12 Plug Distributor with Anti-Clockwise Rotation - Bosch Style
Bring modern ignition control to your classic air-cooled
Porsche with this advanced 12 Plug Distributor with Anti-Clockwise Rotation,
manufactured in the historic style of the legendary Bosch 3.0 RSR ignition
distributor. Combining authentic period-correct appearance with
state-of-the-art electronic technology, this distributor is the ultimate
ignition upgrade for high-performance Porsche 911 Turbo and twin-plug engine
applications.

- Porsche 911 1978-1989 3.3L Turbo (930)
Designed for enthusiasts seeking improved drivability, performance, engine protection and tuning flexibility, this distributor delivers fully programmable ignition control via Bluetooth smartphone connectivity while retaining the iconic appearance of a classic Bosch motorsport distributor.
Specifically configured as a left-rotating distributor and designed for use with two 3-pin CDI (Capacitive Discharge Ignition) units, this system is ideally suited to twin-plug Porsche engines requiring precise ignition control under both naturally aspirated and turbocharged operating conditions.
What Does the Distributor Do?
The distributor is responsible for accurately delivering ignition signals to the spark plugs at precisely the correct moment throughout the engine's operating range.
In a twin-plug Porsche engine, the distributor controls:
- Spark timing
- Ignition advance curves
- Cylinder firing sequence
- Twin-plug ignition operation
- Engine starting performance
- Engine efficiency
- Throttle response
- Combustion quality
Accurate ignition timing is essential for extracting maximum performance while maintaining reliability and engine safety.
Why Upgrade to a Programmable Distributor?
Traditional mechanical distributors rely on fixed advance mechanisms that offer limited adjustment and tuning flexibility.
This modern programmable distributor provides:
- Fully programmable ignition maps
- Smartphone Bluetooth connectivity
- Boost-sensitive ignition control
- Vacuum advance functionality
- Rev limiter programming
- Integrated immobiliser system
- Improved engine protection
- Greater tuning precision
The result is significantly greater control over engine performance across all operating conditions.
Historic Bosch RSR Appearance
Inspired by the original Bosch 3.0 RSR ignition distributor, this unit preserves the appearance of Porsche's most iconic motorsport ignition systems.
Benefits include:
- Period-correct appearance Motorsport-inspired design
- Authentic engine bay presentation
- Ideal for restorations and restomods
- Combines classic looks with modern technology
Perfect for enthusiasts seeking modern functionality without sacrificing originality.
Bluetooth Smartphone Programming
The integrated Bluetooth system allows ignition maps and distributor functions to be adjusted directly from a smartphone application.
Features include:
- Wireless ignition mapping
- Real-time adjustments
- User-friendly interface
- Quick tuning changes
- No specialist programming equipment required
- Simplified engine setup
This enables precise ignition optimisation for a wide range of engine specifications and operating conditions.
Integrated Pressure Sensor Technology
One of the distributor's most advanced features is the integrated manifold pressure sensor.
A vacuum or boost reference hose can be connected directly from the intake manifold to the distributor.
This allows:
- Vacuum advance functionality
- Boost retard functionality
- Load-sensitive ignition timing
- Improved part-throttle efficiency
- Enhanced turbocharged engine safety
- Optimised combustion characteristics
The system can overlay manifold pressure corrections onto the RPM-based ignition map for highly accurate ignition control.
Integrated Rev Limiter and Immobiliser
The distributor includes advanced engine protection and security features.
Rev Limiter
Benefits include:
- Protects against over-revving
- Safeguards expensive engine components
- Adjustable RPM settings
- Improved reliability
Immobiliser with PIN Protection
Benefits include:
- Enhanced vehicle security
- Smartphone programmable access
- Additional theft protection
- Discreet integrated functionality

A design fault on engines up to August 1993 that you MUST fix if not already done so is to add ventilation to the distributor to prevent ozone perishing the distributor drive belt. If this breaks you will be running on one plug per cylinder and will end up with poor performance and possible damage.
The solutions is to also fit a Venting kit.

HOW TO FIT: Firstly prise of the oval plate arrowed on the distributor with a screwdriver. Then remove the large black air guide pipe as we need to drill a hole in it at the green dot. The pipe removes by loosening jubilee clips at top and bottom. You will also need to remove two sensor connectors on the pipe. I also removed the two sensors near the distributor so that I had easy access to the plate. Drill at 18mm hole in the pipe, 40mm to the right of the tail light ventilation nipple. Deburr the hole and remove all shavings. Install the rubber grommet (B) into the hole and install the white connector (C) into the grommet.Install the distributor connector (A) into the hole in the distributor where the plate was. Finally refit the air pipe and connect back up all the sensors. Install the hose (D) onto the new distributor and air pipe nipples and route
