Designed specifically for Ford Triton engines (2004-2008), it features a 16mm thread, 0.860” reach, and taper seat for perfect fitment. Backed by a 5-year/100,000-mile warranty, it ensures long-lasting, eco-friendly performance that keeps your engine running smoother and cleaner. ## Description The E3.70 auto spark plug is a high-performance ignition component designed for Ford Triton applications from 2004 to 2008. With a 16mm thread diameter, 0.860-inch reach, and taper seat, this spark plug delivers optimal performance in automotive engines. E3 Spark Plugs are engineered with DiamondFIRE technology, a patented electrode design featuring three legs securing the DiamondFIRE electrode to the shell. This design improves heat transfer and creates more turbulence within the cylinder, promoting a more complete combustion process. The DiamondFIRE side wire enhances power, reduces fuel consumption, and lowers hydrocarbon emissions, making it a reliable and eco-friendly choice for long-term use. Features a unique ground electrode and full-size center electrode, ensuring the spark plug operates efficiently for up to five years or 100,000 miles. With a fixed gap design that cannot be adjusted, the DiamondFIRE open design facilitates air gap discharges, creating an edge-to-edge spark path that replenishes the spark zone with a fresh fuel/air charge. This results in more direct exposure of the flame front to the piston head, ultimately improving engine power output and fuel efficiency while reducing harmful emissions like carbon monoxide and hydrocarbons. ## 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 | |---------------|-------| | Brand | E3 | | Core Material | Copper | | Thread Size | values | | Top Material Type | Alloy Steel | | Vehicle Service Type | Car | | Global Trade Identification Number | 00894489000701, 00894489000800 | | Automotive Fit Type | Vehicle Specific Fit | | UPC | 894489000800 894489000701 | | OEM Part Number | E3.70 | | Manufacturer | E3 Spark Plugs | | Model | E3 Spark Plugs 4.3167G | | Item Weight | 2.08 ounces | | Product Dimensions | 4.78 x 1.5 x 1.6 inches | | Item model number | E3.70 | | Is Discontinued By Manufacturer | No | | Exterior | Per Item Description | | Manufacturer Part Number | E3.70 | | Position | Center | ## Product Details - **Brand:** E3 - **Core Material:** Copper - **Thread Size:** values - **Top Material Type:** Alloy Steel - **Vehicle Service Type:** Car ## Images ![Spark Plugs E3.70 Premium Automotive Spark Plug with DiamondFIRE Technology for Ford Applications, 16mm, 0.860” Reach, Taper Seat, Pack of 1 - Image 1](https://m.media-amazon.com/images/I/51szbej9jHL.jpg) ## Questions & Answers **Q: Anyone w/ 06 expedition or I guess any 5.4 liter ford has compared them with platinum or iridium doubles plasma? Im looking for performance** A: I own a 2006 Ford F150 5.4 these plugs is absolutely fantastic the power performers is greater the fuel mileage is great I recommend these plugs to anyone that owns 2006 Ford F150 or expedition **Q: Is this spark plug one one piece? The motor craft ones are 2 pieces that break when they are taken out.** A: Terrible luck with these. Kept loosing cylinder power due to the porcelain cracking. Pulled 2 out in less than 2 weeks then replaced them all. Went back to Motorcraft ones. **Q: I have a 2007 sport Trac v8 and bought these with a 5/8 socket but I can't get my old plugs out with the 5/8 so wondered if I need another size or if the one in my truck are different.** A: i know this is old but i'm answering to help others since i just figured this out last night. you want a 9/16 not a 5/8. **Q: is this spark plug colder than motorcraft sp515?** A: I believe they are the same. Be forewarned..I out them in my 2004 F150 with the 5.4L 3 valve. After about 1000 miles, I started having problems and intermittent CEL. I swapped coils around and just drove myself crazy. I ended up changing the plugs on a whim (last resort) and no more problem. I have put on over 5000 miles since I changed them out to the 515, and the truck runs great. ## Frequently Bought Together - E3 Spark Plugs E3.70 Premium Automotive Spark Plug w/DiamondFIRE Technology (Pack of 1) - ENA Set of 8 Straight Boot Ignition Coil Pack Compatible with Ford Lincoln Expedition Explorer F-150 Super Duty Mustang Mountaineer 4.6l 5.4l 6.8l Replacement for DG511 C1541 FD508 --- ## 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.hr/products/5936183-spark-plugs-e3-70-premium-automotive-spark-plug-with-diamondfire](https://www.desertcart.hr/products/5936183-spark-plugs-e3-70-premium-automotive-spark-plug-with-diamondfire) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-21*
