4 pc DENSO 6023 W20MP-U Spark Plug
- CHOOSE CONSISTENT COMBUSTION: The DENSO Standard U-Groove Spark Plug employs a unique, channeled ground electrode designed to generate a larger spark nucleus at the point of ignition. Greater spark energy means improved flame travel, producing more complete, consistent, and efficient combustion. The electrode was developed to improve ignitability for increased efficiency in emission gas purification and fuel consumption
- IMPROVE THROTTLE RESPONSE: This spark plug fires leaner mixtures than conventional plugs and improves throttle response. The DENSO Standard U-Groove Spark Plug is 100 percent pre-fired to ensure reliable operation and lasts twice as long as conventional plugs. The unique five-rib insulator reduces flashover and decreases voltage loss while the dual copper and glass seal combines the center electrode and insulator together for a gas-tight seal
- RELY ON QUALITY AUTO PARTS: From the development of direct ignition coils to revolutionizing the concept of the aftermarket performance spark plug by using platinum and iridium, DENSO is often on the front lines of product advancement
- TRUST IN DENSO: The automotive industry has recognized the DENSO commitment to quality through such prestigious awards as the Deming Award for Quality, the J.D. Power and Associates Chairman's Award, and numerous supplier awards for quality
