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

The spark plug produces a precisely timed electrical spark to ignite the air-fuel mixture in the combustion chamber. The double-iridium construction ensures a strong, stable spark and reduced electrode wear, supporting efficient combustion and reliable engine performance. The use of iridium on both the centre and ground electrodes allows for a finer electrode tip, improving spark efficiency while significantly increasing resistance to wear under extreme heat and combustion pressure.
Engineered as a direct replacement, this spark plug installs without modification and is ideal for routine servicing, scheduled maintenance, or replacement of individual plugs while maintaining OE-level performance.
Function:
• Generates a consistent ignition spark for efficient combustion
• Double-iridium electrodes improve durability and spark stability
• Supports smooth idle and responsive acceleration
• Helps maintain fuel efficiency and emission control
Standard spark plugs wear over time, which can lead to misfires, rough running, reduced performance, and increased fuel consumption. A double-iridium OE Match spark plug offers enhanced durability and longer service life, helping maintain consistent ignition performance and protecting ignition coils and catalytic converters from damage caused by incomplete combustion.
When to replace:
• Engine misfires or uneven idle
• Reduced throttle response or loss of power
• Increased fuel consumption
• Manufacturer’s recommended maintenance interval reached
• During routine tune-up or ignition system servicing
