00-012 Genuine Bosch Blue Ignition Coil - 12V with Internal Resistor

Bosch 12V Blue Ignition Coil – 00-012

The Bosch 00-012 is a "plug-and-play" solution for classic Volkswagens originally equipped with or converted to 12-volt systems. Its primary advantage is its internal resistance, which prevents the coil from drawing too much current—a common cause of failure for electronic ignition modules like Pertronix. By maintaining a steady 3.4-ohm primary resistance, it provides a hotter, more reliable spark than standard generic coils.

Product Highlights & Features

• Genuine Bosch Quality: Built to the highest standards, outperforming silver or black aftermarket "no-name" coils.

• Universal 12V Compatibility: Works with any 12-volt carbureted engine requiring an internally resisted coil.

• Vibration Resistant: The epoxy filling secures the internal windings, making it ideal for the high-vibration environment of an air-cooled engine.

Technical Specifications

• Part Number: 00-012 (Reference: 043-905-115C)

• Primary Resistance: 3.4 Ohms

• Secondary Resistance: 7.8k Ohms

• Mounting: Zinc-plated bracket included

• Voltage: 12-Volt

Installation & Maintenance Tips

• Verify Polarity: Ensure the power lead (Terminal 15) and the distributor lead (Terminal 1) are connected correctly to avoid a weak spark or module damage.

• Terminal Contact: Clean your wire eyelets before installation to ensure a solid electrical connection, which prevents intermittent misfires.

• Mounting Orientation: Because this coil is epoxy-filled, you can mount it horizontally on the fan shroud or vertically on the firewall with no loss in performance.
