NGK said the DCPR7EIX was the one to use in my 2005 TwinCam Harley. I was using the DCPR8EIX before. The bike is now harder to start. Might have to change back. Will be reading the plugs after a week of riding to work.

My compression is not stock and is at 10 to 1.
Cam is a HQ-0034G

      • Q:

        what about Harley's anti knock with their spark plugs? Does your plugs allow this feature to work?
        Asked on 11/4/2013 by zeke from Florida

        1 answer

        • CUSTOMER CARE

          A:

          Hi Zeke, my answer to your question on the NGK Iridium IX Spark Plug (DCPR7EIX) -part# 6046 is that 2005 and later Harley-Davidson EFI systems incorporate an "Anti-knock" feature that operates by reading the current resistance through the spark plugs. The use of any other spark plug other than 'Stock' plugs disables the anti-knock feature. I would recommend using the stock plugs for best results and to ensure the ion knock retard works properly.
