Bosch 6V Silver Ignition Coil | Air-Cooled VW & Porsche 356 | 1.5 Ohm Epoxy-Filled w/ Bracket (00-9408-B)

Bosch 6-Volt Silver Ignition Coil | 1.5 Ohm, Epoxy-Filled with Bracket

Bosch 6-volt silver ignition coil, 1.5 ohm primary resistance, epoxy-filled, supplied with a factory-style mounting bracket. The correct coil for original 6-volt air-cooled VWs and other vintage European vehicles still running their factory 6V electrical systems. Part #00-9408-B.

VW Beetles were 6-volt from 1949 through the 1966 model year before switching to 12-volt for 1967. Running a 12V coil on a 6V system produces weak spark and unreliable starting, while a 6V coil on a 12V system burns out the coil and points quickly — match the coil voltage to the vehicle's electrical system.

Vehicle Fitment

• VW Beetle: 1949–1966 (factory 6V)
• VW Bus / Transporter: 1950–1966 (factory 6V)
• VW Karmann Ghia: 1956–1966 (factory 6V)
• VW Type 3: 1962–1966 (factory 6V)
• Vintage European: Porsche 356, BMW, Mercedes and others running 6V points ignition
• Will NOT work for: 12-volt electrical systems (use a 12V coil). 1967 and later VWs were 12V from the factory.

Frequently Asked Questions

• Is my car 6V or 12V? 1966 and earlier VWs were 6V from the factory; 1967 and later were 12V. Many early cars have been converted — check the battery and generator (6V generators are physically smaller than 12V alternators).
• Why epoxy-filled instead of oil-filled? Epoxy-filled coils can be mounted in any orientation because there's no liquid to migrate. This Bosch Silver replaces both epoxy and oil-filled styles and is the more flexible choice.
• Will this work with Pertronix or electronic ignition? Pertronix makes 6V versions of some Ignitor modules — check your unit's specs. A 1.5 ohm coil is generally compatible with most 6V electronic ignition modules.
• Is the bracket the original factory style? Yes — the included bracket matches the factory Bosch coil mounting pattern used on air-cooled VWs.
• Should I convert to 12V instead? That's a separate decision. 12V conversion gives brighter headlights and easier starting but requires replacing the generator, regulator, coil, lights, and any 6V accessories. For a numbers-correct restoration, keep it 6V.
