Designed with a colder heat range and Yttrium-enhanced alloy, it supports performance modifications while offering durability backed by a limited lifetime warranty. Compatible with a wide range of domestic trucks and vehicles, this spark plug ensures smoother acceleration and long-lasting reliability. ## Description The E3.62 auto spark plug is a 14mm, 0.708” reach plug with a taper seat. E3.62 is the same heat range as E3.54, but has a wider gap. It fits domestic applications, and is widely available in automotive retail stores. E3 automotive plugs have three legs securing the DiamondFIRE electrode to the shell. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. The patented DiamondFIRE side wire is proven to increase power, reduce fuel consumption and improve hydrocarbon emissions in long-term use. The unique ground electrode and full-size center electrode also provides optimal performance for a guaranteed five years or 100,000 miles. Part Number: E3.62; Resistor: Resistor; Hex Size: 5/8"; Thread Reach: 0.708"; Thread Diameter: 14mm; Seat: Taper; Tip/Gap: DiamondFIRE Fixed Gap Cannot Be Adjusted. Our unique DiamondFIRE open design forces air gap discharges, creating the preferred edge-to-edge spark path. The design allows replenishment of the spark zone with a fresh fuel/air charge, and exposes the flame front more directly to the piston head than other plug designs. This distinctive spark plug design has proven to simultaneously increase engine power output, reduce gasoline consumption, decrease hydrocarbon and carbon monoxide emissions from the engine, and materially extend the life of the spark plug. Our lawn and garden spark plugs help engines operate more efficiently with a faster and smoother acceleration. Review: Noticeable improvement but don't expect to blown away.... - desertcart sent me the wrong ones, I bought the right ones from a local brick and mortar. desertcart paid for the return and refunded my money. These are now the 3 set of these I have put in a car. This set went into a 3.1L 175hp Pontiac. Noticeable improvement in throttle response, and top end pull. BUT - don't expect to blown away. Combined with a Thrush baffled muffler, K&N drop in air filter, new OEM coils, and MSD 8.5mm plug wires, I probably netted +10% HP..... More impressive, my combined mileage has improved from 19.5mpg to 23.5mpg. Again, this is the combo of parts that achieved this, not the E3s alone.... For the mileage and meager performance increase, the full combo was well worth $300.... ***UPDATE*** 11.20.2020 I no longer own this car, but felt the need to update with other findings. Not all cars are happy with these. Most recently, a 2004 Grand Cherokee with the non-HO 4.7, responded poorly with rough idle and a top end that just felt off - like peak power started to roll off earlier. They were removed and factory spec copper plugs put back in. My 70 'Cuda was not happy either (340 stroked to 408, MSD distributorless ignition 6LS, Holly Dominator EFI). She has quite a bit of cam and already idles a touch rough. After the E3's she didn't want to idle at all despite attempts to tune the 6LS and Dominator systems to compensate. She was just plain angry. Never even bothered with a test drive. Autolite Platinums were installed. A 2000 Grand Caravan 3.0 v6 also suffered a poor idle, and actually saw an almost 1mpg loss. Autolite Platinums were installed. Review: 😳 they are Amazing ! In 350 vortec - So I purchased a crate motor 2 years ago from jugs automotive when I purchase the engine I purchased AC Delco iridium spark plugs from desertcart after engine installation and spark plug installation I developed a knocking and pinging noise I replaced the knock sensor and of course it already had the new plugs wires cap rotor and everything else under the hood I do know at the time where we get fuel changed the quality of gas for the winter I then started using premium fuel to stop the pinging at low rpm under load . Well well well . I went ahead and bought a set of E3 spark plugs oh my gosh throttle response amazing idle amazing no more pinging and the 5.7 runs amazing hard to believe the E3 changed the engine that much ! Some people say they have snake oil to sell you and e3's are a joke but I'm here to tell you they work phenomenal ## Features - Automotive spark plug that fits a variety of domestic applications, designed to increase power, reduce fuel consumption, and improve hydrocarbon emissions - E3's patented DiamondFIRE edge-to-edge electrode provides maximum performance with increased efficiency, and a faster more complete burn - Designed with colder heat ranges to enable performance modifications, and contains Yttrium-enhanced alloy for a reduction in side wire temperature for less pre-ignition - Includes one (1) E3.62 spark plug with a limited lifetime warranty - Primarily used in a wide variety of automotive and truck applications ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000BPOIBQ | | Automotive Fit Type | Vehicle Specific Fit | | Brand | E3 | | Brand Name | E3 | | Compatible with Vehicle Type | Truck | | Core Material | Copper | | Core material | Copper | | Customer Reviews | 4.5 out of 5 stars 371 Reviews | | Gap Size | 0.04 Inches | | Global Trade Identification Number | 00894489000626 | | Included Components | (1) Spark Plug | | Item Type Name | Spark Plugs | | Item Weight | 0.1 Pounds | | Manufacturer | E3 Spark Plugs | | Manufacturer Part Number | E3.62 | | Model Number | E3.62 | | Number of Items | 1 | | Number of Packs | 1 | | OEM Equivalent Part Number | E3.62 | | Top Material Type | Alloy Steel | | Top material type | Alloy Steel | | UPC | 894489000633 894489000626 | | Unit Count | 1.0 count | | Vehicle service type | Truck | ## Product Details - **Brand:** E3 - **Core material:** Copper - **Global Trade Identification Number:** 00894489000626 - **Top material type:** Alloy Steel - **Vehicle service type:** Truck ## Images ![E3 Spark Plugs E3.62 Premium Automotive Spark Plug w/DiamondFIRE Technology (Pack of 1) - Image 1](https://m.media-amazon.com/images/I/61fTI54b10L.jpg) ![E3 Spark Plugs E3.62 Premium Automotive Spark Plug w/DiamondFIRE Technology (Pack of 1) - Image 2](https://m.media-amazon.com/images/I/51LfIhJUiVL.jpg) ![E3 Spark Plugs E3.62 Premium Automotive Spark Plug w/DiamondFIRE Technology (Pack of 1) - Image 3](https://m.media-amazon.com/images/I/61MTw01T8jL.jpg) ![E3 Spark Plugs E3.62 Premium Automotive Spark Plug w/DiamondFIRE Technology (Pack of 1) - Image 4](https://m.media-amazon.com/images/I/61JqECLvSDL.jpg) ![E3 Spark Plugs E3.62 Premium Automotive Spark Plug w/DiamondFIRE Technology (Pack of 1) - Image 5](https://m.media-amazon.com/images/I/61snfdRfQJL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Noticeable improvement but don't expect to blown away.... *by W***2 on 20 April 2017* Amazon sent me the wrong ones, I bought the right ones from a local brick and mortar.

In 350 vortec *by D***D on 12 March 2022* So I purchased a crate motor 2 years ago from jugs automotive when I purchase the engine I purchased AC Delco iridium spark plugs from Amazon after engine installation and spark plug installation I developed a knocking and pinging noise I replaced the knock sensor and of course it already had the new plugs wires cap rotor and everything else under the hood I do know at the time where we get fuel changed the quality of gas for the winter I then started using premium fuel to stop the pinging at low rpm under load .

It happens all the time. The plugs have shown improvements in HP on a Dyno and have shown better mpg on some cars. As with anything else it is personal preference. simply put they will give a little plus in performance and mileage. Most people can't tell the difference because day to day drive varies. In racing even the smallest + in performance will be used. Every 10th of a second can make the difference between winning and losing. To the average Joe driving to work a few miles a day will not even notice and will more then likely say they didn't help. From what I seen is they put their foot in the gas more looking for more and end up using more gas. ## Frequently Bought Together - E3 Spark Plugs E3.62 Premium Automotive Spark Plug w/DiamondFIRE Technology (Pack of 1) - ACDelco Professional 9718Q Spark Plug Wire Set - Ignition Distributor Cap and Rotor Kit Compatible with Chevy GMC Cadillac Vortec V8 5.0l 5.7l 7.4l Ignition Distributor Set Brass Terminals with OE Part # DR474 DR331 --- ## 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.be/products/63225123-e3-spark-plugs-e3-62-premium-automotive-spark-plug-w](https://www.desertcart.be/products/63225123-e3-spark-plugs-e3-62-premium-automotive-spark-plug-w) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-18*
