Perma-Tune Gen 6

Replace those tired and worn ignition components with this Ignition Kit

Contents of Kit
3 Pin CDI Module - Premium Version
Distributor with Harness
Ignition Coil

The Gen 6 Premium Perma-Tune CDI module makes diagnostics easier by providing onboard diagnostics that are automatically displayed by two coloured LED function lights.
These LED lights assist in diagnosing both the ignition module and the car. The green LED is a status indicator that can flash diagnostic fault codes. The red LED is a strobe light that flashes each time the coils fires in the same manner as a timing light which is especially useful for detecting engine misfire.
The LED function lights are mounted in the harness electrical connector and can only be seen with a mirror while the module is powered up.
As an additional feature of the Perma-Tune Premium module, there are three self-resetting overload protectors that protect your Perma-Tune and your car from overload damage. The overload protectors are hidden underneath the ignition module so they do not spoil the original look of the part.

Distributor with Harness
Distributors wear out and rob your engine of the horsepower it was intended to produce. Worse yet, they can leave you stranded or even damage the crankshaft ring gear. Forget about rebuilding an outdated distributor with hard to find parts when you can replace it with modern technology that looks original. Replacing that worn out distributor has never been easier with the Perma-Tune Bespoke distributor, for the 2.0 L and 2.2 L engine. There are no wires to cut and splice: the distributor has the electrical harness built in and features the original equipment compatible connectors for a plug and play installation.
Simply mount the ignition module to the relay panel where the later model cars had the module mounted and then plug the distributor harness connector into the Perma-Tune module. The power, ground, tachometer and coil connections are made at the existing coil wires. The harness has loop connections that allow joining the wires without having to cut and splice the car harness wires. The Perma-Tune distributor harness is made using the same vinyl sleeve loom construction as the original wiring for that factory original look.
The Perma-Tune Bespoke Porsche distributor is an exact fit replacement part that will drop right into the engine. Setting the static timing is easy with the built in trigger point LED that lets you know when the rotor is pointing in the right direction. Idle timing is set in exactly the same way as the factory manual indicates and the factory mechanical and vacuum curves are preprogrammed into the distributor. The mechanical vacuum can is replaced with a reliable MAP sensor that is fully programmable to perform advance or retard vacuum functions. It just doesn't get any easier than this.

Ignition Coil
The Perma-Tune Black Ignition Coil is specifically designed to operate with all Perma-Tune modules to maximize the performance and service life of your Perma-Tune ignition module. It has the period correct look for the Porsche 911SC with a brown top and black body and will fit the original mounting bracket and wiring harness of the car.
The Black ignition coil is very rugged and can resist the heat and vibration that it will encounter on a vintage car engine. Triple seals insure that the dielectric oil inside the coil will not leak out. The high Voltage tower is extra thick to resist arcing and will still fit the original spark plug wire boot. The internal components of the coil are designed to resist deterioration to provide a long life.

Distributor with Harness
Ignition Coil

CDI Module
The Gen 6 Perma-Tune for the 911SC comes in two models: Premium ignition module and the Basic ignition module. The Basic model is just that, basic: it performs only the same functions as the analog modules did back in the day. For the average street car, this may be all that is desired and of course is more affordable than the Premium model. It is however still a high performance part and is perfect for racing venues that do not allow programmable digital ignition systems. The Basic model has a smooth, more original looking housing than the Gen 5 cast housing.

Distributor
Replacing that worn out distributor has never been easier with the Perma-Tune Bespoke distributor for the 911SC 3.0L engine and other engines like the Porsche Turbo 930 that use the six pin ignition module. There are no wires to cut and splice: the distributor has the electrical harness built in and features the original equipment compatible connectors for a plug and play installation. Simply unplug the car harness connector from the ignition module and plug it into the matching connector of the distributor harness. Then plug the distributor harness connector into the Perma-Tune module and done. There is no way to make a mistake with this installation, the connectors will only plug in the right way. The harness connector has built in diagnostics lights that tell you when the ignition system has power and when the ignition module is making sparks. The blue connector LED is a power indicator and the red connector LED is a strobe light that flashes each time the ignition system makes a spark, just like a timing light.

This module comes preprogrammed for the Porsche 911SC so programming changes are optional. The Gen 6 Premium Perma-Tune makes diagnostics easier by providing onboard diagnostics that are automatically displayed by two coloured LED function lights. These LED lights assist in diagnosing both the vehicle and the ignition module. The green LED is a status indicator that can flash diagnostic fault codes. The red LED is a strobe light that flashes each time the coils fires in the same manner as a timing light. This LED is especially useful for detecting intermittent engine misfire caused by wiring or distributor problems. The LED function lights are mounted in the harness electrical connector and can only be seen when the module is powered up. There are three self-resetting overload protectors that assist in troubleshooting while protecting your Perma-Tune from damage. The overload protectors are hidden underneath the ignition module so they do not spoil the original look of the part.

911 Bosch Direct Fit COP Ignition Coils - High-Performance Ignition Upgrade for Porsche 911 G-Model (1975–1989)
6x coilpacks for your 911 coil on plug conversion

The Adapt Motorsports Bosch Direct Fit COP Ignition Coils offer a modern ignition upgrade for Porsche 911 G-Model (1975–89) engines undergoing EFI and aftermarket ECU conversions. These proven, high-performance Bosch coils provide a strong, consistent spark and mount directly into the original plug holes for a secure, high-integrity installation.

Fits:

  • Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
  • Porsche 911 1978-1983 3.0L / SC
  • Porsche 911 1984-1986 3.2L
  • Porsche 911 1987-1989 3.2L G50
  • Porsche 911 1975-1977 3.0L Turbo (930)
  • Porsche 911 1978-1989 3.3L Turbo (930)


These coils require spark plugs with a smaller ceramic to fit correctly. Plugs such as IW22 iridiums work well.

Designed specifically for aftermarket fuel injection and engine management systems, these coils are not compatible with the original DME controller. They require an upgraded ECU and wiring loom, making them an essential component in performance builds, restomods or distributor-delete conversions. Adapt Motorsports provides pinout information and ECU setup guidance, while installation is typically integrated into a broader EFI upgrade project.

When removing the original ignition components, these coils work in conjunction with the Adapt Motorsports Ignition Sync Module—installed in the former distributor location—to provide accurate engine position sensing for precise ECU control.

These coils fit securely in the original plug holes. For use as lower coils in twin-plug applications, we recommend adding a retention tab from the lower rocker cover bolt and a heat shield to safeguard the coil from exhaust heat.  

These ignition coils deliver tested reliability, strong spark energy, and proven Bosch performance, making them ideal for enhancing throttle response, tuning accuracy, and ignition efficiency on modified Porsche 911 engines.

What Do COP Ignition Coils Do?
Coil-On-Plug (COP) ignition coils provide a dedicated ignition source at each spark plug, delivering improved spark strength and timing precision compared with older single-coil and distributor systems.

Core Functions:

  • Deliver high-energy spark directly at the plug for cleaner combustion.
  • Improve ignition timing accuracy with standalone ECU control.
  • Support performance tuning, higher RPM stability and EFI upgrades.
  • Eliminate the need for ignition leads and distributor-based systems.
  • Enhance throttle response, efficiency, and engine smoothness.

These coils modernise classic Porsche 911 engines for performance and reliability aligned with contemporary ignition technology.

Why Do Traditional Porsche Ignition Components Fail?

Original-style ignition systems in 911 G-Models include ageing components prone to deterioration after decades of use.

Common Causes of Failure Include:

  • Heat stress weakening ignition coils and internal windings.
  • Distributor wear, including worn bearings and mechanical advance issues.
  • Cracked caps or degraded ignition leads causing inconsistent spark delivery.
  • Oil contamination or moisture ingress.
  • Spark scatter at high RPM due to mechanical limitations.

When ignition strength deteriorates, drivability, tuning accuracy and engine performance are noticeably compromised.

Why Replace or Upgrade to Adapt Motorsports Direct Fit COP Coils?

Upgrading to a COP conversion offers significant improvements in consistency, efficiency, and performance—particularly in EFI-equipped engines.

Key Benefits:

  • High-energy, reliable spark delivery for enhanced combustion.
  • Compatible specifically with aftermarket EFI and standalone
  • ECUs. Direct-fit Bosch coils proven for durability and performance.
  • Secure installation into original spark plug holes.
  • Ideal for distributor-delete conversions and modern ignition control.

About Ignition Coil

Ignition Coils – Reliable Spark and Power Delivery for Porsche Engines

Ignition coils are essential components in your Porsche’s ignition system, transforming low-voltage power from the battery into the high-voltage energy required to ignite the air-fuel mixture inside the engine cylinders. A healthy ignition coil ensures smooth acceleration, efficient combustion, and consistent engine performance.

At Design911, we supply a wide range of genuine and high-quality ignition coils for various Porsche models including 356, 911, 924, 944 and 928. Each coil is precision-engineered for durability, heat resistance, and optimal spark performance, ensuring your Porsche continues to deliver the power, efficiency, and reliability it was designed for.

What Do Ignition Coils Do?

Ignition coils play a crucial role in your Porsche’s ignition system by converting 12-volt battery power into up to 40,000 volts to fire the spark plugs. Their main functions include:

  • Generating high-voltage spark energy for combustion.
  • Delivering consistent ignition timing across all cylinders.

Modern Porsche models may feature coil-on-plug systems that provide precise, individual spark control for each cylinder — maximising performance and responsiveness.

Why Do Ignition Coils Fail?

Over time, ignition coils are subjected to high voltage, heat, and vibration, which can cause wear or internal damage. Common causes of failure include:

  • Heat degradation of coil insulation or wiring.
  • Moisture intrusion leading to short circuits.
  • Age-related electrical fatigue in coil windings.
  • Faulty spark plugs causing excessive resistance and strain.
  • Corrosion or poor electrical connections.

Typical symptoms include engine misfires, rough idling, loss of power, difficulty starting, or an illuminated check engine light.

Why Replace Faulty Ignition Coils?

A failing ignition coil can cause poor fuel economy, misfires, or damage to the catalytic converter. Replacing worn or damaged coils restores proper spark strength, combustion efficiency, and overall engine performance.

Benefits of replacement include:

  • Smoother acceleration and stronger performance.
  • Reduced misfires and improved fuel economy.
  • Lower emissions and smoother idle.
  • Long-lasting, manufacturer-quality reliability.

All ignition coils in our range are made using high-grade materials and advanced insulation technology, ensuring consistent voltage delivery, heat resistance, and dependable performance under demanding conditions.

1. What does an ignition coil do in a Porsche?
The ignition coil converts the car’s 12-volt battery power into a high-voltage spark that ignites the fuel-air mixture in each cylinder. This ensures smooth engine operation, efficient combustion, and reliable performance.

2. What are the symptoms of a bad ignition coil?
Common signs of a failing ignition coil include engine misfires, rough idling, reduced acceleration, poor fuel economy, and a check engine light. You may also notice hesitation or vibration when accelerating.

3. Can I drive my Porsche with a bad ignition coil?
Driving with a failing ignition coil is not recommended. It can cause engine misfires, loss of power, and long-term damage to spark plugs or the catalytic converter. Replacement should be done promptly to avoid costly repairs.

4. How long do ignition coils last on a Porsche?
Typically, ignition coils last between 60,000 and 100,000 miles, depending on driving conditions and maintenance. Regular spark plug replacement and avoiding moisture exposure can extend their lifespan.

5. Are manufacturer-quality ignition coils as good as genuine Porsche parts?
Yes — manufacturer-quality ignition coils are built to the same precise specifications and performance standards as genuine parts. They provide excellent fitment, voltage output, and long-term reliability, often at a more cost-effective price.
