This part is used in the distributor ignition system on selected classic Porsche 911 models.

What This Part Does / Functions
•  Opens and closes the ignition primary circuit inside the distributor
•  Helps trigger the ignition coil to produce spark
•  Supports correct ignition timing and engine running
•  Works with the distributor cam, condenser and ignition coil
•  Helps maintain smooth idle and throttle response when correctly adjusted
•  Replaces worn, burnt, pitted or incorrectly adjusted ignition points
•  Provides correct OE Porsche fitment for the distributor application
•  Supports reliable mechanical ignition system operation.

Why Replace This Part?
Ignition points are normal service items on classic distributor ignition systems. Over time, the contact faces can burn, pit, oxidise or wear, and the rubbing block can wear down, changing the point gap and dwell angle. Worn points can cause poor starting, misfires, weak spark, rough idle, hesitation and incorrect ignition timing. Replacing the point set with a Genuine Porsche OE contact breaker point helps restore correct distributor function and supports reliable ignition performance on classic Porsche 911 engines.

Common Symptoms of Worn Ignition Points
•   Hard starting
•   Rough or unstable idle
•   Misfiring under load
•   Weak or inconsistent spark
•   Poor throttle response
•   Engine hesitation
•   Incorrect dwell angle or point gap
•   Burnt, pitted or contaminated point contacts.

When to Replace This Part
•   During scheduled ignition service
•   If the points are burnt, pitted, oxidised or worn
•   If the rubbing block is worn
•   If the point gap or dwell cannot be set correctly
•   During distributor service or restoration
•   When replacing the condenser, rotor arm or distributor cap
•   If ignition timing becomes unstable
•   When recommissioning a classic 911 with unknown ignition service history

Where It Fits on the Car
This point set fits inside the ignition distributor. It is actuated by the distributor cam and works with the condenser and ignition coil to control spark generation. Correct point gap, dwell angle and ignition timing must be set after installation according to Porsche workshop procedures.
