NGK Sparkplug Cap for Polaris 250 Scrambler 1985-1986

NGK Sparkplug Cap for Polaris 250 Scrambler

This NGK spark plug cap provides a secure, resistance-suppressed connection between the ignition wire and spark plug on the Polaris 250 Scrambler, replacing worn or cracked original caps so spark reaches the plug reliably.

Overview

This NGK sparkplug cap is a direct replacement ignition component for the Polaris 250 Scrambler built between 1985 and 1986. The sparkplug cap seals the top of the plug against moisture and vibration while suppressing radio frequency interference from the ignition system. It suits riders restoring or servicing a classic Polaris 250 Scrambler and anyone chasing a weak or intermittent spark.

Good To Know

Q: How do I know the sparkplug cap needs replacing? A: Cracks, a loose fit on the plug, or a corroded internal terminal are common signs, and a cap that arcs to the engine instead of through the plug will cause misfires. Q: Does the cap fit standard spark plug threads? A: The cap fits the plug terminal rather than the threads, so it works with the standard plug size used on the Polaris 250 Scrambler.

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