Spark plugs (PACK OF 6), Double-iridium. Porsche 997 Turbo and GT2 ❭ 99917010390
- Porsche 997 MK1 TURBO 2007-09
- Porsche 997 MK1 GT2 2007-09
- Porsche 997 MKII GT2 RS 2011-13
OE Match double-iridium spark plug set (pack of 6) designed as a direct replacement for Porsche factory spark plugs. Supplied as a complete set of six, it is specifically intended for the high-performance engines found in the Porsche 997 Turbo and 997 GT2.
PACK OF 6
Fits:
Porsche 997 Turbo 3.6L 2007 - 2009 (M97.70)
Porsche 997 GT2 2007 - 2009 (M97.70)
Porsche 997.2 GT2 RS 2011 - 2013
This OE Match double-iridium spark plug set contains 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 on Porsche 997 Turbo and GT2 models.
Each spark plug generates a precisely timed electrical spark to ignite the air-fuel mixture in its cylinder. As a complete set, they ensure uniform combustion across all six cylinders, supporting smooth engine operation and reliable turbocharged performance.
Function:
• Provides reliable ignition for all six cylinders
• Double-iridium electrodes improve spark stability and service life
• Supports smooth idle and responsive acceleration
• Helps maintain power delivery and fuel efficiency under boost
Spark plugs in high-performance 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/uneven idle
• Loss of throttle response or power under boost
• Increased fuel consumption
• At manufacturer-recommended service intervals
• During routine ignition system servicing

Spark plugs play a critical role in Porsche engines, which operate with high compression ratios and tight tolerances.
Correct spark plug performance is essential for modern Porsche engines, which rely on accurate ignition timing and efficient combustion. This NGK spark plug ensures smooth engine operation, stable idle, responsive throttle input, and optimal fuel burn. It is an ideal replacement during routine servicing, diagnostics, or when replacing individual worn plugs.
The plug installs directly with no modification required and is suitable for both everyday driving and higher engine loads.
Function:
• Produces a consistent ignition spark for efficient combustion
• Supports smooth idle, responsive acceleration, and stable power delivery
• Maintains fuel efficiency and emission control
Worn or incorrect spark plugs can cause misfires, rough idle, reduced power, increased fuel consumption, and higher emissions. Replacing spark plugs with a quality NGK component ensures ignition performance remains consistent with Porsche factory expectations while protecting engine efficiency and long-term reliability.
When to replace:
• Engine misfires or uneven idle
• Reduced throttle response or hesitation
• Increased fuel consumption
• At Porsche-recommended service intervals
• During routine ignition servicing or tune-ups
