Information
Spark plug, FR6 NPP, Double-iridium
OE Match double-iridium spark plug features iridium on both the centre and ground electrodes, delivering a finer, more durable ignition point that resists wear and provides a consistently strong spark. The double-iridium design improves spark stability and longevity compared to conventional plugs, making it ideal for modern performance-oriented engines.
Sold individually, 6 or 8 spark plugs required per engine.
Fits:
Porsche 997 Turbo / Turbo S 3.8L 2010 - 2013 [6 Required]
Porsche 997 GT2 RS 2011 - 2013 [6 Required]
Porsche 991 Turbo / Turbo S 3.8L 2014 -2020 [6 Required]
Porsche 957 (MKII) Cayenne Turbo / Turbo S 4.8L 2008-10 [8 Required]
Porsche 958 (MKIII) Cayenne Turbo / Turbo S 4.8L 2011 - 2018 [8 Required]
Porsche 970 Panamera Turbo 4.8L V8 2010 - 2016 [8 Required]
Manufactured to OE-equivalent specifications, this spark plug is built to withstand high combustion temperatures, increased cylinder pressures, and sustained operation under boost. It helps support smooth idle quality, sharp throttle response, efficient combustion, and consistent power delivery across the rev range - all essential for turbocharged engines. This OE Match plug installs directly with no modification required and is ideal for routine servicing, tune-ups, or replacing worn plugs while preserving OE-equivalent performance characteristics.
The spark plug creates a precisely timed electrical spark to ignite the air-fuel mixture in the combustion chamber. The iridium construction ensures a stable, strong spark that promotes efficient combustion, improved throttle response, and smoother engine operation.
Function:
• Generates reliable ignition for efficient combustion
• 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 are subject to high heat and combustion stress, especially in turbocharged engines. Over time, plugs can wear, leading to misfires, rough running, reduced power, and poor efficiency. Replacing worn plugs with an OE Match double-iridium spark plug helps maintain optimal ignition performance, prolongs service intervals, and protects ignition coils and catalytic converters from damage caused by incomplete combustion.
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
