Sold individually, 6 Required per engine.
Fits:
Porsche 911 3.2L Carrera 1984 - 1989
* Non Catalyst.
Spark plugs are responsible for igniting the air-fuel mixture inside the combustion chamber. Correct specification is essential on non-catalyst engines to ensure stable combustion, strong throttle response, and efficient engine operation. A worn or incorrect spark plug can cause misfires, rough idle, reduced power, and increased fuel consumption.
• Creates a controlled spark to ignite the air-fuel mixture
• Supports smooth engine running and stable combustion
• Helps maintain power delivery and fuel efficiency
Key Functions & Benefits:
• Genuine NGK manufacture
• Supplied as one spark plug (order quantity as required)
• Correct specification for non-catalyst 3.2 Carrera
• OEM-quality materials and construction
• Reliable ignition performance and long service life
Spark plugs are critical to proper combustion, directly affecting engine performance, fuel efficiency, and reliability. Worn or incorrect spark plugs can cause misfires, rough running, poor throttle response, and increased fuel consumption. Regular replacement helps maintain smooth operation and protects key engine components from unnecessary stress.
When spark plugs should be replaced:
• During scheduled servicing intervals
• If the engine shows signs of misfiring or rough idle
• When experiencing poor cold starting
• If fuel consumption increases unexpectedly
• After long-term storage or inactivity
• When plugs show visible wear, fouling, or corrosion

What This Product Does
The ignition coil transforms the vehicle electrical system's low voltage into a high-voltage pulse. This allows the spark plug to ignite the compressed air and fuel mixture at the correct point in the combustion cycle.
Functions
- Generates the high voltage needed by the spark plug
- Supports consistent ignition within its assigned cylinder
- Helps maintain smooth starting, idling and acceleration
- Forms part of the engine's direct-ignition system
Technical Details
- Genuine Porsche ignition coil
- Porsche part number: 9A160210408
- Supplied individually
- Six ignition coils are required per six-cylinder engine
- Supersedes Porsche references 9A160210401, 9A160210402 and 9A160210403
Symptoms of Fault
- Intermittent or persistent engine misfiresRough idle or hesitation during acceleration
- Difficult starting, particularly when the engine is hot
- Reduced engine power or limp modeI
- lluminated engine warning light
- Misfire or ignition-coil circuit fault codes
- Poor fuel economy caused by incomplete combustion.
Why Replacement Matters
Heat, vibration and electrical stress can gradually weaken the internal insulation of an ignition coil. Replacing a confirmed faulty unit helps restore dependable spark delivery and reduces the risk of continued misfiring. Check the spark plug, connector, wiring and engine earths during diagnosis, as faults in these areas can produce similar symptoms or place additional strain on the coil.

FAQs
Can an ignition coil fail only when hot?Yes. Heat can expose deterioration within the insulation or electrical connections, causing an intermittent misfire after the engine warms up.
Should a coil be replaced using only a fault code?
A fault code identifies the affected circuit or cylinder but should be supported by checks of the spark plug, connector, wiring, supply voltage and earth connection.
Should the spark plugs also be inspected?
Yes. Worn, damaged or incorrectly specified spark plugs can increase the electrical load placed on an ignition coil.
