Information
Spark plug, FR6 DPP332 / Z185, Double-iridium
High-quality OE Match double-iridium spark plug engineered to replicate the original Porsche factory spark plug in fit, heat range, and performance. Specifically designed for the demanding combustion environment of the Porsche 997 Turbo and 997 GT2, this plug delivers reliable ignition and long-lasting durability under high thermal and mechanical load.
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
This OE Match double-iridium spark plug features iridium-tipped electrodes on both the centre and ground sides, providing a finer, more durable firing point compared to standard plugs. The double-iridium design enhances spark efficiency, improves wear resistance, and supports stable combustion even under the elevated temperatures and pressures typical of turbocharged engines.
Manufactured to OE-equivalent standards, this spark plug offers precise thread dimensions, optimal electrode geometry, and a specific heat range calibrated for performance engines. It helps maintain smooth idle quality, crisp throttle response, efficient fuel burn, and consistent power delivery - all critical for the high-output Porsche 997 Turbo and GT2 platforms.
Designed as a direct replacement, this spark plug installs without modification and is ideal for routine service, tune-ups, or replacing worn plugs to preserve peak engine performance.
The spark plug delivers a precisely timed electrical spark that ignites the air-fuel mixture in the combustion chamber. The double-iridium construction supports a stable, strong spark and helps maintain efficient combustion over extended use.
Function:
• Generates reliable ignition for efficient combustion
• Double-iridium electrodes improve spark stability and electrode life
• Supports smooth idle and responsive acceleration
• Helps maintain power delivery and fuel efficiency under boost
Spark plugs degrade over time due to repeated heat cycles, high pressures, and electrical load. On performance engines like the 997 Turbo and GT2, worn or incorrect plugs can lead to misfires, hesitation, reduced power, and uneven combustion. Installing an OE Match double-iridium spark plug ensures dependable ignition performance, extended service life, and preserved driving characteristics aligned with Porsche engineering.
When to replace:
• Engine misfires or rough idle
• Loss of throttle response or power under boost
• Increased fuel consumption
• At manufacturer-recommended service intervals
• During routine ignition servicing or tune-ups
