Distributor
By OE Match
- 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.
- Control interface: smartphone app using Bluetooth.
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.

OEMatch Distributor — Fit, Function, Confidence
Distributors route high-voltage current from the ignition coil to each spark plug in the correct firing order and timing. For Porsche models, OEMatch Distributor items are chosen to suit classic and later ignition systems, helping to restore reliable spark delivery, smooth idle and consistent throttle response.
Available Types
- Complete distributor assemblies
- Distributor caps
- Rotor arms
- Rebuild kits
Understanding OEMatch Distributor
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original distributor. OE (Original Equipment) refers to parts matching original specifications for the distributor and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM distributor engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. The distributor controls spark timing and distribution, delivering current from the coil to each plug in the correct sequence. In older Porsche engines the unit can include mechanical and vacuum advance mechanisms that adjust timing with engine speed and load; wear or electrical faulting in these parts affects combustion and drivability.
Benefits Include
- Restored ignition timing accuracy
- Improved fuel efficiency and throttle response
- Elimination of misfires and hard starting
Why Distributor Wear and Fail
- Worn bearings or shafts causing misalignment
- Cracked distributor caps allowing moisture or dirt intrusion
- Faulty rotor arms or carbon tracking leading to weak or inconsistent spark
- Corrosion on electrical contacts or inside the cap
The Importance of Replacing with OEMatch Distributor
A worn or damaged distributor can cause poor performance, misfires and starting issues. Replacing faulty components helps restore smooth engine operation, consistent combustion and dependable starting. OEMatch provides a wide selection for Porsche applications and has catalogued over 4,000 individual part numbers with more than 8,700 OE cross-references to aid identification and fitment for many model years.
Advantages
- Complete assemblies for straightforward replacement
- Rebuild kits to refurbish existing units where appropriate
- Caps and rotors matched to ignition system specifications
Support & Advice
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified.
