Information
BOSCH Distributor cap
High-quality Bosch distributor cap for selected Porsche 911 Carrera 3.2L and Porsche 964 Turbo models. The Bosch 1235522368 distributor cap cross-references Porsche OE number 93060291900 / 93060291903 and is designed as a direct replacement for the original ignition distributor cap.
Fits:
Porsche 911 3.2L 1984 - 1989
Porsche 965 1991 - 1994
The distributor cap is a key component of the ignition system, routing high-voltage current from the ignition coil through the distributor rotor and onwards to each spark plug in the correct firing sequence.
Over time, the internal contacts can become worn, burnt or corroded, while the cap body can develop cracks or carbon tracking. These issues can lead to weak or inconsistent spark delivery, particularly under load.
Replacing a worn distributor cap with the correct Bosch component helps restore reliable ignition performance and smooth engine operation.

What Does the Distributor Cap Do?
The distributor cap forms part of the engine's ignition system.
High voltage produced by the ignition coil is supplied to the centre of the distributor cap. The rotating distributor rotor then directs this voltage to each terminal within the cap in the correct firing order.
The electrical current then travels through the ignition leads to the spark plugs.
Correct distributor-cap operation is important for:
- Reliable engine starting
- Stable idle
- Consistent spark delivery
- Smooth acceleration
- Correct combustion
- Reliable performance at higher engine speeds
Signs of a Worn Distributor Cap
A distributor cap is exposed to continuous electrical arcing, engine-bay heat, vibration and age.
Common signs of wear can include:
- Difficult starting
- Engine misfires
- Rough or uneven idle
- Hesitation under acceleration
- Loss of engine performance
- Intermittent ignition faults
- Moisture-related starting problems
- Burnt or corroded internal contacts
- Carbon tracking
- Cracks in the distributor cap housing
Even when the cap appears acceptable externally, wear to the internal contacts can reduce ignition performance.
Bosch Ignition Components
Bosch has a long history of supplying ignition components for Porsche vehicles.
Using the correct Bosch distributor cap helps retain the intended fit and electrical characteristics of the original ignition system while providing a high-quality replacement for a worn component.
