Harley Spark Plug Cross Reference
Harley Spark Plug Cross-Reference
Below is a cross-reference list of spark plugs for use in most Harley models. While the motor company only recommends use of their original equipment Harley brand spark plugs, the other brands often exceed original specification and will not void your warranty. NGK and Autolite among others have always been a preferred performance plug for Harley motorcycles. In addition it is often more convenient to use aftermarket spark plugs aside from the enhanced performance. All sparkplugs listed meet or exceed manufacturer specifications.
