Product Information

Rotor Arm.
The OE Match Rotor Arm is a high-quality ignition system component designed to distribute high-voltage electrical current from the distributor cap to the correct spark plug lead in the engine's firing sequence. Manufactured to OE specifications for fit, electrical performance and durability, this rotor arm is a critical part of the distributor-based ignition system found on many classic Porsche models.

Fits:

Porsche 944S 2.5L 16V 1987-88
Porsche 944S2 3.0L 16V 1989-91
Porsche 968 3.0L 1992-94
Porsche 968 Sport 3.0L 1994-95
Porsche 968 CS 3.0L 1993-95
Porsche 968 Turbo S 3.0L 1993-94

Constructed from high-grade insulating materials with a precision-engineered conductive contact, the rotor arm rotates within the distributor and accurately transfers ignition voltage to each cylinder at precisely timed intervals. Designed to withstand high temperatures, electrical loads and engine operating conditions, it helps ensure reliable engine starting, smooth running and efficient combustion.

What This Product Does:

Transfers ignition voltage from the distributor cap to the spark plug leads.
Distributes spark to each cylinder in the correct firing order.
Supports reliable engine starting and operation.
Ensures accurate ignition timing within the distributor system.
Promotes efficient fuel combustion.
Helps maintain smooth engine performance.
Supports optimum fuel economy and emissions control.
Forms an essential component of the ignition system.

Symptoms Of Wear Or Failure:

Engine misfires.
Rough idling or poor engine performance.
Difficulty starting the engine.
Intermittent ignition faults.
Hesitation during acceleration.
Reduced fuel efficiency.
Loss of engine power.
Engine stalling.
Visible burning, pitting or corrosion on the contact surface.
Cracks or damage to the rotor arm body.

Why Replacement Matters:

Rotor arms are exposed to continuous high-voltage electrical currents, heat and mechanical rotation whenever the engine is running. Over time, the conductive contact can wear, corrode or burn, while the insulating body may develop cracks or deterioration that affect ignition performance.
A worn rotor arm can cause inconsistent spark delivery, resulting in misfires, poor drivability, reduced performance and increased fuel consumption. If left unresolved, ignition faults can place additional strain on spark plugs, ignition leads and other ignition system components.
Replacing a worn rotor arm restores reliable spark distribution and helps maintain smooth, efficient engine operation. An OE Match replacement provides factory-style fitment, dependable electrical performance and long-lasting durability, ensuring the ignition system continues to perform as intended while preserving the reliability and driving enjoyment expected from your Porsche.

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.
