I ordered NGK spark plugs for my 2002 Honda CBR 600F4i motorcycle.
The manual states I should use NGK IMR9A-9H.
However my dealer gave me IMR9C-9H.
He said that the C superceeded the A.
Is he correct, and is is safe to fit the IMR9C-9H instead of the IMR9A-9H?

 

it will work fine. the 9C one is what's in the 600RRs...

 

yo mang...you might want to double check the gap also.

 

buy ur sparkplugs at sparkplugs.com

 

Like Tahoe said u'll be fine. I have an 02 600f4i as well. I just put in 4 brand new IMR9C-9H. I had 7,500 mi on the 9C-9H that were in there. There was nothing wrong with them, but I had the bike stripped down, so I decided to do them while I had easy access.
