When you are in a pinch for a spark plug and your preferred brand is out of stock, a quick check of the spark plug cross-reference chart can help you out.
The chart below is based on our preferred brand of plug, NGK. We have listed NGK plugs for motorcycle, ATV, moped, golf cart, snowmobile and personal watercraft plugs. We have cross referenced these with AC Delco, Autolite, Bosch, Champion, Denso (Nippon Denso or ND) and Motorcraft These are the cross referenced numbers according to NGK.
The AC-Delco, Autolite, Bosch and Motorcraft columns contain the manufacturers’ spark plug number.
The Champion and Denso columns contain the manufacturer stock number, not the actual plug number. For example the NGK spark plug A6 is NGK stock number of 1010. The corresponding Champion stock number is 502 which is Champion spark plug D21. Similarly the corresponding Denso stock number is 5002 and the plug number is M17.
Plugs are listed alphabetically by NGK plug number. It does not list every available plug from the other manufacturers.
