Bosch OE Fine Wire Platinum Spark Plug 6708
Bosch 6708 is an OE Fine Wire Platinum spark plug built for steady ignition performance and improved fuel efficiency. It uses a fine-wire platinum center electrode with a tapered ground electrode to support reliable spark delivery in a wide range of GM and Buick applications.
The Bosch OE Fine Wire Platinum line focuses on OE-style fit and function, making it a practical upgrade from conventional copper-core plugs for drivers servicing older Chevrolet, GMC, Buick, Oldsmobile, and Pontiac engines.
Key Features
- Platinum center electrode tip for consistent ignition performance
- Tapered ground electrode design for improved ignitability
- Resistor plug with 6000 ohms resistance
- Preset 1.3 gap; do not gap before installation
- Tapered seat, 14 mm thread diameter, 16 mm hex size
- Ceramic insulator with non-projected tip design
- OE Fine Wire Platinum construction for OE-style replacement service
Detailed Description
Bosch part number 6708 is engineered to meet or exceed Original Equipment specifications for platinum spark plugs. The fine-wire design helps concentrate the spark, while the platinum firing pin on the center electrode and nickel-ytttrium ground electrode materials support stable operation under everyday driving conditions. This spark plug is a direct service choice for many classic and late-1980s through mid-1990s GM platforms, including Chevrolet C1500, GMC K1500, and Buick Regal applications.
For fitment-based searches, Bosch 6708 is a strong match for owners looking for a Bosch spark plug for Chevrolet C1500, GMC Safari, or Pontiac Grand Prix service. It is also listed for many Chevrolet and GMC truck, van, and SUV engines where the preset gap and OE-style platinum design are specified.
What It Helps Address
- Hard starting caused by worn or inconsistent spark plugs
- Rough idle from degraded ignition performance
- Misfire concerns related to aged secondary ignition components
- Reduced fuel economy from inefficient spark delivery
- Maintenance intervals where an OE-style platinum plug is specified
Installation Notes and Tips
- Do not gap the plug; the gap is preset from the factory.
- Verify the tapered seat, 14 mm thread diameter, and 16 mm hex before installation.
- Confirm vehicle-specific fitment by year, make, and model before service.
- Use the correct torque procedure for the cylinder head material and plug seat type.
- Inspect ignition wires, coils, and boots during spark plug replacement to avoid repeat misfire issues.
Quality Assurance
Bosch OE Fine Wire Platinum plugs are built to OE-style specifications for platinum spark plug applications and are intended for direct replacement service in listed vehicles. Part number 6708 is designed around factory-style dimensions and ignition requirements for the confirmed fitment range.
This part fits 1135 vehicles
Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
