E3.74
The E3.74 Automotive Spark Plug is a high-performance ignition solution designed for vehicle engine. Built to handle the intense pressures and heat of high-horsepower applications, the E3.74 incorporates E3’s patented DiamondFIRE electrode technology to optimize combustion and spark efficiency.
The three-leg ground electrode design ensures maximum stability and superior heat transfer, creating more turbulence in the combustion chamber for a faster flame front and more complete fuel burn. This results in increased horsepower, improved throttle response, reduced fuel consumption, and lower emissions—critical for both performance and efficiency in high-output engines.
The E3.74 features a 14mm thread diameter, 1.000” reach, and a tapered seat for secure, high-pressure sealing. With a fixed DiamondFIRE gap, 5/8" hex, and resistor for radio interference suppression, it installs easily and lasts long, offering up to 100,000 miles or 5 years of dependable service in even the most demanding environments.
