This iridium spark plug ignites the compressed air-fuel mixture inside the combustion chamber, enabling controlled combustion and efficient power delivery. The fine iridium electrode produces a strong, focused spark, helping turbocharged engines achieve smoother running, improved throttle response, and reliable ignition under higher cylinder pressures.
Functions & Technical Role:
• High-energy ignition spark for efficient combustion
• Iridium electrode technology for exceptional wear resistance
• Improved ignition stability under turbocharged operating conditions
• Enhanced cold starting performance
• Reduced misfires and uneven running
• Factory-matched heat range & gap for Porsche turbo engines
• Longer service intervals compared to conventional spark plugs
Spark plugs are critical to combustion efficiency, especially in turbocharged engines where cylinder pressures are higher. Over time, electrode wear and carbon build-up reduce spark quality, leading to misfires, poor boost response, and reduced performance. Replacing worn plugs restores reliable ignition, protects engine components, and helps maintain smooth, consistent power delivery.
When to replace spark plugs:
• At Porsche-recommended service intervals
• During routine servicing or ignition system checks
• If experiencing misfires, hesitation, or rough idle
• When cold starting becomes more difficult
• If boost response or performance drops
• During engine rebuilds or restorations
• After long-term vehicle storage before returning to use

Information
Spark Plug, IZKR7B
The Bosch spark plug (0 242 135 510 / IZKR7B) is an OEM-quality replacement designed specifically for the Porsche 955 Cayenne 3.2L V6 with engine code D9J. Manufactured as a direct replacement for Porsche part number 95517021990, this spark plug delivers reliable ignition performance, efficient combustion, and long-lasting durability.
Sold individually, 6 required per engine
Fits:
Porsche 955 Cayenne 3.2L V6 (2003–2006) – Engine Code: D9J
Spark plugs are a critical part of the ignition system, producing the spark that ignites the air-fuel mixture within each cylinder. Correct ignition timing and a strong, consistent spark are essential for smooth engine operation, optimum fuel economy, responsive acceleration, and reduced exhaust emissions. As spark plugs wear, ignition efficiency gradually declines, which can lead to rough idling, reduced performance, increased fuel consumption, and engine misfires.
Key Features & Benefits
• Genuine Bosch OEM-quality spark plug
• Direct replacement for Porsche 95517021990
• Bosch part number 0 242 135 510 (IZKR7B)
• Optimised heat range for the Porsche 3.2L V6 engine
• Supports efficient combustion and fuel economy
• Helps reduce misfires and improve throttle response
• OEM-quality fit, performance, and durability
Why Replacing Spark Plugs Matters
Spark plugs naturally wear over time, reducing the strength and consistency of the ignition spark. Replacing them at the recommended service interval helps restore engine performance, improve fuel efficiency, reduce emissions, and ensure reliable starting in all driving conditions.
When to Replace Spark Plugs
• At the manufacturer's recommended service interval
• If the engine misfires or idles roughly
• Poor fuel economy
• Difficult starting or hesitation under acceleration
• Reduced engine performance
• During a scheduled ignition system service
