OE Fine Wire Double Iridium Product Line Details

The Bosch OE Fine Wire Double Iridium line focuses on delivering precise ignition performance through the use of fine wire electrodes and double iridium tips. This design reduces voltage requirements and enhances spark consistency, which is critical for modern 4-cycle engines found in many Audi, Porsche, and Volkswagen vehicles. The combination of iridium and platinum materials on the electrodes improves wear resistance and longevity compared to conventional spark plugs.

Technical Description and Benefits

The Bosch 96345 spark plug features a fine wire center electrode made of copper with an iridium tip, which allows for a more focused and efficient spark. The ground electrode uses a copper core with an iridium-platinum tip, providing durability and stable performance over time. The resistor built into the plug (6000 ohms) helps suppress electromagnetic interference, protecting sensitive vehicle electronics. The flat seat and 19 mm reach ensure proper fitment and sealing in compatible engines. This spark plug is designed for 4-cycle engines and is compatible with a wide range of Audi, Porsche, and Volkswagen models including the A3, A4, A5, A6, A7, A8, Beetle, Cayenne, Golf R, GTI, Jetta, Panamera, Passat, Q3, Q5, Q7, R8, RS5, S4, S5, SQ5, Tiguan, Touareg, TT, and TTS Quattro.

Common Applications and Issues Addressed

• Replacement for worn or fouled spark plugs in compatible Audi, Porsche, and Volkswagen vehicles
• Improves ignition stability and reduces misfires
• Helps restore engine smoothness and fuel efficiency
• Reduces electrical interference affecting onboard electronics
• Supports consistent combustion in 4-cycle engines

Installation Notes and Tips

Ensure the engine is cool before removing old spark plugs. Use a torque wrench to tighten the Bosch 96345 spark plug to the manufacturer’s recommended specifications to avoid damage. The 16 mm hex size allows for standard spark plug socket compatibility. Verify the pre-gap size of 0.7 mm before installation, adjusting if necessary to match vehicle requirements. The non-removable nut electrical terminal requires compatible ignition wires or coil packs.
