Bosch Black High-Energy Ignition Coil | Air-Cooled VW & Vintage European | 12V 3.4 Ohm (00-9575-0)

Bosch Black High-Energy Ignition Coil — 12V, 3.4 Ohm

Genuine Bosch 12-volt black high-energy ignition coil with 3.4 ohm primary resistance. Designed for stock points ignition or compatible electronic ignition modules on 12V air-cooled VWs and other vintage European vehicles. Part #00-9575-0 (Bosch OE cross-reference 9244771008).

Vehicle Fitment

• 12-volt VW Beetle, Karmann Ghia, Type 3, Bus, and Thing: With stock points ignition
• Air-cooled VWs converted from 6V to 12V: Compatible
• Vintage Porsche, BMW, Mercedes and other 12V points-ignition vehicles: Using a 3.0–3.5 ohm coil

Will NOT work for: 6-volt electrical systems (use a 6V coil instead). Confirm electronic ignition compatibility before pairing with low-resistance-required modules like MSD or Pertronix Ignitor III.

Why Choose the Bosch Black Coil?

The Bosch Black is the modern high-energy version of the classic Bosch automotive coil line. It produces a stronger, more consistent spark than older oil-filled coils, particularly at higher RPM and under load, while remaining fully compatible with stock VW points ignition. The 3.4 ohm primary resistance is in the same range as factory-spec coils, so it works with stock points and most electronic ignition modules without requiring a ballast resistor.

Key Features & Benefits

• High-Energy Spark: Sealed high-energy design delivers a hotter, more consistent spark than oil-filled coils.
• Points & Module Friendly: 3.4 ohm primary works with stock points and most electronic modules, no ballast resistor required.
• Any-Orientation Mounting: Sealed construction removes the upright-only requirement of oil-filled coils.
• Genuine Bosch: German OE-supplier quality.

Frequently Asked Questions

• Black vs Blue Bosch coil — what's the difference? The Bosch Blue is a long-standing oil-filled coil; the Bosch Black is a sealed high-energy design with slightly hotter spark output. Both are 12V and roughly the same resistance range. For a numbers-correct restoration, the Blue is more period-correct. For a daily-driven car where slightly hotter spark is a plus, the Black is the better choice.
• Will this work with Pertronix Ignitor? Yes, with the standard Ignitor (Ignitor I). For Ignitor II and III, check Pertronix's coil resistance requirements — those modules typically want a lower-resistance coil.
• Can I mount it in any orientation? Yes. Sealed high-energy coils don't have the upright-only requirement that oil-filled coils have.
• Is the bracket included? Listings vary — confirm at order. The Black coil typically uses a standard VW coil bracket if you're replacing an existing Bosch coil.
• What's the OEM cross-reference? Bosch 9244771008. Useful when sourcing or cross-checking against vintage parts manuals.
