Information
Iridium Spark Plug, 14FR 7 LDU
This OE Match iridium spark plug features an iridium-tipped electrode, offering a finer and more consistent spark compared to standard spark plugs. The iridium construction improves ignition efficiency and provides increased resistance to wear, making it well suited to the operating demands of Porsche flat-six engines.
Sold individually, 6 required per engine
Fits:
Porsche 996 Carrera / 4 3.4L 08/1997 - 07/1999 (Engine M96.01)
Porsche Boxster 986 2.5L i 24V 08/1996 - 07/1999 (Engine M96.20)
Porsche Boxster 986 2.7L i 24V 08/1999 - 07/2002 (Engine M96.22)
Porsche Boxster S 986 3.2L i 24V 08/1999 - 07/2002 (Engine M96.21)
Porsche 955 Cayenne S 4.5L 05/2002 - 05/2006 (Engine M48.00)
Manufactured to OE-equivalent standards, this spark plug delivers correct thread dimensions, electrode geometry, and thermal characteristics required for stable combustion. It supports smooth idle, crisp throttle response, efficient fuel burn, and consistent power delivery throughout the rev range.
Designed as a direct replacement, this spark plug installs without modification and is ideal for routine servicing, tune-ups, or replacement of individual worn plugs while maintaining OE-equivalent ignition performance.
The spark plug generates a precisely timed electrical spark inside the combustion chamber to ignite the air-fuel mixture. This ignition process enables efficient combustion, smooth engine operation, and reliable power output.
Function:
• Produces a reliable ignition spark for efficient combustion
• Iridium electrode improves spark stability and durability
• Supports smooth idle and responsive acceleration
• Helps maintain fuel efficiency and controlled emissions
Spark plugs wear due to heat, combustion pressure, and electrical load. Worn plugs can cause misfires, rough idle, reduced performance, and increased fuel consumption. Replacing worn plugs with an OE Match iridium spark plug restores reliable ignition, balanced combustion, and smooth engine performance.
When to replace:
• Engine misfires or uneven idle
• Hesitation or reduced throttle response
• Increased fuel consumption
• At manufacturer-recommended service intervals
• During routine ignition system servicing

Information
Ignition coil pack.
This ignition coil is designed for use in select Porsche engines. Its function is to convert the output voltage of the vehicle's 12V battery into the high-voltage pulse required by each spark plug, ensuring efficient ignition of the fuel-air mixture and smooth engine operation.
Sold each, 6 Required per engine.

• This product supersedes. Porsche's old part numbers: 9A160210401, 9A160210402, 9A160210403, 9A160210404, 9A160210405, 9A160210406
• Position on Vehicle: Mounted on top of the engine, on each ignition-coil tower (direct ignition design); one coil per cylinder.
• Applications: Suitable replacement when original ignition coil shows wear, misfires, or performance issues — restoring reliable spark delivery, smooth running and correct engine behaviour.
The ignition coil is fundamental to your engine’s ignition system: it supplies the high-voltage spark to each cylinder. When a coil fails or degrades, symptoms may include misfires, rough idling, loss of power, increased emissions or even engine warning lights. Replacing a degraded unit with a fresh coil restores reliable ignition, optimal engine performance and helps prevent downstream damage (e.g., catalytic converter issues).
When and why to replace:
• Engine misfires, rough idle, or “choppy” acceleration.
• Trouble codes referencing misfire or coil circuit faults.
• One or more cylinders showing mis-fire despite spark plugs being serviceable.
• During tune-up/maintenance when coils are accessible and nearing service interval.
• Preventive replacement on high-mileage or original equipment coils to avoid sudden failure.
