Set of 2 pcs. polyurethane high-voltage wire pass-throughs for Ural, Dnepr, and K-750 motorcycles - an excellent replacement for standard rubber seals. The polyurethane pass-throughs route the high-voltage wire out of the distributor box cover to the spark plugs.

Why polyurethane is better than factory rubber:

• Chemical resistance: Completely unaffected by engine oil, gasoline, and road reagents.
• Thermal stability: Doesn't harden in freezing temperatures and doesn't "float" (soften/deform) from strong engine heat.
• Wear protection: The elastic and durable material prevents the ignition wire insulation from chafing against the sharp edges of the crankcase, protecting the ignition system from spark breakthrough to ground (shorting to ground).
