Information
Spark plug, FR6 DPP332 / Z185
The Porsche Genuine OE Spark Plug is an original equipment ignition component designed and manufactured to Porsche’s exact factory specifications for high-performance engines. This OE spark plug (commonly referenced as FR6 DPP 332) delivers reliable, consistent ignition performance exactly as fitted in production.
Sold individually, 6 spark plugs required per engine.
Fits:
Porsche 997 Turbo 3.6L 2007 - 2009 (M97.70)
Porsche 997 GT2 2007 - 2009 (M97.70)
Porsche 997.2 GT2 RS 2011 - 2013
Spark plugs play a vital role in engine combustion by igniting the air-fuel mixture within each cylinder. The OE spark plug produces a stable, timed spark that enables efficient combustion, helping to maximise engine power output, maintain smooth running, and support proper emissions control. Using Porsche-specified plugs ensures that ignition characteristics such as heat range and gap are matched precisely to OEM requirements.
Functions & Technical Role:
• Ignition source: Delivers the spark needed for combustion in each cylinder
• Optimised combustion: Helps the engine run smoothly across idle, part-throttle, and full-load conditions
• OEM heat range & gap: Designed for factory combustion tuning
• Maintains performance: Reduces misfires and supports efficient fuel use
• Durable construction: Genuine components built to last in high-RPM applications
Over time, spark plugs wear due to electrode erosion and combustion by-product deposits. This wear can lead to misfires, rough idle, throttle hesitation, and reduced fuel economy. Replacing aged plugs restores precise ignition timing and combustion quality - preserving engine efficiency, performance, and reliability at design-intent levels.
When to replace spark plugs:
• At manufacturer-recommended service intervals
• During routine engine tune-ups
• If experiencing misfires or unstable idle
• When hard starting occurs
• If fuel economy drops
• During engine rebuilds or diagnostics
