Details on Bosch Silver Product Line
The Bosch Silver line focuses on delivering spark plugs with silver-tipped electrodes, which provide improved electrical conductivity compared to standard copper plugs. This results in better ignition efficiency and stable engine performance. The FR8DS spark plug within this line is tailored for 4-cycle engines, making it suitable for Volkswagen vehicles requiring precise ignition components.
Technical Description and Compatibility
The FR8DS spark plug features a 6000 ohm resistor to reduce electromagnetic interference, ensuring smooth operation of onboard electronics. Its flat seat design and 14mm thread diameter with a 19mm reach make it compatible with Volkswagen models such as the Cabrio, Golf, Jetta, and Passat. The single ground electrode with a standard tip design complements the silver center electrode, which is constructed from nickel-yttrium and copper for durability and efficient heat transfer. The ceramic insulator is non-projected, providing reliable insulation and resistance to fouling.
