I have been interested in using the E3 spark plugs in my 2001 XL1200C. I have used these in some small engines and really like them. Has anyone used these in their bike or know the E3 item# ?

 

there is no magic sparkplug that can make an engine run that much better. beisdes, those E3 were designed for small motors and two strokes.

a few months ago i was interested in them as well. was disapointed by the results

 

thanks for the feedback, has anyone else tried these plugs?

 

I use NGK iridium (DCPR7EIX) in my 06 1200C.I noticed an improvement in throtle responce and milage.

 

I am a NGK fan

 

Best plugs made

 

Yep, lovin' the NGK's
