What This Product Does
This connector forms the connection between an ignition lead and its spark plug. It is an ignition connection component, rather than the spark plug itself or a complete ignition lead set.
Functions
- Connects the ignition lead to the spark plug terminal.
- Provides the plug-end connection within the ignition circuit.
- Allows renewal of the connector when inspection identifies deterioration.
Technical Details
- Porsche part number: 91160231300.
- Porsche identification: cylinder 3, exhaust-side spark plug connector.
Symptoms of Fault
- Misfiring or an uneven idle.
- Hesitation, particularly under engine load.
- Ignition problems that become more noticeable in damp conditions.
- Cracked insulation, loose connections or corroded terminals.
- Tracking marks indicating electrical leakage.
Why Replacement Matters
A deteriorated connector can interrupt the ignition connection or allow electrical leakage. Replace it when inspection confirms damage, corrosion or poor contact, rather than assuming that a misfire identifies this component alone. Check the associated lead and spark plug during diagnosis, as faults elsewhere in the ignition system can produce similar symptoms.
FAQs
Is this a spark plug or a complete lead set?
No. Part 91160231300 is the spark plug connector.
Should replacement be based only on a misfire?
No. Inspect the connector, lead and plug, and confirm the fault before replacing components.
