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.

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.
- Suitable
for twin-plug applications with lower-coil retention tab and heat shield
(recommended).
- Requires
spark plugs with smaller ceramic sections—such as Denso IW22 Iridium—for
correct fitment.
These coils are engineered to support modern engine
management strategies, making them essential for high-performance or restomod
Porsche 911 builds.
