"The E3. 18 lawn and garden spark plug is a 14mm, 0. 750-in. reach plug with a gasket seat designed for 4-cycle, overhead value small engine applications. Our E3. 18 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 N3C, N4C, N7YC, RN3C, RN4C, and RN7YC, and NGK B5EB, B6EB, B6ES, B6EV, B7EB, BR6EB, BR6ES, BR7EB, BUR6ES-11, and BUR7EB-11. 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 - Warranty: E3 lawn and garden spark plugs have a limited lifetime guarantee"

Works great and helps me run my generator longer than the older spark plug.

Now my PREDATOR 5000 Watt Dual-Fuel SUPER QUIET Inverter Generator starts on second pull or even with a weak battery. Very pleased.

I bought this for my Harbor Freight Predator generator. I have used it for a couple years and it was time for maintenance since it started misfiring. I bought this in hopes it would fix the issue and it worked great. In fact it doesn't sputter when it is really cold outside and it had done that since it was new. I would recommend the plug I purchased.

I've noticed I've used less gas since I installed these! Also it's easier to start my lawnmower.

Makes my small engines much easier to start.Snow blower, generator, back pack leaf blower, lawnmower, etc.Example : my brand new generator with a 457 cc OHV engine was taking 3 or 4 cranking tries to start when dead cold. Put in an E3, and now it starts the first crank.
