Its patented 360° laser welding guarantees exceptional durability, making it ideal for a wide range of vehicles including snowmobiles, UTVs, vans, and watercraft. This spark plug delivers enhanced combustion for more power and better fuel economy, backed by stellar user reviews and trusted OEM equivalence. ## 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 ### ⭐⭐⭐⭐⭐ Identique a l'origine *by N***S on 16 May 2026* C'est les mêmes que celles d'origine avec des performances au top.
