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 platinum electrodes on both the center and ground electrodes. This design improves electrode longevity and provides a more consistent spark compared to conventional plugs. The double platinum construction reduces electrode wear, making it suitable for modern 4-cycle engines requiring precise ignition performance. The 8160 part number belongs to this line, ensuring compatibility with vehicles that demand OEM-level spark plug quality.

Technical Specifications and Features

The Bosch 8160 spark plug incorporates a center electrode made from platinum combined with nickel-yttrium and copper core materials, enhancing conductivity and durability. The ground electrode tip also uses platinum with nickel-yttrium and copper, maintaining consistent spark gap over time. The spark plug’s ceramic insulator is non-projected, providing effective heat dissipation and electrical insulation. With a flat seat and a reach of 26.5 mm, this plug fits securely in the combustion chamber. The resistor value of 1000 ohms helps suppress radio frequency interference, protecting vehicle electronics.
