Details on Bosch OE Fine Wire Double Platinum Product Line

The OE Fine Wire Double Platinum line from Bosch features spark plugs with fine wire electrodes coated in platinum on both the center and ground electrodes. This design reduces electrode wear and maintains a stable spark over time, contributing to consistent engine performance and longer service intervals. The 8169 spark plug benefits from this technology, making it a reliable choice for BMW and Mini vehicles requiring precise ignition components.

Technical Description and Attributes

The Bosch 8169 spark plug incorporates a copper core ground electrode combined with platinum and nickel-chromium-iron tip materials to balance conductivity and durability. The center electrode uses a nickel-chromium-iron core with a platinum tip, enhancing ignition reliability. The ceramic projected insulator improves heat dissipation and electrical insulation, while the 6000 ohm resistor minimizes electromagnetic interference. With a flat seat and a 14mm hex size, this spark plug fits securely in compatible engines. Its 26.5mm reach and 0.8mm pre-gap size are optimized for the ignition systems of 4-cycle engines found in various BMW and Mini models.

Compatible Vehicles and Common Applications

• Designed for BMW models including 230i, 330i, 340i, 430i, 440i, 530i, 540i, 640i, 740i, and their xDrive variants
• Compatible with Mini Cooper, Cooper Clubman, Cooper Countryman, and M240i models
• Suitable for vehicles requiring spark plugs with a heat range of 5 and flat seat design
• Addresses ignition issues such as misfires, rough idling, poor fuel economy, hard starts, and reduced engine power

Installation Notes and Tips

• Ensure the spark plug gap is set to 0.8mm before installation if not pre-gapped
• Use a torque wrench to tighten the spark plug to manufacturer specifications to avoid damage
• Inspect the spark plug threads and cylinder head for debris or damage prior to installation
• Replace spark plugs in sets of six for BMW models requiring six plugs to maintain balanced engine performance
• Allow the engine to cool before removing or installing spark plugs to prevent thread damage
