About this product
Maximize your engine's performance with the Denso IK20 Iridium Spark Plug. Engineered for superior ignition and longevity, this spark plug provides reliable starts and optimized combustion.
Description
The Denso IK20 Iridium Spark Plug utilizes advanced technology to deliver exceptional performance. Its iridium electrode, six times harder than platinum and capable of withstanding temperatures up to 4,000°F, ensures durability and consistent spark. The ultra-fine 0.4mm iridium electrode reduces voltage requirements while significantly improving firing performance. The 360° laser welding creates an airtight seal that withstands extreme conditions, preventing wear and ensuring long-lasting reliability. Furthermore, the ground electrode features a tapered cut and U-groove design, creating a large volume area that enhances flame propagation, leading to more efficient combustion and increased power. Upgrade to Denso Iridium spark plugs for enhanced engine response, improved fuel efficiency, and reduced emissions. The IK20 spark plug features a 14mm thread size, 19.1 mm (3/4") thread reach and a 16 mm (5/8") hex size.
