Bosch 8107 Spark Plug

Bosch OE Fine Wire Double Platinum Spark Plug 8107

Bosch 8107 is an OE Fine Wire Double Platinum spark plug built for direct replacement service in a wide range of GM, Buick, Cadillac, GMC, Saturn, Pontiac, Saab, Hummer, and Isuzu applications. It uses platinum on the center electrode and platinum in the ground electrode inlay to help reduce gap erosion and maintain stable performance over time.

Key Features

• OE Fine Wire Double Platinum design for OE-style ignition performance
• Platinum center electrode tip for durability and consistent spark delivery
• Platinum ground electrode inlay to reduce wear at the gap
• Preset 1.1 mm gap; do not gap before installation on listed applications
• Resistor plug with 6000 ohm resistance
• Tapered seat, 14 mm thread diameter, 25 mm reach, 16 mm hex
• Ceramic insulator with non-projected tip design

Product Details

The Bosch OE Fine Wire Double Platinum line is built around OE spark plug technology, using platinum at both the firing point and the ground electrode contact area. That construction helps control electrode wear and supports long service life in engines that call for a double platinum spark plug. Bosch 8107 is a direct-fit ignition service part for vehicles such as Chevrolet Colorado, Chevrolet Malibu, GMC Canyon, Buick Envision, and Cadillac ATS where the factory specification calls for this style of plug. The part number 8107 is also a useful reference when ordering for GM-based platforms that require a preset-gap platinum plug.

Common Problems This Spark Plug Can Address

• Hard starting caused by worn or eroded spark plug electrodes
• Rough idle from inconsistent ignition performance
• Misfire codes related to plug wear or incorrect plug type
• Reduced fuel economy from weak or unstable spark delivery
• Service issues on engines that require a preset-gap double platinum plug

Installation Notes and Tips

• Verify engine application by year, make, and model before installation.
• Do not gap this plug on applications marked “Do Not Gap, Gap is Preset.”
• Use the specified torque and follow the vehicle service manual for ignition service.
• Inspect coil boots and ignition components during spark plug replacement.
• Confirm the tapered seat and 14 mm thread specification match the original plug.

Quality Assurance

Bosch manufactures this spark plug to meet Original Equipment specifications for double platinum applications. The platinum firing pin and platinum ground inlay are used to improve wear resistance and maintain performance characteristics over the service interval.
