NGK Racing Spark Plug R5670-5 - Box of 4 for Select Harley-Davidson 1948-1974
$61.60
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1948-1974 Harley-Davidson FL and FX Super Glide models.
NGK Racing spark plugs are engineered to withstand the extreme thermal and mechanical stresses of high-performance environments. These plugs feature specialized electrode configurations designed to ensure consistent ignitability and durability where standard plugs might fail. Each R5670-5 plug is built with a copper core to maximize heat dissipation, preventing pre-ignition and fouling during aggressive riding.
- Trivalent Metal Plating: Provides superior anti-corrosion and anti-seizing properties, making installation and removal easier in high-heat applications.
- Pure Alumina Silicate Ceramic Insulator: Offers exceptional dielectric strength and enhanced heat transfer.
- Corrugated Ribs: Specifically designed to prevent flashover and electrical leakage.
- Triple Seals: Eliminates combustion gas leakage for consistent cylinder pressure.
- Special Insulator Nose: Optimized geometry to improve throttle response and prevent carbon buildup.
This set includes a box of four (4) NGK Racing Spark Plugs (MPN: R5670-5).
