About this product
Maximize your engine's performance with the Denso IK16 Iridium Spark Plug. Engineered for demanding conditions and high performance, this spark plug delivers consistent ignition and enhanced efficiency.
Description
The Denso IK16 Iridium Spark Plug utilizes advanced technology to provide superior ignition performance. Featuring an iridium electrode that is six times harder than platinum and capable of withstanding temperatures up to 4,000°F, this spark plug ensures durability and longevity. The 0.4 mm iridium electrode reduces voltage requirements while improving firing performance. Its 360° laser-welded electrode provides a robust seal, resisting wear even under extreme conditions. The ground electrode is designed with a tapered cut and U-groove, creating a large volume area that centers the flame for a more complete and efficient burn. Upgrade to Denso Iridium spark plugs for improved throttle response, fuel economy, and overall engine performance. This resistor-type spark plug features a 14 mm thread size and a 19.1 mm (3/4") thread reach, making it compatible with a wide range of engines.
