Details on Bosch OE Fine Wire Double Iridium Technology

The OE Fine Wire Double Iridium line from Bosch features spark plugs with fine wire iridium center electrodes combined with platinum-iridium ground electrode tips. This combination improves ignition reliability and electrode longevity compared to conventional plugs. The center electrode core is made from nickel-yttrium and copper, enhancing conductivity and heat dissipation. The ground electrode uses a copper core with a platinum-iridium and nickel-yttrium alloy tip, providing stable spark formation and resistance to wear. These design elements contribute to consistent engine performance and reduced misfires in compatible vehicles.

Common Issues Addressed by Bosch Spark Plug 96306

• Engine misfires and rough idling
• Poor fuel efficiency due to incomplete combustion
• Difficulty starting the engine in cold conditions
• Reduced engine power and acceleration
• Increased emissions from inefficient ignition

Installation Notes and Tips

Before installation, verify the spark plug gap is set to the specified 0.7 mm pre-gap. Use a 16 mm socket wrench for proper tightening to avoid damage. Ensure the spark plug threads match the engine specifications with a 14 mm diameter and 19 mm reach. The resistor design helps reduce electrical interference with onboard electronics, so use as a direct replacement for original equipment plugs. Avoid over-tightening to prevent thread damage or improper sealing.
