Compatible with a broad range of late-model domestic and import vehicles, it promotes cleaner combustion to reduce emissions and carbon buildup. Backed by a 5-year/100,000-mile warranty, this spark plug ensures long-lasting, reliable performance for professional-grade driving efficiency. ## Description The E3.80 auto spark plug is engineered for high performance in a wide range of late-model applications, particularly imports. Featuring a 12mm thread diameter, 1.000-inch reach, and gasket seat, this spark plug offers exceptional compatibility and reliable operation. Utilizes E3's patented DiamondFIRE technology, where two legs secure the DiamondFIRE electrode to the shell, ensuring superior heat transfer and helping to create additional turbulence within the cylinder for more efficient combustion. The DiamondFIRE side wire is scientifically proven to boost engine power, reduce fuel consumption, and lower hydrocarbon emissions over the long term. The spark plug's fixed gap design cannot be adjusted, but the DiamondFIRE open design allows air gap discharges, creating a preferred edge-to-edge spark path. This process replenishes the spark zone with a fresh fuel/air charge, resulting in improved combustion efficiency and more direct exposure of the flame front to the piston head. As a result, the E3.80 spark plug not only increases engine power output but also improves fuel efficiency, reduces gasoline consumption, and decreases carbon monoxide and hydrocarbon emissions. Ideal for both import and late-model vehicles, the E3.80 spark plug enhances engine performance. ## 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 side-wire electrode delivers a faster, more complete burn, producing up to 4%-12% more power and up to 3%-13% better fuel economy depending on engine class - 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 - VERSATILE COMPATIBILITY: Widely used in various automotive and truck models, delivering improved power output, smoother acceleration, and reduced fuel consumption across many engine types - LONG-LASTING PERFORMANCE: Includes a 5-year/100,000-mile limited warranty for long-lasting use and dependable performance without frequent replacements ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07B6PPDJR | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #1,491,722 in Automotive ( See Top 100 in Automotive ) #7,066 in Automotive Replacement Spark Plugs | | Brand | E3 | | Brand Name | E3 | | Compatible with Vehicle Type | Car | | Core Material | Copper | | Customer Reviews | 4.3 out of 5 stars 300 Reviews | | Gap Size | 0.04 inches | | Global Trade Identification Number | 00857661006809 | | Included Components | (1) Automotive Spark Plug | | Item Type Name | E3 Spark Plugs E3.80 Automotive Spark Plug | | Item Weight | 1.6 ounces | | Manufacturer | E3 Spark Plugs | | Manufacturer Part Number | E3.80 | | Manufacturer Warranty Description | E3 Automotive spark plugs are warranted to be free of defects in material and workmanship for a limited 5 years or 100,000 miles from the date of purchase. | | Model Number | E3.80 | | Number of Items | 1 | | Number of Packs | 1 | | OEM Equivalent Part Number | E3.80 | | Thread Size | 12mm | | Top Material Type | Alloy Steel | | UPC | 857661006809 | | Unit Count | 1 Count | | Vehicle Service Type | Car | ## Product Details - **Brand:** E3 - **Core Material:** Copper - **Thread Size:** 12mm - **Top Material Type:** Alloy Steel - **Vehicle Service Type:** Car ## Images ![E3 Spark Plugs E3.80 Premium Automotive Spark Plug with DiamondFIRE Technology, 12mm, 1.000” Reach, Gasket Seat, Compatible with Late Model Import Applications, Pack of 1 - Image 1](https://m.media-amazon.com/images/I/71DVrwCJBoL.jpg) ![E3 Spark Plugs E3.80 Premium Automotive Spark Plug with DiamondFIRE Technology, 12mm, 1.000” Reach, Gasket Seat, Compatible with Late Model Import Applications, Pack of 1 - Image 2](https://m.media-amazon.com/images/I/61xTB0h2jzL.jpg) ![E3 Spark Plugs E3.80 Premium Automotive Spark Plug with DiamondFIRE Technology, 12mm, 1.000” Reach, Gasket Seat, Compatible with Late Model Import Applications, Pack of 1 - Image 3](https://m.media-amazon.com/images/I/51aIjpgFExL.jpg) ![E3 Spark Plugs E3.80 Premium Automotive Spark Plug with DiamondFIRE Technology, 12mm, 1.000” Reach, Gasket Seat, Compatible with Late Model Import Applications, Pack of 1 - Image 4](https://m.media-amazon.com/images/I/41QXAE5uB+L.jpg) ![E3 Spark Plugs E3.80 Premium Automotive Spark Plug with DiamondFIRE Technology, 12mm, 1.000” Reach, Gasket Seat, Compatible with Late Model Import Applications, Pack of 1 - Image 5](https://m.media-amazon.com/images/I/61ooH7LXpuL.jpg) ## Frequently Bought Together - E3 Spark Plugs E3.80 Premium Automotive Spark Plug w/DiamondFIRE Technology (Pack of 1) - DrCax OEM Ignition Coil UF764 GN10730 Compatible with Genesis Kia G70 G80 G90 Santa Fe Sonata Optima Sorento Sportage Stinger Replaces 27300-2GGA0 E1264 IC871-2.0L 2.4L L4-1 Pack --- ## 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.ie/products/102115578-e3-spark-plugs-e3-80-premium-automotive-spark-plug-diamondfire](https://www.desertcart.ie/products/102115578-e3-spark-plugs-e3-80-premium-automotive-spark-plug-diamondfire) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-09-21*
