Description

The E3.62 Automotive Spark Plug is engineered for enhanced engine performance, aiming to increase power, reduce fuel consumption, and improve hydrocarbon emissions through its unique DiamondFIRE technology. This spark plug features a 14mm thread diameter, a 0.708" reach, and a taper seat, making it suitable for a range of domestic applications. It shares the same heat range as the E3.54 but is designed with a wider gap. The core of the E3.62's design is its DiamondFIRE electrode, secured by three legs to the shell. This construction promotes superior heat transfer and generates increased turbulence within the combustion chamber, contributing to more efficient burning. The plug also features a unique ground electrode and a full-size center electrode, which work together to deliver optimal performance. E3 guarantees optimal performance for this spark plug, providing a warranty of five years or 100,000 miles. The plug is a resistor type and has a fixed DiamondFIRE gap that cannot be adjusted. Its specifications include a 5/8" hex size and a 14mm thread diameter with a 0.708" reach and a taper seat. This spark plug primarily fits domestic applications. For specific vehicle fitment, it is recommended to use the vehicle finder tool, as compatibility can vary by make, model, and year.
