Good To Know

Q: How do I know if my sparkplug cap needs replacing? A: Cracks, a loose fit on the spark plug, corrosion inside the boot, or rough running and misfires are common signs. A fresh resistor cap restores a clean, consistent spark connection.

Q: Does the resistor cap affect engine performance? A: The resistor element suppresses electrical interference without changing the spark the engine needs. It keeps ignition stable while protecting radios and electronic accessories from noise.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
