OE Fine Wire Double Iridium Pin-to-Pin Product Line Details

The OE Fine Wire Double Iridium Pin-to-Pin line from Bosch features spark plugs with dual iridium electrodes designed to enhance ignition reliability and durability. The pin-to-pin ground electrode tip design improves spark consistency, while the use of iridium and platinum-iridium materials on the electrodes ensures long service life and stable performance. This product line is tailored for vehicles requiring precise ignition components that meet original equipment specifications.

Technical Description and Features

The Bosch 96309 spark plug incorporates a copper core ground electrode combined with a platinum-iridium and nickel-yttrium alloy tip, optimizing conductivity and wear resistance. The center electrode uses a nickel-yttrium and copper core with an iridium tip, providing a fine wire design that supports efficient spark generation. The 6000 ohm resistor reduces electrical noise interference, protecting vehicle electronics. With a flat seat type and a 1 mm pre-gap, this spark plug is engineered for consistent ignition in 4-cycle engines. Its 16 mm hex size and 14 mm thread diameter ensure compatibility with specified Acura, Honda, and Lexus models.
