Accel 3-263 Platinum Spark Plug Set

Accel spark plugs are platinum type and feature a platinum tip electrode and a pure copper center electrode.

The Accel 3-263 Platinum Spark Plug Set is designed with a platinum tip for greater durability than standard plug materials. The platinum tip helps the spark plug maintain its proper gap for longer periods of use, supporting consistent ignition performance.

Its reduced-voltage gap requirement can help minimize misfires, while the pure copper center electrode helps reduce fouling. These design features may contribute to improved fuel economy, smoother idling, and quicker acceleration.

This Accel spark plug set fits 1979–1985 Harley-Davidson XL applications, including model years 1979, 1980, 1981, 1982, 1983, 1984, and 1985. The set has a UOM of SET and is manufactured in the USA.
