i looked up on the ngk website for my spark plugs and it said 6966 (imr9a-h9)but my bikes owner manual says imr9c-h9 (6777) and these are in my bike now.but i bought the 6966 so can i still use these or stick with what was in the bike?

 

looks like you are good to go

compare spec's , keys are same thread , same reach, same heat and resistors

My 01 takes the ngk 6966 according to the manual, I think you got the right one's.

 

Thanks for the help guys.....
