Bosch OE Fine Wire Double Platinum Spark Plug 8106

Bosch 8106 is an OE Fine Wire Double Platinum spark plug built for steady ignition performance and extended service life. It uses platinum on the center electrode and a platinum inlay on the ground electrode to reduce gap erosion and maintain consistent firing over time.

Compatible With select Buick Century, Chevrolet Lumina, Pontiac Grand Prix, and other GM applications listed below, this Bosch spark plug follows original equipment specifications for double platinum designs. The preset gap means no gapping is required before installation.

Product Details

Bosch OE Fine Wire Double Platinum spark plugs are engineered around OE spark plug technology, using platinum at both the firing point and the ground electrode contact area to help limit wear. That construction supports consistent ignition characteristics and longer service intervals in applications that call for a double platinum plug. Bosch 8106 is a direct-fit style spark plug for many GM vehicles, including Buick Century, Chevrolet Impala, Chevrolet Malibu, Pontiac Grand Am, and Pontiac Grand Prix applications listed in the fitment data.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Can Address

• Hard starting caused by worn spark plug electrodes
• Rough idle from inconsistent spark delivery
• Misfire conditions related to plug wear or gap erosion
• Reduced ignition efficiency in high-mileage service
• Service intervals shortened by standard copper plug wear

Installation Notes and Tips

• Do not gap this spark plug; the gap is preset from the factory.
• Verify the vehicle calls for a double platinum, tapered-seat plug before installation.
• Check the existing plug specification against thread diameter, reach, heat range, and seat type.
• Use the vehicle service manual for torque and removal procedures.
• Inspect ignition components if misfire symptoms remain after replacement.

Quality Assurance

Bosch builds this OE Fine Wire Double Platinum plug to meet original equipment specifications for double platinum spark plugs. The platinum-on-platinum electrode design is used to reduce gap erosion and support long-term performance in the listed GM and Cadillac applications.
