Product Information
Spark Plugs, FGR 5KQEO.
Replacing spark plugs as a complete set is essential for balanced combustion and even engine performance. This OE Match pack of six is the correct solution for scheduled maintenance, tune-ups, or resolving misfire and rough-running issues caused by worn or aged plugs. It installs directly with no modification required.
PACK OF 6

Fits:
Porsche 996 Carrera 3.6L 2001 - 2005
Porsche 987 Boxster 2.7L / 3.2L 2005 - 2008
Porsche 987C Cayman 2.7L / 3.2L 2005 - 2008
Porsche 997 Carrera 3.6L / 3.8L 2005 - 2008

Supplied as a complete set of six, it is ideal for full engine servicing on compatible Porsche six-cylinder engines.

Each spark plug delivers a precise electrical spark to ignite the air-fuel mixture in its respective cylinder. As a complete set, they ensure uniform combustion across the engine, supporting smooth running and consistent performance.

Function:
  Provides reliable ignition for all six cylinders
  Supports smooth idle, acceleration, and throttle response
  Helps maintain fuel efficiency and engine balance
  Designed to match OE Porsche heat range and performance
  Supplied as a complete engine set for correct servicing

Spark plugs wear over time due to heat and combustion stress. Replacing all six plugs together ensures even ignition timing across cylinders, prevents misfires, restores lost performance, and protects catalytic converters from damage caused by incomplete combustion. Using an OE Match set ensures correct performance without compromising reliability.

When to replace:
  Rough idle or misfires
  Poor acceleration or throttle response
  Increased fuel consumption
  After the manufacturer’s recommended interval
  During regular engine tune-up or service
