Its Twin Tip Technology enables omni-directional sparks that maximize combustion efficiency, delivering more power and better fuel economy. Universally compatible with multiple vehicle types, this spark plug is a top-rated choice for professionals seeking reliable, high-performance ignition. ## 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.

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 ### ⭐⭐⭐⭐⭐ La calidad del producto *by A***Z on 4 March 2024* Excelente calidad, es lo que buscamos los clientes, de verdad que se nota el cambio en el desempeño del auto, de usar bujias convencionales, a las de Iridium originales. Estoy muy contento con el producto. ### ⭐⭐⭐⭐⭐ Exactly what I needed! Delivered fast with good customer service! *by R***B on 15 November 2019* ### ⭐⭐ Conforme mais très mal emballé. *by X***R on 9 January 2026* Produit conforme, mais emballage et livraison chaotique. Les bougies étaient sorties de leur emballage, ne garantissant pas leur fonctionnement. Elles ont pu s'entrechoquer avec la porcelaine. La partie IRIDIUM est quand à elle protégé par une partie en plastique. Il ne devrait pas y avoir de problème sur cette partie. Experience mauvaise car pièce stratégique dans un moteur. Crainte de casse de la partie porcelaine sur la longueure. ## 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.fr/products/439739167-iridium-tt-spark-plug-4711-ixeh20tt](https://www.desertcart.fr/products/439739167-iridium-tt-spark-plug-4711-ixeh20tt) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-04-22*
