Bosch Silver Spark Plug FR8DS Overview
The Bosch Silver FR8DS spark plug is built for older European performance engines and select motorcycle applications that run at higher combustion chamber temperatures. Its silver-alloy center electrode tip helps resist wear and maintain consistent ignition performance in demanding service.
For Volkswagen owners searching for a Bosch Silver spark plug FR8DS for a Cabrio, Jetta, Golf, or Passat, this plug is a direct secondary ignition service part with a preset gap and resistor design.
Key Features
- Silver center electrode tip for improved wear resistance in high-temperature operation
- Resistor spark plug design for reduced electrical interference
- Preset .7 mm gap; do not gap before installation
- Standard ground electrode configuration with one ground electrode
- 14 mm thread diameter, 19 mm reach, and 16 mm hex size
- Flat seat, non-projected ceramic insulator, 4-cycle spark plug type
- Manufacturer heat range 8 for specified European applications
Detailed Description
Bosch Silver FR8DS is engineered around a silver-alloy center electrode tip, nickel-chromium ground electrode tip material, and nickel-y yttrium plus copper core construction to handle the thermal demands found in older European performance engines. The preset gap and resistor configuration support stable ignition output without additional adjustment. This Bosch Silver line is aimed at applications where electrode wear is a concern and consistent spark delivery matters over time.
Compatible With 1995-2002 Volkswagen Cabrio, N/A; 1993-1999 Volkswagen Jetta, N/A; 1993-1998 Volkswagen Golf, N/A; and 1995-1996 Volkswagen Passat, N/A. The FR8DS part number is also useful when cross-checking Bosch Silver spark plug FR8DS listings for these Volkswagen applications.
What It Helps Address
- Misfire caused by worn or heat-stressed spark plug electrodes
- Hard starting related to weak or inconsistent spark output
- Rough idle from degraded secondary ignition performance
- Loss of throttle response tied to aging spark plugs
- Ignition interference concerns in resistor-equipped systems
Installation Notes and Tips
Install the plug at the preset gap and do not re-gap it. Verify the vehicle calls for a flat-seat, 14 mm thread, 19 mm reach spark plug with the specified heat range before installation. Use the FR8DS part number to confirm the correct application for Volkswagen Cabrio, Jetta, Golf, or Passat models listed above.
Quality Assurance
Bosch designs the Silver line for higher-temperature European engine applications where electrode durability is important. The FR8DS follows Bosch’s specified construction and fitment details for the listed vehicles, including Volkswagen Cabrio, Jetta, Golf, and Passat applications.
