Description
The NGK 3932 DCPR7E Nickel Spark Plug is engineered for dependable OE-style ignition performance, reliable starts, and consistent combustion. Built with a nickel alloy center electrode and a 98% pure copper core, this spark plug provides strong heat dissipation, conductivity, and durability across a wide range of operating conditions.
Designed for original equipment applications, the DCPR7E features a high-grade alumina silicate ceramic insulator for excellent dielectric strength and thermal performance. Triple gasket sealing helps prevent combustion gas leakage, while trivalent metal plating resists corrosion and seizing for easier installation and removal.
This is a solid replacement choice for engines originally equipped with standard nickel plugs and is well suited for select automotive and motorcycle fitments.
