This OE Match double-iridium spark plug set includes six identical spark plugs, each manufactured to OE-equivalent standards for thread dimensions, electrode geometry, and thermal characteristics. Featuring iridium on both the centre and ground electrodes, these plugs provide a finer, more stable spark and significantly improved resistance to wear compared to conventional spark plugs.
Turbocharged Porsche engines operate under extreme heat and pressure, making ignition quality critical. This OE Match set supports stable combustion, smooth idle, sharp throttle response, and efficient fuel burn under boost. Replacing all six spark plugs together ensures balanced ignition across cylinders and consistent power delivery throughout the rev range.
Designed as direct replacements, these spark plugs install without modification and are ideal for routine servicing, tune-ups, or ignition system maintenance.
Function:
• Provides reliable ignition for all six cylinders
• Double-iridium electrodes enhance spark stability and durability
• Supports smooth idle and responsive acceleration
• Helps maintain power delivery, fuel efficiency, and emissions control
Spark plugs in turbocharged engines are exposed to extreme temperatures and pressures. Worn or degraded plugs can lead to misfires, hesitation under boost, reduced power, and increased fuel consumption. Replacing all six plugs with an OE Match double-iridium set restores reliable ignition, balanced combustion, and helps protect ignition coils and engine components.
When to replace:
• Engine misfires or rough idle
• Hesitation under acceleration
• Reduced throttle response or power delivery
• Increased fuel consumption
• At manufacturer-recommended service intervals
• During routine engine tune-ups or ignition servicing

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
