Is everyone just running the NGKs or is there something that actually works better? I think the NGKs are great but looking for other options if there is something better. Just put on my RKT head and pistons so I want to start fresh. BR9ECS is what is in the sled now.

I've always run NGK's in all my sleds and so far in 18 or so years I've only had one foul on me

I ran the IRIDIUM BR9ECSIX, in my sled all last season. Sled ran great, no fouled plugs. Claim they add 3hp. And they do... In your head anyway. Ha

I put in the same plug and dont notice any difference. The ony thing I did see is that i may have a bit of detination on the tip of the plug. I need to run better gas.

I didn't notice a difference either, but I like to pretend I'm getting my money's worth. No destination for me though.

Yah also ran the iridium plugs - ran good - no fouled plugs - guess kinda hard to notice suggested hp gain - only thing I noticed was the price difference

If you have the RK head you need to run BR9EYA.
