I've been looking around for some Iridium spark plugs and I have hit a road block.  I am getting conflicting part numbers.  I have a 1978 CB750K.  The Googles tell me the part number is DR8EIX.  However, parts suppliers are giving me a conflicting number and saying that the DR8EIX is for a Kawasaki.  As far as I know it may work in a Honda, a Harley, a Kawi etc.  

If anyone has any experience with these could you tell me which part number I need.  As far as I know the engine is original.

Thanks Guys!
