I have also went back to the cr9eh-9's as the Iridium plugs do not seem to take the shock of being off road (in the sand) and seem to fowl out easier then the standards. I race mine down the track and have not seen any time differances using the two plugs.

 

*he's aliveeeeeeeeeeeeee*

Which ones did you get???? The iridiums will last longer between needing to be changed. For the few extra dollars ($3 a plug) it is worth it. But what did YOU decide????
