123ignition

Distributor Cap 6-Cylinder.

The 123ignition 6-Cylinder Distributor Cap is a replacement ignition component designed for compatible 123ignition electronic distributors  123SWSML6R and 123SWSML6RV  
Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

The distributor cap forms the high-voltage connection between the ignition coil, distributor rotor and individual spark plug leads. As the rotor turns inside the cap, ignition voltage is directed to each cylinder in the correct firing sequence, allowing the spark plugs to ignite the air-fuel mixture.

Even though a 123ignition distributor uses electronic ignition control, the distributor cap and rotor remain service items because they continue to carry and distribute high ignition voltage. Over time, electrical arcing, heat, moisture and deposits can wear the internal contacts and insulation.
What This Product Does:

• Distributes high-voltage ignition current to the four spark plugs.
• Works with the distributor rotor to send the spark to each cylinder in the correct firing order.
• Provides connection points for the ignition coil and HT leads.
• Electrically insulates the high-voltage terminals from one another.
• Helps maintain a strong, consistent spark at each cylinder.
• Supports reliable starting and smooth engine operation.
• Helps prevent unwanted electrical arcing between terminals.
• Replaces a cracked, worn, contaminated or electrically damaged distributor cap.

The rotor passes close to each internal terminal as it rotates, allowing ignition voltage to jump the small air gap and travel through the corresponding HT lead to the spark plug.
Symptoms Of Wear Or Failure:

• Common signs of distributor-cap deterioration include:
• Difficult or intermittent starting.
• Engine misfires.
• Rough or unstable idle.
• Hesitation during acceleration.
• Loss of power under load.
• Poor throttle response.
• Intermittent running problems.
• Engine cutting out or refusing to start.
• Misfires that become worse in damp or wet conditions.
• Visible cracks in the distributor cap.
• Carbon tracking inside the cap.
• Burnt or eroded internal terminals.
• Corrosion or oxidation on the contacts.
• Moisture or condensation inside the cap.
• Evidence of electrical arcing.
• Excessive deposits around the terminals.
• Damaged or loose HT lead connections.

Carbon tracking often appears as thin dark lines across the inside surface of the cap. These conductive paths can allow ignition voltage to travel to the wrong terminal or to earth rather than reaching the intended spark plug.
Why Replacement Matters:
The distributor cap handles thousands of volts every time the engine fires. Each internal terminal is repeatedly exposed to electrical arcing as the rotor distributes ignition voltage between cylinders.

Over time, this can erode the terminals and reduce the cap's ability to transfer voltage efficiently. Heat, vibration and ageing can also cause the cap material to crack, while moisture and contamination can provide alternative paths for the ignition current.

A deteriorated cap can result in:

• Weak or inconsistent spark.
• Engine misfires.
• Poor starting.
• Reduced performance.
• Increased fuel consumption.
• Rough running.
• Unburnt fuel entering the exhaust.
• Increased stress on other ignition components.

Replacing a worn distributor cap restores a clean and correctly insulated path for ignition voltage, helping the ignition system deliver consistent spark energy to each cylinder.
