The best idling plugs I found are the Densos ad the TR6s....

 

promod,

Thanks, I hope the TR6s will be in for a while because I do not plan on installing any more plugs after this. Although, I will say that this time around should be much easier after doing it once.

Thanks again, Jim

 

Kinda off the beatin path here, but I use Autolite 103's in my Syclone, and it seems like I'm always changing plugs. Can't seem to clean them either. Once they're fouled, they're done for.

Which plugs are comparable to the 103's AND will hold up well with leaded race gas and lotsa boost.

Thanks!

 

when it comes to lightnings I've only ever heard of ppl using denso or TR's
