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.

Fits:

  • 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

Why Choose This Distributor?

This distributor delivers capabilities traditionally only available through standalone engine management systems.

Benefits include:

  • Historic Bosch appearance
  • Modern programmable technology
  • Bluetooth smartphone control
  • Vacuum advance functionality
  • Turbo boost retard capability
  • Twin-plug compatibility
  • Integrated rev limiter
  • Integrated immobiliser
  • Precise ignition control
  • Porsche-specific design
