Resistor Sparkplug Cap for Yamaha Exciter 440

This resistor sparkplug cap is a replacement ignition component that links the spark plug to the ignition lead on Yamaha Exciter 440 snowmobiles, delivering consistent spark while the built-in resistor suppresses electrical noise. It matches the LB05EZ style cap used on these machines.

Overview

This resistor sparkplug cap is built to replace the original cap on Yamaha Exciter 440 snowmobiles from 1976 through 1981.

Good To Know

Q: What does the LB05EZ marking mean? A: It identifies the cap style so you can match it to the original part on your machine. Confirm the marking on your old cap or check your model's parts listing before ordering.

Q: Can I replace just one cap at a time? A: Yes, though many riders replace caps as a set when they show age or wear. If both caps look cracked or corroded, changing them together saves a second service session.

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