Good To Know

Q: How do I know my cap needs replacing? A: Cracks, looseness on the plug, or rough running that clears when the cap is wiggled are common signs. A fresh resistor cap restores a stable ignition connection.

Q: Does the resistor affect performance? A: The resistor is there to suppress electrical noise and does not reduce usable spark energy. It keeps ignition clean for the machine's electrical system.

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