Information
Distributor Cap
For Marellli S112AX and S112BX distributors.
Produced in original Bakelite and it looks and performs as original.
Fits:
Porsche 911 T/S 1969 - 1971
Porsche 914-6
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

Ignition Tune-Up Kit
An ignition tune-up kit includes all the parts you need to service your vehicle's ignition system. Components like spark plugs, ignition coils, spark plug connectors, and spark plug wires will eventually require replacement.
When these components are used past their useable service life you will often experience a vehicle that does not run smoothly, suffers from misfires, or even completely dead cylinders due to no spark. Replacing ignition components should be done on a regular interval
Ignition Tune-Up Kit Failure Symptoms
- Check engine light due to misfire
- P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308 and other cylinder specific misfire OBD fault codes
- Hesitation while accelerating
- Poor fuel economy due to incomplete combustion
