A correctly functioning distributor cap is essential for reliable engine starting, smooth idling, consistent acceleration and dependable ignition performance.

The cap is fitted to the ignition distributor and contains the electrical contacts responsible for distributing ignition voltage to the spark plug leads.

What This Part Does / Functions
  • Distributes high-voltage ignition pulses to the spark plug leads.
  • Directs ignition voltage to the correct cylinder in firing order.
  • Works with the distributor rotor arm and ignition coil.
  • Provides insulated connections for the HT leads.
  • Supports consistent spark delivery and combustion.
  • Helps maintain smooth engine starting, idling and acceleration.
  • Replaces a cracked, worn or electrically damaged distributor cap.
  • Maintains the correct factory Porsche ignition configuration.

Why Replace This Part?
Distributor caps are exposed to engine heat, vibration, moisture and repeated high-voltage electrical discharge.

Over time, the internal contacts can become worn, corroded or eroded, while the cap housing may develop cracks or carbon tracking. These issues can interfere with ignition voltage distribution and cause misfires, hesitation, rough running or starting difficulties.

Replacing a worn cap with a Genuine Porsche distributor cap helps restore reliable ignition performance.

When to Replace
  • This Part During ignition system servicing.
  • If the distributor cap is cracked or damaged.
  • When internal terminals show excessive wear or corrosion.
  • If carbon tracking is present.
  • When replacing the distributor rotor arm or ignition leads.
  • During engine tune-up or restoration
  • If ignition faults are traced to the distributor cap.
  • When restoring the ignition system with Genuine Porsche components.

Where It Fits on the Car
The distributor cap is fitted to the engine ignition distributor, within the rear engine compartment. It sits over the distributor rotor and provides the connection points for the ignition coil and spark plug HT leads.

Correct lead positioning is essential to maintain the engine's firing order.
