LB05EZ Resistor Sparkplug Cap for Polaris XCR 120 Pro-X 2000-2006

Resistor Sparkplug Cap for Polaris XCR 120 & Pro-X 120

This resistor sparkplug cap, reference LB05EZ, connects the ignition wire to the spark plug on Polaris XCR 120 and Pro-X 120 machines, suppressing radio frequency interference while delivering reliable spark energy.

Overview

The resistor sparkplug cap is a replacement ignition component built for Polaris XCR 120 and Pro-X 120 snowmobiles from the 2000 to 2006 model years. It seats onto the spark plug terminal and the ignition lead, holding the connection secure against vibration while its internal resistor cuts electrical noise. Riders and mechanics servicing these 120-class machines will find this resistor sparkplug cap a direct-fit answer for worn or cracked original caps.

Built For Performance

• Internal resistor suppresses RF interference with onboard electronics and radios
• LB05EZ reference number for straightforward cross-checking against the original cap
• Rubber boot grips the plug ceramic to resist vibration pull-off
• Terminal design matches standard spark plug tops on 120-class engines
• Compact body fits the tight clearance around small-displacement cylinder heads

Fits These Machines

• for Polaris XCR 120, 2000-2006
• for Polaris Pro-X 120, 2000-2006

On-The-Job Use

• Routine ignition tune-ups on 120-class snowmobiles
• Replacing a cracked or intermittent original sparkplug cap
• Track-side troubleshooting of no-start or misfire conditions
• Seasonal pre-ride maintenance checks

Good To Know

Q: How do I know if my sparkplug cap needs replacing? A: Cracks, corrosion on the terminal, or a loose fit on the plug are common signs, and a cap that arcs visibly or causes misfires should be swapped out. Inspect the boot and terminal each season.

Q: Does the resistor in this cap affect engine power? A: No, the resistor only suppresses electrical noise and does not reduce spark energy enough to change performance. It is fitted as standard on many machines for interference control.

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