This distributor is made in the historical design of the original Magneti Marelli ignition distributor and combines the latest technology with an authentic look.
It was installed at the factory on the 906, 911R, 914/6 GT and 911 ST and the ignition map is easily and freely programmable via an app and Bluetooth.
In addition, an immobilizer can be locked/unlocked with a PIN and a speed limiter can also be set easily via a smartphone.
This version requires two 3-pin HKZ devices but it fits all engines from 1965 to 1971, so from the 2.0ltr to the 2.2ltr

Distributor Mounting Clamp for 123Ignition Distributor
Securely install a 123Ignition distributor into a Porsche
356 or 912 3-piece engine case with this upgraded OE Match Aluminium
Distributor Mounting Clamp.
Fits:
- Porsche 912 SWB 1965-1968 (F)
- Porsche 356 1950-55
- Porsche 356A 1955-59
- Porsche 356B 1959-63
- Porsche 356C 1963-65
Specifically designed for use with a 123Ignition distributor, this mounting clamp replaces the original thin 2mm distributor clamp and separate spacer ring arrangement. Its wider 9mm clamping surface provides improved support and more even pressure distribution around the distributor.
The design also helps ensure that the distributor sits at the correct height and rests properly against the engine housing, preventing it from being installed too deeply and incorrectly loading against the distributor drive shaft.
What Does the Distributor Mounting Clamp Do?
The distributor mounting clamp secures the distributor in its correct position within the engine case.
Once the ignition timing has been set, the clamp holds the distributor securely so it cannot rotate or move during engine operation.
When installing a 123Ignition distributor into a classic Porsche 356 or 912 engine, correct positioning is particularly important. The distributor needs to sit at the correct depth within the housing while engaging correctly with the distributor drive.
This upgraded clamp helps:
- Secure the 123Ignition distributor correctly
- Maintain the correct distributor installation height
- Distribute clamping pressure more evenly
- Prevent unwanted distributor movement
- Support accurate ignition timing
- Prevent the distributor from being mounted too deeply
- Provide a more secure mounting arrangement than the original thin clamp
Why Is This Clamp Recommended for 123Ignition Distributors?
The original Porsche distributor clamp has a clamping surface of only approximately 2mm.
When used with a 123Ignition distributor, this narrow clamping surface can create installation problems. In particular, the original clamp can potentially move into the distributor groove rather than providing the intended support.
This upgraded aluminium version increases the clamping surface to 9mm.
The wider contact area provides better pressure distribution and helps ensure that the distributor rests correctly against the engine housing rather than sitting too low and standing on the drive shaft.
9mm Clamping Surface
One of the main improvements is the substantially wider
clamping area.
Original-style clamp: approximately 2mm
Upgraded mounting clamp: 9mm
The increased width provides a more stable contact surface and prevents the clamp from slipping into the distributor groove.
This creates a more positive and secure installation for the 123Ignition distributor.
Correct Distributor Installation Height
A distributor should not be supported by the drive shaft itself.
If a 123Ignition distributor is fitted too deeply into the engine case, it can stand on the distributor drive shaft rather than correctly resting against the engine housing.
This mounting clamp is designed to help establish the correct position, ensuring the distributor is properly supported by the housing while maintaining correct engagement with the drive mechanism.
Alternative to a Spacer Ring
When installing a 123Ignition distributor into a Porsche 356 or 912 3-piece engine case, the use of either a suitable spacer ring or this dedicated mounting clamp is recommended.
This upgraded clamp provides an integrated solution, replacing the original thin clamp and spacer ring arrangement with a single purpose-designed aluminium component.
Porsche 356 / 912 123Ignition Distributor Mounts & Electronic Ignition Upgrades
Upgrading a Porsche 356 or 912 to a 123Ignition electronic distributor is a popular way of introducing modern ignition control while retaining the basic distributor-based layout of the original engine.
Correct installation is essential. The distributor must engage correctly with the drive while sitting at the intended height against the engine housing.
The original thin distributor clamp was designed around the original distributor arrangement and is not necessarily the ideal solution when installing a modern 123Ignition unit.
This purpose-designed aluminium mounting clamp provides a 9mm clamping surface, improving support and pressure distribution while helping maintain the correct distributor position.
It is therefore a worthwhile addition when installing a 123Ignition distributor into a Porsche 356 or 912 3-piece engine case.

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.
