Resistor Sparkplug Cap for Polaris Indy Storm 750

This resistor sparkplug cap, reference LB05EZ, links the ignition wire to the spark plug on the Polaris Indy Storm 750, holding a solid connection while its internal resistor suppresses radio frequency interference.

Overview

The resistor sparkplug cap is a replacement ignition part for the Polaris Indy Storm 750 from the 1993 model year. It fits over the spark plug terminal and accepts the ignition lead, keeping spark delivery steady under the vibration of a triple-cylinder snowmobile engine.

Specs At A Glance

Good To Know

Q: What are the signs of a failing sparkplug cap? A: Rough running, misfires, hard starting, or visible arcing around the boot often point to a bad cap. A quick resistance check with a multimeter can confirm whether replacement is due.

Q: Can I replace just one cap at a time? A: Yes, caps can be replaced individually, though many riders replace all of them together on multi-cylinder engines for even ignition performance. Match the reference number to the originals.

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