Product Information
OE Match iridium spark plug set (Pack of 4) is designed to replicate the original Porsche factory spark plugs in fit, heat range, and ignition performance. Supplied as a complete set of four, it is specifically suited to the Porsche 924 Turbo (1979–1985).
PACK OF 4
Fits:
Porsche 924 2.0 Turbo 06.80 - 10.86 130kw 177hp Engine type M31.03
This OE Match iridium spark plug set includes four identical spark plugs, each manufactured to OE-equivalent standards for thread dimensions, electrode design, and thermal performance. The iridium-tipped electrode provides a finer spark point and superior resistance to wear compared to standard spark plugs, ensuring stable ignition and consistent combustion over extended service intervals.
Porsche turbocharged engines operate under increased heat and pressure, making spark plug quality critical. This OE Match set helps maintain smooth idle, responsive throttle behaviour, and efficient fuel burn while supporting reliable performance under boost. Supplied as a complete set, it ensures balanced ignition across all cylinders and uncomplicated installation with no modification required.
Each spark plug generates a precisely timed electrical spark to ignite the air-fuel mixture in its cylinder. As a full set, they ensure uniform combustion across all four cylinders, supporting smooth engine operation and consistent turbocharged performance.
Function:
• Produces a reliable and consistent ignition spark
• Iridium electrodes improve durability and spark stability
• Supports smooth idle, responsive throttle, and efficient combustion
• Direct replacement for compatible Porsche applications
Spark plugs naturally wear over time due to repeated heat cycles, combustion stress, and electrical load. Worn plugs can lead to misfires, rough idle, reduced power, and increased fuel consumption. Choosing an OE Match iridium spark plug helps maintain consistent ignition performance, prolonged component life, and dependable running characteristics that match the original factory intent.
When to replace:
• Engine misfires or rough idle
• Hesitation under acceleration
• Increased fuel consumption
• At manufacturer-recommended service intervals
• During routine tune-ups or ignition system servicing

This iridium spark plug ignites the compressed air-fuel mixture inside the combustion chamber, enabling controlled combustion and efficient power delivery. The fine iridium electrode produces a strong, focused spark, helping turbocharged engines achieve smoother running, improved throttle response, and reliable ignition under higher cylinder pressures.
Functions & Technical Role:
• High-energy ignition spark for efficient combustion
• Iridium electrode technology for exceptional wear resistance
• Improved ignition stability under turbocharged operating conditions
• Enhanced cold starting performance
• Reduced misfires and uneven running
• Factory-matched heat range & gap for Porsche turbo engines
• Longer service intervals compared to conventional spark plugs
Spark plugs are critical to combustion efficiency, especially in turbocharged engines where cylinder pressures are higher. Over time, electrode wear and carbon build-up reduce spark quality, leading to misfires, poor boost response, and reduced performance. Replacing worn plugs restores reliable ignition, protects engine components, and helps maintain smooth, consistent power delivery.
When to replace spark plugs:
• At Porsche-recommended service intervals
• During routine servicing or ignition system checks
• If experiencing misfires, hesitation, or rough idle
• When cold starting becomes more difficult
• If boost response or performance drops
• During engine rebuilds or restorations
• After long-term vehicle storage before returning to use

Manufactured to OE-equivalent standards, it delivers reliable performance under high heat and pressure conditions typical of Porsche engines. Its direct-fit design ensures proper thread engagement, correct heat range, and uncomplicated installation without modification. This plug is ideal for routine servicing, tune-ups, or replacing a worn plug while maintaining balanced engine operation.
The spark plug creates a precisely timed electrical spark inside the combustion chamber to ignite the air-fuel mixture. This controlled ignition supports smooth engine operation, efficient fuel burn, and consistent power delivery across the RPM range.
Function:
• Produces a reliable and consistent ignition spark
• Iridium electrodes improve durability and spark stability
• Supports smooth idle, responsive throttle, and efficient combustion
• Direct replacement for compatible Porsche applications
Spark plugs naturally wear over time due to repeated heat cycles, combustion stress, and electrical load. Worn plugs can lead to misfires, rough idle, reduced power, and increased fuel consumption. Choosing an OE Match iridium spark plug helps maintain consistent ignition performance, prolonged component life, and dependable running characteristics that match the original factory intent.
When to replace:
• Engine misfires or rough idle
• Hesitation under acceleration
• Increased fuel consumption
• At manufacturer-recommended service intervals
• During routine tune-ups or ignition system servicing

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.
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.
Key Benefits:
• Restores smooth acceleration and idle stability.
• Improves fuel efficiency and throttle response.
• Reduces misfires, vibration, and engine hesitation.
• Available in platinum, iridium, and copper-core configurations.
