OE Fine Wire Double Platinum Product Line

The Bosch OE Fine Wire Double Platinum line features spark plugs with platinum on both the center and ground electrodes, enhancing durability and ignition stability. This design reduces electrode wear and maintains consistent spark performance over time, making it suitable for high-performance vehicles such as the Audi A4 Quattro and BMW 550i.

Technical Description and Benefits

The FR7KPP332 spark plug incorporates a platinum center electrode tip and a ground electrode tip composed of platinum combined with nickel-yttrium and copper. This combination improves electrode longevity and ensures stable ignition. The copper core in the ground electrode enhances thermal conductivity, helping to dissipate heat effectively. With a resistance of 6000 ohms, this spark plug reduces electrical noise interference, supporting optimal engine control module function. The ceramic insulator and non-projected design contribute to reliable insulation and consistent spark delivery. Its flat seat and 19 mm reach ensure proper fitment and sealing in compatible engines.

Installation Notes and Tips

Ensure the spark plug gap is set to the specified 1 mm pre-gap before installation. Use a 16 mm socket wrench to install the spark plug, tightening to the manufacturer’s torque specifications to avoid damage. Confirm the flat seat type matches the engine’s cylinder head design. It is recommended to replace all spark plugs simultaneously to maintain balanced engine performance. Avoid over-tightening to prevent thread damage.
