Universal Parts 50cc 2-Stroke Spark Plug Cap

Universal 50cc 2-Stroke Spark Plug Cap

Restore consistent spark and engine performance with the Universal Parts Spark Plug Cap. Engineered for 50cc 2-stroke scooters, this high-insulation cap ensures a secure, vibration-resistant connection between your ignition wire and spark plug. Designed to prevent electrical arcing and misfires, it is an essential replacement for cracked, brittle, or corroded caps that struggle to deliver power in damp or high-vibration environments.

Technical Performance Features

• Weather-Sealed Design: Features a robust outer shell designed to deflect moisture and road spray, protecting your ignition path from short-circuits during wet-weather riding.
• Vibration Resistance: Internal tension clips provide a "snap-lock" fit onto the spark plug terminal, ensuring the connection stays seated over rough terrain.
• Universal 2-Stroke Fitment: Specifically sized for the 10mm spark plug terminals common on small-displacement air-cooled 2-stroke engines.
• High-Dielectric Insulation: Manufactured from premium materials to contain high-voltage current, preventing "leakage" to the engine frame or cylinder head.

Comprehensive Fitment Guide

This cap is a standard replacement for 50cc 2-Stroke scooters, including:

Technical Specifications

• Overall Length: 71mm
• Wire Inner Diameter: 7mm (Standard Ignition Lead)
• Plug Inner Diameter: 10mm (Standard Terminal)
• Angle: 90-Degree (Offset)

Mechanic's Note: A loose spark plug cap is the #1 cause of "intermittent stalling" on 2-stroke scooters.

Installation Hack: Trim 1/4 inch off the end of your ignition wire before screwing on the new cap to ensure the internal "spike" hits fresh copper for the best possible connection!
