Good To Know

Q: Why use a resistor sparkplug cap instead of a standard one? A: The resistor element limits electrical interference that can affect nearby electronics and radio equipment. It is the correct style for machines that came with a resistor cap from the factory.

Q: How often should a sparkplug cap be replaced? A: Caps wear out from heat, vibration, and moisture, so replace one that is cracked, corroded, or loose. A fresh LB05EZ cap helps restore consistent spark delivery.

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