- 8 pc DENSO 5316 Spark Plug
- REDUCE EMISSIONS AND MISFIRES: The patented DENSO Spark Plug enables complete fuel ignition in the combustion chamber. It virtually eliminates erratic starts caused by poor fuel mixtures and excessive soot buildup. The DENSO Spark Plug employs a unique 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
- GAIN GREATER FUEL EFFICIENCY: This DENSO Spark Plug fires leaner mixtures than conventional plugs and improves throttle response. Its ground electrode was developed to improve ignitability for increased efficiency in emission gas purification and fuel consumption. The DENSO 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
- 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
