About this product
The Denso W20EPU U-Groove spark plug delivers exceptional performance and reliability for your engine. Featuring advanced technology and high-quality materials, this spark plug ensures efficient combustion and consistent ignition.
Description
Denso's W20EPU spark plug is engineered for superior thermal conductivity and reliable operation. The copper core center electrode efficiently dissipates heat, preventing overheating and ensuring consistent spark. Its unique five-rib insulator minimizes flashover, reducing voltage loss and optimizing ignition performance. The dual copper and glass seal creates a gas-tight bond between the center electrode and insulator, preventing leaks and maintaining optimal combustion. This non-resistor type spark plug with a 14 mm thread size and 19.1 mm (3/4") thread reach is designed to meet or exceed original equipment standards. The U-Groove ground electrode enhances ignitability and reduces quenching, resulting in a more powerful and efficient combustion process. Upgrade to Denso spark plugs for improved engine performance, fuel efficiency, and longevity. Trust Denso for quality and performance; used as Original Equipment in many automotive applications.
