OE Fine Wire Double Platinum Product Line Details

The OE Fine Wire Double Platinum line from Bosch features spark plugs with fine wire electrodes made of platinum on both the center and ground electrodes. This design improves wear resistance and ignition reliability compared to conventional plugs. The use of nickel-yttrium and copper in the center electrode core enhances conductivity, while the ceramic insulator ensures stable performance under high temperatures. This product line is tailored for vehicles requiring precise ignition components that meet original equipment specifications.

Technical Specifications and Features

The Bosch 8102 spark plug includes a 16 mm hex size and a tapered seat type, ensuring proper fit and sealing in compatible engines. The ground electrode tip and center electrode tip are both platinum, supported by nickel-yttrium materials for durability. The insulator is made from ceramic and is non-projected, contributing to reliable spark delivery. With a manufacturer heat range of 9, this spark plug is suitable for a variety of driving conditions. The resistor built into the plug helps minimize radio frequency interference, protecting vehicle electronics.

Compatible Vehicles and Applications

• Buick models such as Century, LaCrosse, and Regal
• Cadillac vehicles including Escalade and DeVille
• Chevrolet trucks and cars like Silverado 1500, Camaro, and Impala
• GMC models including Sierra 1500 and Yukon
