Bosch OE Fine Wire Double Platinum Spark Plug 8104
Bosch 8104 is an OE Fine Wire Double Platinum spark plug built for direct-replacement service in a wide range of GM applications. It uses platinum on the center electrode and platinum in the ground electrode to reduce gap erosion and maintain stable ignition performance over time.
Key Features
- Double platinum design for improved durability and longer service life
- Fine-wire center electrode helps maintain consistent spark delivery
- Resistor plug with 6000 ohms resistance
- Projected ceramic insulator for OE-style combustion chamber placement
- 14 mm thread diameter, 17.5 mm reach, tapered seat
- Preset gap; do not gap before installation
- Heat range 8 with standard ground configuration
Product Line Details
Bosch OE Fine Wire Double Platinum plugs are built to match original equipment requirements for double platinum applications. The design combines a platinum firing pin with a platinum inlay on the ground electrode to help control wear at the gap and support consistent operation in vehicles that call for this plug style.
Detailed Description
This Bosch spark plug is a direct-fit ignition component for many Chevrolet, GMC, Cadillac, Buick, Pontiac, Hummer, Saab, Isuzu, and Geo applications. It is commonly used in vehicles such as the Chevrolet Silverado 1500, Chevrolet Tahoe, GMC Sierra 1500, Cadillac Escalade, and Chevrolet Camaro where OE-style double platinum construction is specified. Bosch 8104 is also listed for long-running truck and van platforms including the Chevrolet Express 2500, GMC Savana 3500, and Silverado HD models. The preset gap and OE-style electrode materials support stable ignition performance without additional adjustment.
Common Issues It Can Address
- Rough idle caused by worn spark plug electrodes
- Hard starting from weakened ignition output
- Misfire conditions related to plug wear or gap erosion
- Reduced throttle response from inconsistent spark delivery
- Service intervals shortened by standard-plug electrode wear
Installation Notes and Tips
- Install only in applications that specify Bosch 8104 or an OE Fine Wire Double Platinum plug.
- Do not gap the plug; the gap is preset from the factory.
- Verify thread diameter, reach, seat type, and heat range before installation.
- Use proper torque procedures for tapered-seat spark plugs to avoid thread or sealing damage.
- Replace plugs on the engine schedule recommended for the vehicle platform.
Quality Assurance
Bosch engineers this plug to meet original equipment specifications for double platinum spark plug applications. The platinum center and ground electrode materials are selected to reduce gap erosion and support long service life in OE-style ignition systems.
