Distributor cap. Porsche 924 1976-80 / Porsche 912E ❭ 113905207C
- Porsche 924 2.0L 1976-79
- Porsche 924 2.0L 1980-85
- Porsche 912E 4CYL 1976
This cap forms the upper section of the distributor assembly, routing high-voltage current from the ignition coil to each spark plug wire in the correct firing order.
Fits:
Porsche 924 1976 - 1980
Porsche 912E
Over time, original caps can crack, carbon-track, corrode at the terminals, or develop moisture ingress - all of which reduce ignition performance. Installing a fresh cap restores clean, strong spark delivery and stable engine operation.
A deteriorated or damaged distributor cap can cause:
• Misfires, hesitation, or rough running
• Hard starting, especially in damp weather
• Weak or inconsistent spark delivery
• Poor fuel efficiency or lack of power
Replacing the cap is a simple, effective way to restore ignition reliability and smooth engine performance.

The distributor cap is the critical link in the ignition system that routes high-voltage energy from the ignition coil, via the rotor, to each spark plug in the proper sequence. A properly functioning cap ensures consistent spark delivery, accurate ignition timing, smooth combustion and efficient engine operation - all essential for reliable engine performance and drivability.
Over time, distributor caps can suffer from heat, vibration, moisture and electrical stress. This may lead to cracks, carbon tracking, corrosion on contacts or degraded insulation - all of which can cause misfires, rough idle, ignition instability or failure to start. Installing the correct distributor cap restores clean, dependable spark delivery, improves reliability and helps avoid ignition-related issues.
When to replaces:
• Visible cracks, wear or carbon tracking on the cap surface or contacts
• Intermittent misfires, rough idling or poor engine performance
• Difficulty starting, especially in damp conditions
• Original cap is decades old or suspected to be brittle
• Conducting a full ignition system refresh (rotor, points, cap, wires)
• After exposure to dampness, oil, or contaminants - ensuring the ignition system is sealed and protected
