Information
Spark plug FGR 6 KQE
This OE Match spark plug set includes 6 replacement ignition plugs for Porsche flat-six engine applications. The set is designed to match the original-style fitment and function, making it suitable for routine service, misfire repair, or preventative engine maintenance.
SET OF 6
Fits:
Porsche Boxster 986 2.7L 1999-02
Porsche Boxster S 986 3.2L 1999-02
Porsche Boxster 986 2.7L 2003-04
Porsche Boxster S 986 3.2L 2003-04
Porsche 996 C2 3.4L 1997-08/01
Porsche 996 C4 3.4L 1997-08/01
The spark plugs ignite the air and fuel mixture inside each combustion chamber. Correctly operating spark plugs help support smooth starting, stable idle, clean combustion, throttle response, fuel efficiency, and reliable engine performance.
Functions
• Replaces all 6 spark plugs
• FGR 6 KQE spark plug specification
• Provides ignition spark for each cylinder
• Supports smooth starting and stable idle
• Helps maintain clean combustion and throttle response
• Suitable for routine ignition service or misfire diagnosis
• OE Match replacement set for Porsche flat-six engine maintenance.
Why Replace This Set?
Spark plugs wear over time due to heat, combustion pressure, electrode erosion, carbon build-up, and mileage. Worn spark plugs can cause misfires, rough idle, hesitation, poor starting, reduced performance, increased fuel consumption, or engine warning lights. Replacing all 6 spark plugs together helps restore consistent ignition across the engine.
When to Replace This Set
• Spark plug service interval is due
• Engine misfire, rough idle, or hesitation is present
• Starting performance is poor
• Fuel economy has reduced
• Acceleration feels uneven or weak
• Engine warning light or ignition fault codes are present
• Preventative maintenance is being carried out.
Where it fits on the car
These spark plugs fit in the engine cylinder head ignition system. One spark plug is fitted per cylinder.

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.

The spark plug generates a precisely timed electrical spark to ignite the air-fuel mixture inside the combustion chamber. The platinum-iridium construction ensures stable ignition, efficient combustion, and long-term performance consistency.
Function:
• Produces a reliable ignition spark for efficient combustion
• Platinum-iridium electrodes improve durability and spark consistency
• Supports smooth idle and responsive throttle behaviour
• Helps maintain fuel efficiency and controlled emissions
Spark plugs in air-cooled engines are exposed to high operating temperatures and sustained combustion stress. Worn or incorrect plugs can cause misfires, rough running, reduced performance, and poor fuel efficiency. Replacing worn plugs with an OE Match platinum-iridium spark plug restores stable ignition, balanced combustion, and helps preserve engine longevity and performance.
When to replace:
• Engine misfires or uneven idle
• Hesitation or reduced throttle response
• Increased fuel consumption
• At manufacturer-recommended service intervals
• During routine engine servicing or tune-ups
