Product Description

"Our E3.42 automotive spark plug is a 14mm, 0.460-in. reach plug with a taper seat designed for a variety of 1980's to early 1990's domestic applications. Our E3.42 auto spark plug features the patented DiamondFIRE ground electrode, which provides greater power, faster starts, better fuel efficiency, and lower emissions in long-term use. The electrode is secured to the shell with 3 legs to help facilitate excellent heat transfer, and to create more turbulence in the cylinder. The E3.42 will help your vehicle operate more efficiently using the latest technologies.
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 automotive spark plugs help engines operate more efficiently with a faster and smoother acceleration.
Key Features
- Power increased > 4% to 6% (depending on engine class)
- Fuel efficiency improved > 4% to 5% (depending on engine class)
- Reduced emissions
- Warranty: E3 automotive spark plugs come with a 5-year/ 100,000-mile warranty"
