Spark plug, FR5 NPP
The Porsche Genuine OE Spark Plug 99917023590 is the factory-specified ignition plug for petrol-powered Macan, Cayenne, and Panamera models with 3.0L and 3.6L V6 engines from approximately 2014 to 2018. It delivers the reliable spark, combustion quality, and durability expected from OE Porsche components, maintaining smooth engine performance and efficient burn throughout the lifespan of the engine.
Sold individually, 6 spark plugs required per engine.

Fits:
Porsche 95B.1 Macan S 3.0L / Turbo 3.6L 2014 - 2018
Porsche 958 Cayenne 3.6L V6 Turbo / V6 Turbo GTS 2015 - 2018
Porsche 970.2 Panamera S 3.0L 2014 - 2016

Designed as a direct replacement for both 99917023590 and the earlier 99917023390, this spark plug installs without modification and is ideal for routine servicing, scheduled maintenance, or replacement of worn ignition components.

Spark plugs play a vital role in the engine’s ignition system by producing the electrical spark that ignites the air-fuel mixture in each cylinder. Proper ignition ensures smooth engine starting, efficient combustion, and stable performance across idle and load conditions. This OE spark plug ensures the correct heat range, electrode design, and spark characteristics Porsche engineers specified for optimal combustion performance.

• Routine engine servicing and ignition tune-ups
• Replacing worn or fouled spark plugs to restore smooth performance
• Ignition system refresh during diagnostic work
• Routine maintenance to support fuel economy and emissions performance
• OEM part fit for restorations or warranty-compliant repairs

Spark plugs gradually wear due to heat, carbon build-up, and electrode erosion. As they age, the spark can weaken and combustion becomes less efficient, leading to rough idle, hesitation, poorer fuel economy, and increased emissions. Replacing plugs with Genuine Porsche OE spark plugs ensures correct gap, heat range, and ignition performance - preserving engine smoothness and power delivery to factory levels.

When to replace:
•  At manufacturer-recommended service intervals
•  During routine ignition system servicing
•  If experiencing misfires, rough idle, or hesitation
•  When engine starting becomes inconsistent
•  If fuel economy drops or emissions increase
•  During engine diagnostics or rebuild work

Keep your Porsche running at peak performance with our complete Ignition Coils Service Kit.
Price is Each (6pcs Required per engine).
For optimal engine efficiency, Porsche recommends replacing ignition coils at regular intervals - every 30,000 miles for the Macan and every 40,000 miles for the Cayenne and Panamera. When ignition coils begin to fail, you may notice a check engine light triggered by a cylinder misfire. This can lead to reduced performance, rough running, poor fuel efficiency, and in severe cases, engine damage.

What Does an Ignition Coil Do? 
An ignition coil is a crucial part of your vehicle’s ignition system. It converts the battery’s low voltage into the high-voltage current needed to create a spark at the spark plug — igniting the air-fuel mixture inside each cylinder.

When an ignition coil starts to fail, you may experience:
• Engine misfires: Jerking or shuddering during acceleration due to incomplete combustion.
• Rough idling: Noticeable vibration or shaking when the vehicle is at rest.
• Reduced engine power: Sluggish acceleration or loss of performance.
• Illuminated check engine light: Often indicating a misfire code. Hard starting or backfiring: Caused by inconsistent or weak sparks.
