VN900 spark plugs

Pooker · 07-06-2006

This is my first V-Twin cruiser, I have always had sport bikes. The sport bikes seem to run better using "Iridium" spark plugs.
What is the best spark plug you can put in the Vulcan 900?
The manual calls for "NGK" CPR7EA-9. I have looked on NGK's web site and cannot find this plug????

I can't find a CPR7EA-9, either ...but there is a DPR7EA-9 that seems to be the one specified for virtually every other metric cruiser, so maybe a typo? I suppose it would be easy enough to verify by pulling one of the plugs and looking at it ...

Sorry, I don't know anything about Iridium plugs.

Kawasaki list two plugs for the 900; CPR7EA-9 and a CPR8EA-9, you have to order direct from Kawasaki.

Ask for NGK3091 is is the same as CPR7EA-9. The box has both numbers.

The correct number is 3901 (I have the plug in front of me and the package also has CPR7EA-9 on it.) Got them from NAPA
