I've got the CBR COP setup for my car however I'm just now realizing that the ends of the coils are smaller...and I need the threaded end for a spark plug. What did you do to get around this?

 

what the hell are you up to eric?

anyways use the ik27 denso's. have fun paying for them though. clubplug.net has the best price and free shipping if you buy enough.

 

k22pr-u are cheap "ngk bkr7e" equivelants, good for 500+, and then the ik27's are good for an equivelant heat range 9. the iridiums were the only plug i could find above the k22's unfortunately they are like 12 dollars a pop.

 

Im from BFE where regular Iridium's cost me 10 bucks a plug! lol. thanks guys!

 

Denso iridiums are all i've found that are worth a damn. IK27's are 9's and IK 31's are 10's.

 

thanks tony!
