Denso W27ES-U U-Groove Spark Plug

The Denso W27ESU U-Groove Spark Plug delivers reliable ignition and consistent performance for your engine. Engineered with precision and built to meet or exceed OE standards, this spark plug ensures optimal combustion and efficient operation. Experience smoother starts, improved throttle response, and enhanced fuel efficiency with Denso's advanced spark plug technology.

Description

Denso's W27ESU spark plug features a copper core center electrode that provides superior thermal conductivity, effectively dissipating heat and preventing pre-ignition. The unique five-rib insulator design minimizes flashover, reducing voltage loss and ensuring a strong, consistent spark. A 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 by allowing the spark to expand freely, resulting in more complete combustion. This spark plug is pre-fired to guarantee reliable performance right out of the box, ensuring a hassle-free installation and long-lasting durability. Trust Denso's reputation for quality and innovation to keep your engine running smoothly.
