This billet aluminium clamp is designed specifically for the 123IGNITION distributor used in Porsche 356 and 912 models. It replaces the original 2mm thick clamp and the spacer ring, ensuring that the distributor is mounted correctly within the 3-piece engine housing. The clamp's design guarantees optimal pressure, preventing the distributor from resting too low on the drive shaft, which can cause operational issues.

With a clamping surface of 9mm, significantly larger than the original 2mm, this clamp ensures a secure fit that prevents slipping into the groove. By replacing the spacer ring supplied with the Porsche 123IGNITION distributor, this clamp provides a more reliable and stable installation, enhancing the overall performance and longevity of your classic Porsche engine.
