Denso W27esru U-groove Spark Plug

The Denso W27ESRU U-Groove Spark Plug delivers exceptional performance and reliability for your engine. Manufactured by Denso, a trusted original equipment supplier, this spark plug ensures optimal combustion and efficient operation, improving overall engine performance and fuel economy.

Description

The Denso W27ESRU spark plug features a copper core center electrode that provides superior thermal conductivity, efficiently dissipating heat and preventing overheating. The unique five-rib insulator design reduces flashover and minimizes voltage loss, ensuring a consistent and powerful spark. Its dual copper and glass seal creates a gas-tight bond between the center electrode and insulator, preventing leaks and maintaining optimal compression. The U-Groove ground electrode enhances ignitability, leading to improved combustion efficiency and reduced emissions. This resistor-type spark plug is designed for dependable performance in demanding conditions and is an excellent choice for enthusiasts and professionals alike. With a 14 mm thread size and 19.1 mm (3/4") thread reach, installation is straightforward and ensures a secure fit.
