DRAG SPECIALTIES Spark Plugs - '71-'85 XL E18-6658SDS

Running vintage XL Harleys demands spark plugs engineered for reliability under extreme conditions—and these Drag Specialties plugs deliver exactly that. The 95% pure alumina insulator resists heat shock while the multi-rib design prevents flashover, ensuring consistent ignition across '71-'85 models. Pair that with a copper core electrode and nickel-plated housing that won't corrode, and you get long-term durability without compromise.
