## Overview

The E3.48 Premium Spark Plug features patented DiamondFIRE technology with a 14mm, 0.750" reach and gasket seat, engineered to enhance engine power by up to 12%, improve fuel economy by up to 13%, and reduce emissions. Designed for broad domestic vehicle compatibility, it delivers long-lasting performance backed by a 5-year/100,000-mile warranty, making it the smart upgrade for professionals seeking reliable, eco-conscious engine efficiency.

## Description

The E3.48 auto spark plug is a high-performance 14mm, 0.750-inch reach plug with a gasket seat, designed to fit a wide variety of late model applications, particularly import vehicles. Known for its durability and performance. Featuring a unique design, it secures the patented DiamondFIRE electrode with three legs, allowing for excellent heat transfer and creating more turbulence within the cylinder for optimal combustion. The DiamondFIRE side wire is proven to increase engine power, reduce fuel consumption, and improve hydrocarbon emissions over long-term use. The plug's unique ground electrode and full-size center electrode ensure optimal performance, providing reliable results for up to five years or 100,000 miles. With a fixed gap design, the spark plug boasts a DiamondFIRE open structure that forces air gap discharges, creating a superior edge-to-edge spark path. This advanced design enables replenishment of the spark zone with a fresh fuel/air charge, exposing the flame front more directly to the piston head, which improves combustion efficiency. As a result, this spark plug increases engine power output, reduces gasoline consumption, decreases hydrocarbon and carbon monoxide emissions, and extends the spark plug’s lifespan. Perfect for lawn and garden equipment, it ensures faster, smoother acceleration and improved engine performance.
