وصف
The E3.40 auto spark plug is designed for domestic applications from the 1960s to the early 1990s, featuring a 14mm thread diameter and a 0.460” reach with a taper seat. This spark plug is known for its durability and performance in older vehicle models. E3's innovative three-leg design secures the DiamondFIRE electrode to the shell, ensuring excellent heat transfer and increasing turbulence within the cylinder. This results in more efficient combustion and a more complete burn. The patented DiamondFIRE side wire technology is proven to boost engine power, reduce fuel consumption, and improve hydrocarbon emissions. Additionally, the unique ground electrode and full-size center electrode provide optimal performance and reliability, guaranteeing up to five years or 100,000 miles of use. The plug's DiamondFIRE open design forces air gap discharges, creating a preferred edge-to-edge spark path. This design facilitates the replenishment of the spark zone with a fresh fuel/air charge and exposes the flame front more directly to the piston head, enhancing combustion efficiency. As a result, the spark plug delivers increased power output, better fuel efficiency, reduced carbon monoxide and hydrocarbon emissions, and a longer lifespan, making it an excellent choice for domestic vehicles and lawn and garden engines.
