Details on the Iridium Power Product Line

The Iridium Power line by Denso focuses on delivering spark plugs with iridium-tipped electrodes that provide a balance of durability and ignition efficiency. This product line is designed to improve ignition performance and longevity compared to conventional spark plugs, making it suitable for high-performance vehicles such as Ferrari models requiring precise ignition timing and stable combustion.

Technical Description of the Spark Plug

The Denso 5362 spark plug features a copper core center electrode with an iridium tip, which enhances electrical conductivity and wear resistance. The ground electrode uses a nickel core with a tapercut, u-groove tip design to optimize spark exposure and combustion efficiency. The flat seat ensures a secure fit in the cylinder head, while the 19.00 mm reach and 14.00 mm thread diameter match the specifications required by Ferrari 360, F355 Berlinetta, and GTO engines. The 0.9 mm pre-gap size is factory set to maintain consistent spark performance, and the 5000 ohm resistance helps minimize electromagnetic interference with vehicle electronics.
