The SK20R11 spark plug is an iridium-tipped plug designed for use in various gasoline-powered engines. It is part of Denso’s Iridium Power series of spark plugs, which are engineered to provide high performance and long-lasting durability.
The SK20R11 spark plug features a 0.4mm diameter iridium center electrode, which allows for a stronger spark and improved combustion efficiency. The iridium alloy used in the electrode is also highly resistant to wear and corrosion, which helps to extend the plug’s lifespan.
The plug also has a tapered cut ground electrode, which helps to improve ignitability and fuel efficiency. The electrode design also helps to reduce the risk of fouling, which can occur when deposits build up on the plug’s surface and inhibit spark performance.
The SK20R11 spark plug is compatible with a wide range of vehicle makes and models, and is designed to provide reliable performance and fuel efficiency in a variety of driving conditions.
