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.

Spark plugs are a vital part of the ignition system, responsible for igniting the air-fuel mixture inside each combustion chamber. Correct specification spark plugs help maintain smooth engine operation, stable idle, responsive throttle input, and efficient fuel combustion. Worn or incorrect spark plugs can lead to misfires, uneven running, reduced power, and increased fuel consumption.

Produced by Bosch, a long-established original equipment supplier to Porsche, these spark plugs are engineered with the correct heat range and electrode design for high-performance V8 engines. Their durable construction is designed to withstand high combustion temperatures and demanding operating conditions, delivering reliable ignition performance and long service life. Ideal for scheduled servicing, preventative maintenance, or restoring optimal engine performance.

Spark Plugs,
This OE Match spark plug set (pack of 8) includes six identical plugs that closely emulate Porsche original equipment in thread dimensions, electrode design, and thermal characteristics, ensuring dependable combustion and longevity. These plugs are manufactured to meet OE-equivalent standards and are ideal for use in a range of Porsche models that require this spark plug reference.
PACK OF 8

Fits:
Porsche 957 Cayenne S/GTS 4.8L 2007 - 2010
Porsche 958 Cayenne S V8 4.8L Petrol 400HP 2010 - 2017

Porsche 970.1 Panamera GTS V8 4.8L 2011 - 2016

Each spark plug is built to be durable under repeated heat cycles and high combustion pressures typical of Porsche engines. The iridium-enhanced electrode construction (when applicable) delivers consistent sparks and improved wear resistance, supporting smooth idle quality, crisp throttle response, and efficient engine performance over time.

The set is a direct-fit replacement - no modification needed - and is perfect for routine maintenance, full ignition system refresh, or when worn plugs begin to degrade performance.

These spark plugs generate precise electrical sparks within each cylinder’s combustion chamber to ignite the air-fuel mixture at the right moment. This ignition process directly influences engine smoothness, power delivery, fuel efficiency, and emissions control.

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

The spark plug generates a precisely timed electrical spark to ignite the air-fuel mixture inside the combustion chamber. The platinum-iridium construction ensures stable ignition, efficient combustion, and long-term performance consistency.

Function:
•  Produces a reliable ignition spark for efficient combustion
•  Platinum-iridium electrodes improve durability and spark consistency
•  Supports smooth idle and responsive throttle behaviour
•  Helps maintain fuel efficiency and controlled emissions

Spark plugs in air-cooled engines are exposed to high operating temperatures and sustained combustion stress. Worn or incorrect plugs can cause misfires, rough running, reduced performance, and poor fuel efficiency. Replacing worn plugs with an OE Match platinum-iridium spark plug restores stable ignition, balanced combustion, and helps preserve engine longevity and performance.

When to replace:
•  Engine misfires or uneven idle
•  Hesitation or reduced throttle response
•  Increased fuel consumption
•  At manufacturer-recommended service intervals
•  During routine engine servicing or tune-ups

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.
