About the OE Fine Wire Double Iridium Product Line

The Bosch OE Fine Wire Double Iridium line focuses on delivering spark plugs with fine wire electrodes made from iridium, a material known for its high melting point and wear resistance. This product line enhances ignition efficiency and longevity by combining iridium with platinum and nickel-yttrium alloys in the electrode tips. The 9617 spark plug benefits from this technology, providing consistent performance and durability in secondary ignition systems.

Technical Details and Features

The Bosch 9617 spark plug features a copper core ground electrode with a tapered tip design, improving electrical conductivity and heat transfer. The center electrode tip is made of iridium, while the ground electrode tip incorporates a platinum-iridium and nickel-yttrium-copper alloy, enhancing electrode life and spark stability. The spark plug’s 6000 ohm resistance helps suppress electromagnetic interference, protecting vehicle electronics. Its ceramic insulator is non-projected, contributing to reliable insulation and heat management. With a pre-gap size of 1.1 mm and a heat range of 8, this spark plug is optimized for 4-cycle engines found in compatible Buick, Cadillac, Chevrolet, GMC, Mazda, Pontiac, Saturn, and Suzuki models.
