- Porsche 911 1978-1983 3.0L / SC
This OE Match Bosch-style 12-plug ignition distributor, it combines anticlockwise rotation with smartphone-based ignition programming.
Fits
- Porsche 911 SC - 1978 to 1983
What This Product Does
The distributor directs ignition pulses to the spark plugs in firing sequence. Its appearance follows the period Bosch 3.0 RSR design, while Bluetooth connectivity allows the ignition map to be configured through an app.
Smartphone controls also provide an adjustable engine-speed limit and a PIN-operated immobiliser. This version needs two 3-pin HKZ ignition units; confirm that the intended ignition installation matches this requirement before fitting.
Functions
- Distributes ignition pulses across a 12-plug installation.
- Allows ignition-map adjustment through a Bluetooth-connected app.
- Provides smartphone adjustment of the engine-speed limit.
- Enables PIN-controlled immobiliser activation and deactivation.
Technical Details
- Application: Porsche 911 SC, 3.0L, 1978–1983.
- Rotation direction: anticlockwise.
- Configuration: 12-plug distributor.
- Styling reference: Bosch 3.0 RSR.
- Ignition requirement: two 3-pin HKZ units.

Symptoms of Fault
- Uneven idling or intermittent misfiring.
- Difficulty starting or unexpected stalling.
- Hesitation or backfiring during acceleration.
- Unstable timing readings during inspection.
- Excessive movement at the distributor shaft or rotor.
- Internal moisture, corrosion or oil contamination.
These signs are not exclusive to distributor faults. Inspect the plugs, leads, coil, wiring and electrical connections before deciding which component needs attention.
Why Replacement Matters
Wear within a distributor can disturb spark distribution and ignition timing. Renewing a confirmed faulty assembly addresses defects that changing only the cap or rotor may leave unresolved. For an engine rebuild or ignition conversion, check the complete ignition arrangement rather than assuming compatibility from the vehicle model alone.
FAQs
Is this a Bosch-manufactured distributor?
The supplied brand is OE Match; Bosch style describes its period-inspired appearance.
How is the ignition map adjusted?
Programming is carried out through a smartphone app connected by Bluetooth.
Which ignition units does it require?
This configuration requires two 3-pin HKZ units.
Will a new cap and rotor resolve shaft wear?
No. Internal mechanical wear requires separate assessment, even if the service components are renewed.
Check fitment for your specific vehicle (model, year, engine) before ordering.
