybe stage 3 port on the HEaton.....will the TR6's be the right plug then....??

Thanks again for your reply and info. It does help alot, and is most appreciated!
