## Description

Product Description The E3.20 lawn and garden spark plug is designed for 4-cycle, overhead valve engines and features a 14mm, 0.750-inch reach with a gasket seat. Engineered to enhance performance, the spark plug utilizes the patented DiamondFIRE ground electrode to deliver superior power, improved fuel efficiency, and significantly reduced hydrocarbon emissions. The advanced design includes a full-size center electrode for optimal long-term performance, ensuring extended product life. This spark plug replaces several Champion and NGK plugs, including Champion RC12YC, RC14YC, and NGK BCP4ES-11, BKR4E, and others. The unique DiamondFIRE open design generates air gap discharges, creating an edge-to-edge spark path that helps to replenish the spark zone with a fresh fuel/air charge. This design directly exposes the flame front to the piston head, contributing to improved combustion. Proven to boost engine power output by 6% to 12%, depending on the engine class, while also enhancing fuel efficiency by 4% to 13%. After 50 hours of operation, it achieves a 58% reduction in CO emissions and a 42% reduction in hydrocarbons, making it an environmentally friendly choice for your lawn and garden equipment. Our spark plug ensures faster, smoother acceleration and more efficient engine operation for a variety of lawn and garden engines. desertcart.com
