About the OE Fine Wire Double Iridium Product Line

The OE Fine Wire Double Iridium line from Bosch features spark plugs with fine wire electrodes made from iridium and platinum alloys. This combination provides a longer service life and stable spark delivery compared to conventional plugs. The double iridium design reduces electrode wear and maintains consistent ignition, making it suitable for demanding applications in 4-cycle engines found in many GM trucks and SUVs.

Technical Details and Specifications

This spark plug incorporates a nickel-yttrium and copper core center electrode with an iridium tip, paired with a platinum-iridium and nickel-yttrium ground electrode tip. The tapered seat and ground electrode tip design ensure a secure fit and efficient spark transfer. The ceramic insulator is projected to optimize heat control and prevent fouling. With a resistance of 6000 ohms, the built-in resistor minimizes radio frequency interference, protecting vehicle electronics.

Compatible Vehicles and Applications

• Chevrolet Silverado 1500, 1500 LD, 1500 LTD, 2500 HD, 3500 HD
• Cadillac Escalade and Escalade ESV
• GMC Sierra 1500, 1500 Limited, 2500 HD, 3500 HD
• GMC Yukon and Yukon XL
• Chevrolet Camaro, Corvette, Tahoe, Suburban 3500 HD

Common Issues Addressed by Bosch Spark Plug 96307

• Engine misfires and rough idling
• Reduced fuel efficiency due to incomplete combustion
• Difficulty starting the engine in cold conditions
• Increased emissions from inefficient spark delivery
• Premature electrode wear causing ignition instability

Installation Notes and Tips

Ensure the spark plug gap is set to the specified 0.9 mm before installation. Use a 16 mm socket wrench for proper torque application. The 25 mm reach and 14 mm thread diameter require matching cylinder head specifications. Avoid over-tightening to prevent thread damage. It is recommended to replace spark plugs in sets to maintain balanced engine performance.
