Detailed Product Description

The Bosch OE Fine Wire Double Iridium Pin-to-Pin spark plug (part number 9693) is designed to meet original equipment specifications for secondary ignition systems. Its double iridium pin-to-pin ground electrode tip enhances spark efficiency and durability, while the iridium center electrode tip ensures a stable and long-lasting spark. The center electrode core combines nickel-yttrium and copper for optimal conductivity and heat dissipation. The ground electrode tip is constructed from a platinum-iridium and nickel-yttrium alloy, providing resistance to wear and corrosion.

This spark plug features a flat seat type and a 14mm hex size, facilitating proper fitment and torque application during installation. The 6000 ohm resistor integrated into the plug helps suppress radio frequency interference, protecting vehicle electronics. With a manufacturer heat range of 6 and a 1mm pre-gap size, it is tailored for efficient combustion in compatible Nissan and INFINITI 4-cycle engines.
