The NGK XD05F (part no. 8072) spark plug cap ensures reliable ignition performance with built-in interference suppression. Featuring a straight design with a 5 kΩ resistor, it is compatible with 10–12 mm spark plugs with threaded terminals, making it ideal for motorcycles, scooters, ATVs, and small engines requiring a resistor-type cap.

Ideal for motorcycles, scooters, ATVs, mopeds, and small engines where a straight resistor-type spark plug cap is needed.
