Information
Rotor arm
An OE Match rotor arm designed for the ignition distributor, responsible for directing high-voltage current to the correct spark plug in Porsche 911 SC and 930 Turbo models. Installed within the distributor, the rotor arm rotates in sync with the engine, transferring high-voltage current from the ignition coil to each spark plug terminal in the correct firing order.
Fits:
Porsche 911 all Turbos 3.0L / 3.3L and 911 3.0L without KAT 1975-89
The "rotor" head is attached to the top of the distributor shaft which is driven by a gear on the engine's camshaft and thus synchronized to it. This rotor is pressed against a carbon brush on the center terminal of the distributor cap which connects to the ignition coil either through the top and wired directly to the coil in HEI systems, or via the centre terminal in points ignition systems and remotely connected to the coil.
The rotor is constructed such that the centre tab is electrically connected to its outer edge so that voltage coming in to the centre post travels through the carbon point to the outer edge of the rotor. As the camshaft rotates, the rotor spins and its outer edge passes each of the internal plug terminals to fire each spark plug.
