NGK Spark Plug Cap

NGK resistor covers feature a 5K ohm resistor element constructed of high quality ceramic material, designed long enough to prevent interior flashover, and yet maintain constant resistance, with only slight variation under over-load conditions.

FEATURES

• The cover body is made of sturdy phenolic resin that endures high heat and high tension.
• The rugged special rubber liners on both ends prevent moisture from causing electrical leakage.
• Combined usage of the resistor covers and resistor spark plugs is more efficient to suppress ignition noise from engines in motorcycles, snowmobiles, farm tractors and so on.
