Its Twin Tip technology enables omni-directional sparks that maximize combustion efficiency, delivering enhanced power and fuel economy. Designed for cars and trucks, this premium spark plug offers a precise fit and long-lasting performance, making it a top choice for drivers seeking smooth, efficient engine operation. ## Description Iridium TT Twin Tip Technology delivers far less obstruction to the spark allowing an Omni-directional explosion. This minimizes the quenching effect and results in a more effective, more complete combustion. Better combustion means more power and better fuel economy, as fuel is burned more efficiently with each piston firing. The large center and ground electrodes seen on a Standard Plug increases "quenching" of the explosion, meaning the spark explosion is restricted by the electrodes above and below the gap, allowing it to spread to either side, but not grow with full range. Review: Great plugs - Huge change in smoothness and performance great quality! Review: use anti-seize - The Denso and equivalent Bosch plugs are essentially identical in terms of performance. The decision on which to buy simply which is cheaper. The one aspect to keep in mind, apply a very small dab of an anti seize compound to the leading edge of the threads. This is cheap insurance in that the plug can be taken out without damaging the threads in the head. ## Features - Denso 4711 - 0.4mm Iridium Center Electrode - 0.7mm Platinum Ground Electrode - Larger spark translates to more power and superior fuel economy - 0.4 mm iridium center electrode: world's smallest diameter that maximizes firing potential.0.7 mm needle tip ground electrode: promotes higher spark energy and less heat quenching.DENSO patented 360 degree laser welding process: ensuring exceptional quality bond and structural strength with the iridium center electrode - 0.4 mm iridium center electrode: world's smallest diameter that maximizes firing potential - 0.7 mm needle tip ground electrode: promotes higher spark energy and less heat quenching - DENSO patented 360 degree laser welding process: ensuring exceptional quality bond and structural strength with the iridium center electrode ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00TPUAJIY | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #959,855 in Automotive ( See Top 100 in Automotive ) #4,806 in Automotive Replacement Spark Plugs | | Brand | Denso | | Brand Name | Denso | | Compatible with Vehicle Type | Car, Truck | | Core Material | Iridium | | Customer Reviews | 4.6 out of 5 stars 451 Reviews | | Global Trade Identification Number | 00042511047112 | | Included Components | Spark Plug | | Item Type Name | Spark Plug | | Item Weight | 40 g | | Manufacturer | Denso | | Manufacturer Part Number | IXEH20TT | | Manufacturer Warranty Description | Part | | Model Number | IXEH20TT | | OEM Equivalent Part Number | DENS7 | | Thread Size | 12 millimeters | | Top Material Type | Metal | | UPC | 042511047112 | | Unit Count | 1 Count | | Vehicle Service Type | Car, Truck | ## Product Details - **Brand:** Denso - **Core Material:** Iridium - **Thread Size:** 12 millimeters - **Top Material Type:** Metal - **Vehicle Service Type:** Car, Truck ## Images ![Denso Iridium TT Spark Plug - 4711 (IXEH20TT) - Image 1](https://m.media-amazon.com/images/I/812UZ3IkwJL.jpg) ![Denso Iridium TT Spark Plug - 4711 (IXEH20TT) - Image 2](https://m.media-amazon.com/images/I/51lRULUtc5L.jpg) ![Denso Iridium TT Spark Plug - 4711 (IXEH20TT) - Image 3](https://m.media-amazon.com/images/I/61DTbCFzBBL.jpg) ![Denso Iridium TT Spark Plug - 4711 (IXEH20TT) - Image 4](https://m.media-amazon.com/images/I/61RS0rwODCL.jpg) ![Denso Iridium TT Spark Plug - 4711 (IXEH20TT) - Image 5](https://m.media-amazon.com/images/I/61mlMQvCKzL.jpg) ## Questions & Answers **Q: does this has 0.004 size difference? is it issue ? oem is 0.004** A: If you are driving a Mazda Skyactive engine newer than 2012, you should be o.k.. In 2012, the stock Skyactive 2.0 uses the OEM spark plug with 0.032 gap, then the Mazda revised the spec to 0.040 gap for the vehicle after 2013. The newest spec is 0.044. The older 4711 spark plug has 0.032 then I just notice it is now 0.040. As long as your car is updated with the latest Mazda software, you should be o.k.. Personal note, this Denso 4711 burns better in my opnion and it is cheaper too. **Q: work to nissan versa 2009? engine 1.8** A: According to their website, yes.http://densoautoparts.com/find-my-part/vehicle-selectionAssuming it's the s-1.8L engine. **Q: Hola son compatibles para un Toyota Corolla 2016?** A: Si **Q: Would it fit corolla 1.6l 2011?** A: There was no 1.6L engine offered for a 2011 Toyota Corolla so I assume you have a 1.8L engine which would take Denso IXEH20TT or Denso SC20HR11 (Iridium Long Life). ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great plugs *by R***T on August 9, 2024* Huge change in smoothness and performance great quality! ### ⭐⭐⭐⭐⭐ use anti-seize *by L***N on June 27, 2026* The Denso and equivalent Bosch plugs are essentially identical in terms of performance. The decision on which to buy simply which is cheaper. The one aspect to keep in mind, apply a very small dab of an anti seize compound to the leading edge of the threads. This is cheap insurance in that the plug can be taken out without damaging the threads in the head. ### ⭐⭐⭐⭐⭐ Fantastic *by C***R on April 16, 2024* Apparently they are the OEM manufacturer for spark plugs for Mazda. Probably other Japanese makers too. Fit perfectly and my car runs smoothly again. ## Frequently Bought Together - Denso (4711) IXEH20TT Iridium TT Spark Plug, (Pack of 1) - Denso 143-3005 Air Filter - Genuine Toyota 04152-YZZA6 Replaceable Oil Filter Element --- ## 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.pt/products/26672115-denso-iridium-tt-spark-plug-4711-ixeh20tt](https://www.desertcart.pt/products/26672115-denso-iridium-tt-spark-plug-4711-ixeh20tt) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-08*
