Details on Bosch OE Fine Wire Double Iridium Technology

The OE Fine Wire Double Iridium line from Bosch incorporates fine wire electrodes made from iridium and platinum-iridium alloys, which provide superior wear resistance and consistent spark quality. The center electrode core combines nickel-yttrium and copper to enhance conductivity and heat dissipation. This technology is designed to extend spark plug life and maintain stable ignition under various driving conditions, making it suitable for many GM and Ford vehicles.

Technical Specifications and Features

This spark plug features a tapered ground electrode tip and a standard ground configuration with one ground electrode, optimizing spark exposure and combustion efficiency. The 1.5 mm pre-gap size ensures reliable ignition timing. The ceramic insulator is non-projected, contributing to durability and heat resistance. With a thread diameter of 14 mm and a reach of 17.5 mm, the Bosch 9601 spark plug fits a wide range of engines including models like Chevrolet Silverado 1500, Ford Mustang, and Cadillac Escalade.

Applications and Common Issues Addressed

• Restores engine misfire and rough idle conditions
• Improves cold start performance in Buick and Pontiac vehicles
• Reduces spark plug fouling in Chevrolet and GMC trucks
• Enhances fuel efficiency and throttle response in Ford and Mercury models
• Supports consistent ignition in Cadillac and Oldsmobile engines

Installation Notes and Tips

Ensure the spark plug gap is set to 1.5 mm before installation if adjustment is necessary. Use a 16 mm socket wrench for proper torque application. Verify the tapered seat type matches the engine’s cylinder head design to prevent leaks. Avoid over-tightening to protect the ceramic insulator and threads. This spark plug is designed for 4-cycle engines and is not intended for outdoor power equipment.
