LB05EZ Resistor Sparkplug Cap for Yamaha SS 440 1980-1985

Resistor Sparkplug Cap for Yamaha SS 440

This resistor sparkplug cap is a replacement ignition component that connects the spark plug to the ignition lead on Yamaha SS 440 snowmobiles, cross-referencing LB05EZ.

Overview

This resistor sparkplug cap is a direct-fit replacement for the ignition lead connection on Yamaha SS 440 machines from 1980 through 1985. It seats over the spark plug terminal and suppresses ignition noise while delivering consistent spark energy. Riders and shops keeping older SS 440 snowmobiles running will find this resistor sparkplug cap a practical replacement for a cracked, corroded, or loose original cap, and it carries the LB05EZ reference for easy matching.

Built For Performance

• Resistor design suppresses ignition interference with onboard electronics
• LB05EZ reference for straightforward cross-matching
• Durable housing resists heat, vibration, and moisture exposure
• Solid internal contact for consistent spark transfer
• Push-on fit over standard spark plug terminals
• Compact body sized for tight engine compartment routing

Fits These Machines

• for Yamaha SS 440, 1980-1985

On-The-Job Use

• Routine ignition tune-ups on vintage SS 440 snowmobiles
• Replacing caps cracked or fouled by years of trail use
• Restoring consistent spark on machines with hard starting
• Preventive maintenance before the riding season begins

Good To Know

Q: How do I know if my sparkplug cap needs replacing? A: Cracks, corrosion at the terminal, or a loose fit on the plug are common signs, and hard starting or misfires can also point to a worn cap. Since this is a resistor cap, a failed internal resistor can interrupt spark entirely.

Q: Will this cap work on my 1980-1985 SS 440? A: It is listed for Yamaha SS 440 machines from 1980 through 1985 with the LB05EZ reference. Confirm your model year and serial number before ordering to be sure of the match.

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