CCH587 Copper Plus spark plug. H8C

The Champion Copper Plus H8C spark plug is a staple for classic Sportster maintenance. These 14mm threaded plugs feature a 1/2 inch short reach and are the correct fitment for 1954 to 1956 KH models as well as 1957 to 1985 XL Sportsters. Engineered with a copper-core center electrode, they offer superior heat dissipation and reliable ignition. To ensure they stand up to the elements, Champion uses a patented Ultraseal coated shell that prevents corrosion and maintains a clean appearance over time. These plugs are a direct replacement for OEM 32338-04 and are used with a 21mm socket. This product is sold as a set of four, perfect for keeping your Ironhead or early Evo Sporty firing perfectly.
