Replaces Harley Davidson 5R6

Manufactured by Powermadd/Cobra

  • Unique electrode shape maximizes the power created by the spark plug - Diamond Fire technology
  • Electrode is a combination of performance and technology that results in an improved flame kernel shape
  • This flame front ignites the bulk air/fuel mixture faster, moves heat into the combustion chamber faster and creates a more localized pressure front for faster pressure rise during the cylinder power stroke
  • The result is more complete combustion and an improvement in engine performance

WARNING: Cancer and Reproductive Harm -

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 spark plugs listed meet or exceed manufacturer specifications.

NOTE: Iridium plugs should only be used with electronic ignitions, not for use with point ignitions.
