The E3.70 auto spark plug is a 16mm, 0.860” reach plug with a taper seat. It fits Ford Triton applications from 2004 to 2008. E3.70 is a unique design that solves a problem with original OE application. The shell is made as a single piece, as opposed to two pieces, so it resists seizing in the engine and breaking apart when being removed. It is widely stocked in automotive retail stores. E3 automotive plugs have three legs securing the DiamondFIRE electrode to the shell. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. The patented DiamondFIRE side wire is proven to increase power, reduce fuel consumption and improve hydrocarbon emissions in long-term use. The unique ground electrode and full-size center electrode also provides optimal performance for a guaranteed five years or 100,000 miles. Part Number: E3.70; Resistor: Resistor; Hex Size: 5/8"; Thread Reach: 0.866"; Thread Diameter: 16mm; Seat: Taper; Tip/Gap: DiamondFIRE Fixed Gap Cannot Be Adjusted. 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 and garden spark plugs help engines operate more efficiently with a faster and smoother acceleration.
