Its Twin Tip technology minimizes spark quenching, delivering more complete combustion for enhanced engine power and fuel economy. Trusted by OEMs and backed by high customer ratings, this spark plug is a premium upgrade for vehicle performance and reliability. ## 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: Fantastic - Apparently they are the OEM manufacturer for spark plugs for Mazda. Probably other Japanese makers too. Fit perfectly and my car runs smoothly again. ## 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 | #700,275 in Automotive ( See Top 100 in Automotive ) #3,865 in Automotive Replacement Spark Plugs | | Brand | Denso | | Core Material | Iridium | | Customer Reviews | 4.6 4.6 out of 5 stars (429) | | Date First Available | February 16, 2015 | | Exterior | Machined | | Global Trade Identification Number | 00042511047112 | | Is Discontinued By Manufacturer | No | | Item Weight | 1.41 ounces | | Item model number | IXEH20TT | | Manufacturer | Denso | | Manufacturer Part Number | IXEH20TT | | Model | Denso Spark Plug | | OEM Part Number | DENS7 | | Position | Left | | Product Dimensions | 7.93 x 5.04 x 3.74 inches | | Thread Size | 12 millimeters | | Top Material Type | Metal | | UPC | 042511047112 | | 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 ![Iridium TT Spark Plug - 4711 (IXEH20TT) - Image 1](https://m.media-amazon.com/images/I/812UZ3IkwJL.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***S on August 9, 2024* Huge change in smoothness and performance great quality! ### ⭐⭐⭐⭐⭐ Fantastic *by C***R on April 16, 2024* Apparently they are the OEM manufacturer for spark plugs for Mazda.
