Product Information
Spark plug, FR5 NPP,  Double-iridium
OE Match double-iridium spark plug features iridium on both the centre and ground electrodes, providing a finer, more stable spark and significantly improved resistance to wear compared to standard spark plugs. The double-iridium construction supports extended service intervals and consistent ignition performance under demanding operating conditions.
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.

The spark plug generates a precisely timed electrical spark to ignite the air-fuel mixture inside the combustion chamber. The double-iridium design ensures consistent spark quality and reliable combustion over extended mileage.

Function:
 Provides reliable ignition for efficient combustion
 Double-iridium electrodes improve spark stability and durability
 Supports smooth idle and responsive acceleration
 Helps maintain fuel efficiency and controlled emissions

Spark plugs wear due to heat, combustion pressure, and electrical load. Worn or outdated plugs can cause misfires, rough idle, reduced performance, and increased fuel consumption. Replacing them with an OE Match double-iridium spark plug restores reliable ignition, supports efficient combustion, and helps protect ignition coils and exhaust components.

When to replace:
  Engine misfires or uneven idle
  Reduced throttle response or hesitation
  Increased fuel consumption
  At manufacturer-recommended service intervals
  During routine ignition system servicing

Product Information
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

About Spark Plugs

Porsche Spark Plugs | Design911 High-Performance Ignition Components for Power & Efficiency

Spark plugs play a vital role in the performance, efficiency, and reliability of your Porsche’s engine. They ignite the air-fuel mixture inside the combustion chamber, creating the precise explosion needed to generate power. High-quality spark plugs ensure clean ignition, smooth acceleration, and reduced emissions — helping your Porsche perform exactly as intended on every drive.

At Design911, we stock a full range of spark plugs from leading manufacturers, engineered for superior conductivity, heat resistance, and long service life. Available in iridium, platinum, and copper-core designs, each spark plug is precision-crafted to match your Porsche’s specific ignition requirements. Ideal for routine maintenance, tuning, or complete engine rebuilds, our spark plugs ensure reliable performance from idle to redline.

What Do Spark Plugs Do?

Spark plugs are critical ignition components that deliver the electric spark required to ignite the air-fuel mixture in the combustion chamber.

Core Functions:
• Create a high-voltage spark to initiate combustion.
• Ensure smooth, efficient engine operation.
• Support optimal fuel economy and throttle response.
• Reduce emissions through clean, consistent ignition.
• Maintain balanced power delivery and idle stability.

When properly maintained, spark plugs enhance both performance and fuel efficiency, ensuring your Porsche runs with precision and reliability.

Why Do Spark Plugs Fail or Degrade?

Spark plugs operate under intense pressure, heat, and chemical exposure — gradually wearing down over time and mileage.

Common Causes of Failure Include:
• Electrode wear from prolonged high-temperature operation.
• Carbon or oil fouling from incomplete combustion.
• Cracked or degraded insulators due to thermal stress.
• Incorrect heat range or plug gap settings.
• Age-related corrosion or weakened spark performance.

Failing spark plugs can cause rough idling, misfires, reduced fuel economy, and loss of power — making regular replacement essential to maintain your Porsche’s performance.
