Detailed Product Features and Specifications

The Denso Iridium Power 5350 spark plug features an iridium center electrode tip, which offers a fine electrode for precise spark delivery and longer service life compared to conventional plugs. The copper core center electrode enhances thermal conductivity, helping to dissipate heat effectively. The ground electrode uses a nickel core with a tapercut, u-groove tip design to optimize spark exposure and combustion efficiency. This spark plug has a standard ground configuration with a single ground electrode, a pre-gap size of 1.1 mm, and a tapered seat type to ensure proper sealing and fitment.

With a thread diameter of 14.00 mm and a reach of 25.00 mm, the Denso 5350 is compatible with various engines requiring these dimensions. The hex size of 16.0 mm allows for straightforward installation using common tools. The manufacturer heat range of 20 indicates suitability for a wide range of operating conditions, balancing heat dissipation and fouling resistance. Additionally, the 5000 ohm resistance helps reduce electrical noise interference with vehicle electronics.
