Information
Spark plug, FR6 DPP332 / Z185, Double-iridium
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

What This Product Does
The ignition coil transforms the vehicle electrical system's low voltage into a high-voltage pulse. This allows the spark plug to ignite the compressed air and fuel mixture at the correct point in the combustion cycle.
Functions
- Generates the high voltage needed by the spark plug
- Supports consistent ignition within its assigned cylinder
- Helps maintain smooth starting, idling and acceleration
- Forms part of the engine's direct-ignition system
Technical Details
- Genuine Porsche ignition coil
- Porsche part number: 9A160210408
- Supplied individually
- Six ignition coils are required per six-cylinder engine
- Supersedes Porsche references 9A160210401, 9A160210402 and 9A160210403
Symptoms of Fault
- Intermittent or persistent engine misfiresRough idle or hesitation during acceleration
- Difficult starting, particularly when the engine is hot
- Reduced engine power or limp modeI
- lluminated engine warning light
- Misfire or ignition-coil circuit fault codes
- Poor fuel economy caused by incomplete combustion.
Why Replacement Matters
Heat, vibration and electrical stress can gradually weaken the internal insulation of an ignition coil. Replacing a confirmed faulty unit helps restore dependable spark delivery and reduces the risk of continued misfiring. Check the spark plug, connector, wiring and engine earths during diagnosis, as faults in these areas can produce similar symptoms or place additional strain on the coil.

FAQs
Can an ignition coil fail only when hot?Yes. Heat can expose deterioration within the insulation or electrical connections, causing an intermittent misfire after the engine warms up.
Should a coil be replaced using only a fault code?
A fault code identifies the affected circuit or cylinder but should be supported by checks of the spark plug, connector, wiring, supply voltage and earth connection.
Should the spark plugs also be inspected?
Yes. Worn, damaged or incorrectly specified spark plugs can increase the electrical load placed on an ignition coil.

Spark plugs are essential components of the ignition system, responsible for generating the electrical spark that ignites the air-fuel mixture within the combustion chamber. Correct specification spark plugs help maintain smooth idle, reliable cold starts, responsive throttle performance, efficient fuel combustion, and controlled emissions. Over time, spark plugs wear or become fouled, which can lead to misfires, reduced engine power, rough running, or increased fuel consumption.
Manufactured by Bosch, a world-renowned original equipment supplier to Porsche, these spark plugs are engineered to OEM specifications with the proper heat range and electrode design required by modern flat-six engines. Durable construction and precise manufacturing help deliver stable ignition performance, long service life, and dependable operation under both daily and spirited driving conditions. Ideal for routine servicing, preventative maintenance, or restoring peak performance.
