"The E3. 20 lawn and garden spark plug is a 14mm, 0. 750-in. reach plug with a gasket seat designed for 4-cycle, overhead valve engines. Our E3. 20 lawn & garden spark plug features the patented DiamondFIRE ground electrode, which provides greater power, better fuel efficiency, and dramatically lower hydrocarbon emissions. The electrode and full-size center electrode provides optimal performance over an extended product life. Replaces Champion plugs RC12YC and RC14YC, and NGK BCP4ES-11, BKR4E, BKR4E-11, BKR5E, BKR5E-11, BKRES, BKR6EKB-11, FR4, and FR5. Our unique DiamondFire open design forces air gap discharges, creating the preferred edge-to-edge spark path. The design allows replenishment of the spark zone with a fresh fuel/air charge, and exposes the flame front more directly to the piston head than other plug designs. This distinctive spark plug design has proven to simultaneously increase engine power output, reduce gasoline consumption, decrease hydrocarbon and carbon monoxide emissions from the engine, and materially extend the life of the spark plug. Our lawn & garden spark plugs help engines operate more efficiently with a faster and smoother acceleration. Key Features - Power increased > 6% to 12% (depending on engine class) - Fuel efficiency improved > 4% to 13% (depending on engine class) - Emissions reduced in 2 and 4-stroke engines (after 50 hours) - 58% CO emissions reduction, 42% hydrocarbon reduction

These plugs are a bit pricy, but work reliably in commercial mowing equipment.

These plugs have sold out locally because of hurricane season. I didn’t want to wait for them to come back in stock so ordered from Amazon. Came in a few days. They are for my generator. All that I had to do was screw off the end cap and they worked perfectly. Highly recommend!

I changed the plugs in three different lawn mowers. All three started much quicker and rn much stronger. Couldn't ask for much more.

Item is 3xs as much as competition. To return is the same amount as the over priced item. Will not deal with this company again. Scam
