12 Volt Ignition Coil, 3.4 Ohm

The Bosch 12-Volt Black Coil is a genuine, oil-filled ignition component designed as an industry standard for air-cooled Volkswagen enthusiasts seeking reliable, high-energy spark. With a primary resistance of 3.4 Ohms, it acts as a bridge between vintage reliability and modern performance needs. Its oil-filled construction within a standard canister size aids in heat dissipation, preventing the common issue of heat-soak that can degrade performance in lesser-quality coils. It is compatible with standard points-and-condenser ignition systems, where its resistance helps protect points from premature burning, and is also powerful enough to drive 4- and 6-cylinder electronic ignition modules, such as the Pertronix Ignitor series. Officially listed as OE Part Number 9 244 771 008, this coil is specifically designed for a wide range of 12-volt Volkswagen applications, including Type 1 (Beetle, Ghia) from 1967-1979, Super Beetle (1971-1979), Type 2 (Bus, Transporter) from 1967-1979, Type 3 (Fastback, Squareback, Notchback) from 1967-1973, Type 181 'The Thing' (1973-1974), and Karmann Ghia (1967-1974). It is also ideal for custom applications like sandrails, dune buggies, and trikes utilizing VW-based engines, and for those performing 6-volt to 12-volt conversions. Key specifications include 3.4 Ohms primary resistance, 7.4 Ohms secondary resistance, 12-volt compatibility only, and oil-filled internal construction for maximum heat dissipation. The standard canister dimensions ensure a direct fit for most applications.
