Good To Know

Q: How often should a sparkplug cap be replaced? A: Inspect the cap whenever you service the ignition system, and replace it if you find cracks, corrosion, or a loose fit on the plug terminal. Worn caps can cause misfires that are easy to mistake for other ignition problems.

Q: Does the resistor in this cap affect engine performance? A: The resistor is there to reduce electrical interference and does not measurably reduce spark energy on a stock ignition system. Use it as a direct replacement for the original cap style.

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