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 ## Features - FOR DOMESTIC APPLICATIONS: Designed to fit a wide range of domestic vehicles, this spark plug enhances power, improves fuel economy, and reduces harmful hydrocarbon emissions, making it ideal for various engine types and models - DIAMONDFIRE TECHNOLOGY: Patented DiamondFIRE side-wire electrode design ensures a faster, more complete burn, optimizing combustion and improving engine efficiency for higher performance and reduced fuel consumption - MORE POWER AND FUEL EFFICIENCY: E3 Spark Plugs deliver up to 12% more power and up to 13% better fuel economy in small engines, and up mid-single digits on automotive applications, helping to enhance overall engine performance and reduce fuel consumption across a wide range of vehicles - LOWER EMISSIONS: The more complete burn helps to reduce emissions, minimize carbon buildup, promote cleaner combustion, and support compliance with modern environmental and emissions standards - LONG-LASTING PERFORMANCE: Built with Yttrium-enhanced alloy for durability and pre-ignition prevention; backed by a 5-year/100,000-mile limited warranty for reliable, extended use without frequent replacements ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | E3 | | Core Material | Copper | | Gap Size | 0.04 Inches | | Thread Size | 14mm | | Top Material Type | Alloy Steel | | Vehicle Service Type | Car | | Global Trade Identification Number | 00894489000589 | | Automotive Fit Type | Vehicle Specific Fit | | UPC | 894489000589 | | OEM Part Number | E3.58 | | Manufacturer | E3 Spark Plugs | | Model | Automotive Spark Plug | | Item Weight | 1.76 ounces | | Product Dimensions | 6.1 x 4.1 x 0.8 inches | | Country of Origin | China | | Item model number | E3.58 | | Is Discontinued By Manufacturer | No | | Exterior | Machined | | Manufacturer Part Number | E3.58 | ## Product Details - **Brand:** E3 - **Core Material:** Copper - **Gap Size:** 0.04 Inches - **Thread Size:** 14mm - **Top Material Type:** Alloy Steel ## Images ![Spark Plugs E3.58 Premium Automotive Spark Plug with DiamondFIRE Technology, 14mm Thread, 0.750-Inch Reach, Gasket Seat, Resistor, Pack of 1 - Image 1](https://m.media-amazon.com/images/I/41KLgG-MAvL.jpg) ## Questions & Answers **Q: How much speed, power, or economy does this increase?** A: Supposedly about 5hp.

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. ## Frequently Bought Together - E3 Spark Plugs E3.58 Premium Automotive Spark Plug with DiamondFIRE Technology, 14mm Thread, 0.750-Inch Reach, Gasket Seat, Resistor, Pack of 1 - E3 Spark Plugs E358 Spark Plug --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/10261225-spark-plugs-e3-58-premium-automotive-spark-plug-with-diamondfire](https://www.desertcart.it/products/10261225-spark-plugs-e3-58-premium-automotive-spark-plug-with-diamondfire) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-10*
