For optimal engine efficiency, Porsche recommends replacing Ignition Coils & Spark plugs 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.

High-quality OE Match double-iridium Spark Plug Set (Pack of 6). Direct-fit ignition solution for Porsche Macan (95B.1), Cayenne (958), and Panamera S (970.2), delivering long service life and OE-equivalent ignition performance.
PACK OF 6

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

Double-iridium construction is particularly beneficial in modern Porsche engines, which operate under high combustion temperatures and demand precise ignition control. This OE Match set supports smooth idle, responsive throttle behaviour, efficient fuel combustion, and consistent power delivery over extended service intervals.

Replacing spark plugs as a complete set ensures balanced ignition across all cylinders, helping maintain smooth engine operation and long-term reliability. Designed as direct replacements, these spark plugs install without modification and are ideal for routine servicing, scheduled maintenance, or ignition system refresh work.

Each spark plug generates a precisely timed electrical spark to ignite the air-fuel mixture within the combustion chamber. As a complete set, they ensure uniform combustion across all cylinders, supporting smooth running and efficient engine performance.

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 naturally degrade due to heat, combustion pressure, and electrical load. Worn or outdated plugs can cause misfires, rough idle, reduced performance, 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 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

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

Spark plugs are essential to engine operation, creating the electrical spark that ignites the air-fuel mixture inside the combustion chamber. A correctly specified spark plug helps maintain smooth engine running, stable idle, responsive throttle input, and optimal fuel efficiency. Worn or incorrect spark plugs can cause misfires, rough running, reduced power, and increased fuel consumption.

Manufactured by Bosch, a globally trusted original equipment supplier, this spark plug is produced with precise heat range and electrode design to ensure consistent ignition performance and long service life. Built to withstand high temperatures and demanding operating conditions, it delivers dependable performance for both everyday driving and high-load use.

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.

Why Replace or Upgrade Your Porsche Spark Plugs?

Replacing worn spark plugs restores full ignition efficiency, fuel economy, and responsiveness. Upgrading to performance-grade materials can also improve durability and spark precision for motorsport or tuned applications.
