About this product

Description
The Denso IW16 Iridium Spark Plug uses advanced technology to provide exceptional performance. Its iridium electrode, six times harder than platinum, can withstand temperatures up to 4,000°F (2,200°C). The ultra-fine 0.4 mm iridium electrode reduces voltage requirements and improves firing performance. The 360° laser welding creates a robust seal, resisting wear and tear. The ground electrode features a tapered cut and U-groove design, creating a large volume area that optimizes flame propagation, resulting in a more complete and efficient combustion. This resistor-type spark plug is designed for easy installation with its threaded stud terminal configuration and 14 mm thread size.
