## Overview

The E3 Spark Plugs E3.58 is a premium automotive spark plug designed for domestic vehicles, featuring patented DiamondFIRE technology that enhances combustion efficiency, boosts power by up to 12%, and improves fuel economy by up to 13%. Built with durable materials and backed by a 5-year/100,000-mile warranty, it ensures long-lasting performance while reducing harmful emissions.

## Description

Product Description The E3.58 automotive spark plug is a high-performance solution designed for a variety of applications, particularly Jeep vehicles. Featuring a 14mm thread diameter and 0.750-inch reach, this spark plug includes an additional extension or skirt that extends the reach to 0.917 inches, making it suitable for a wide range of engine configurations. The patented DiamondFIRE side wire and unique three-leg design securely fasten the electrode to the shell, ensuring optimal heat transfer and creating increased turbulence in the combustion chamber. This design promotes a more complete burn, resulting in improved engine power, enhanced fuel efficiency, and reduced hydrocarbon emissions over long-term use. Includes a full-size center electrode and ground electrode, which together provide optimal performance, extending the life of the plug for up to five years or 100,000 miles. The DiamondFIRE technology delivers a preferred edge-to-edge spark path, efficiently replenishing the spark zone with a fresh fuel/air charge and exposing the flame front more directly to the piston head. This results in greater power output, reduced fuel consumption, and decreased emissions, all while ensuring a smoother and more efficient engine operation. Widely available in automotive retail stores and is a durable, long-lasting solution for those looking to enhance engine performance. desertcart.com

Review: Use in my '01 Jeep 4.0 - I know folks say just to use the standard plugs in the jeep 4.0 engine! However, I updated my ignition to the Viper style with wires and with the added voltage at the plug, these fit the bill perfectly. The coil and plug combo does make a noticeable difference in performance of this engine. Idles smoothly and just pulls better without that Pinto like bog between gears! 😂
Review: big increase in fuel mileage - great plug!!! first time i used this kind of plug and my fuel mileage went up 1 mile per gallon. i could not believe how smooth my car runs now. they are in a chrysler 300 (3.5). better spark = hotter burn=more power=less on the accelerator pedal= better fuel mileage. 0

### ⭐⭐⭐⭐⭐ Excellent for 1998 Dodge Durango 5.2L
*by J***L on June 15, 2024*

This is my second set for the 98 Durango. I bought some standard plugs from the local auto parts store a few weeks back and installed. They were not hot enough for the 5.2 and the vehicle did not run right. Installed the E3 again and it runs like a champ. I highly recommend these plugs.
