Spark Plugs

Designed for a sharper, leaner spark with tapered nickel/chrome alloy tip and copper center electrodeMade in the U.S.A.

Superior construction for serious powerVersatile plugs with wide operating heat ranges prevent fouling from running too cool and preignition from running too hotFeatures high alumina ceramics for improved heat dissipation and electrical insulation,...
