E3.74
The E3.74 Automotive Spark Plug is a high-performance replacement plug designed for vehicle. Engineered with E3’s patented DiamondFIRE technology, the plug promotes a faster, more complete combustion cycle—boosting horsepower, increasing fuel efficiency, and reducing emissions over the long term. This spark plug features a 14mm thread diameter, 1.000" reach, and taper seat to ensure a precise fit for your vehicle engine. Its triple-legged ground electrode secures the DiamondFIRE tip, enhancing heat dissipation and generating greater turbulence in the combustion chamber for maximum efficiency. The fixed-gap design eliminates the need for adjustments and delivers consistent spark performance across thousands of miles. Backed by a 5-year or 100,000-mile warranty, the E3.74 offers durability and peak engine performance for drivers who demand more from their vehicle.
- Patented DiamondFIRE Technology: Optimizes combustion for better throttle response, horsepower, and fuel economy
- Three-Leg Ground Electrode: Stabilizes the electrode for enhanced heat transfer and increased combustion turbulence
- Fixed DiamondFIRE Spark Gap: Factory-set for consistent ignition and long-term reliability—no gapping required
- Extended Service Life: Built to perform for 100,000 miles or 5 years under typical driving conditions
- Precision Fit: 14mm thread diameter, 1.000" reach, 5/8" hex, taper seat design
- Lower Emissions: Reduces unburned hydrocarbons for cleaner, more efficient engine performance
