Detailed Product Description

The NGK Iridium IX Spark Plug 6853 features a copper core center electrode with an iridium tip, which provides a stable and efficient spark while maintaining electrode longevity. The taper cut ground electrode tip design enhances ignitability by reducing quenching effects, contributing to smoother engine starts and improved throttle response. The single nickel ground electrode offers durability and consistent performance under various operating conditions. This spark plug includes a removable nut electrical terminal type, allowing for easier installation and compatibility with different ignition systems.

With a pre-gap size of 0.032 inches and a flat seat type, the 6853 spark plug ensures proper spark gap and secure seating in the cylinder head. The 14mm thread diameter and 0.75 inch reach make it suitable for many vehicle engines requiring these specifications. The heat range of 9 is designed to manage combustion chamber temperatures effectively, preventing fouling and overheating.

About the Iridium IX Spark Plug Line
