Information
Spark Plug, ZR5. Double Iridium
Double-iridium spark plugs are particularly suited to modern Porsche engines, which demand accurate ignition timing, stable combustion, and long service intervals. This design helps maintain smooth idle, crisp throttle response, efficient fuel burn, and consistent power delivery over extended mileage.
Sold individually, 4 or 6 Required per engine
Fits:
Porsche 718 (982) Boxster 2.0L 2017>> (4 Required)
Porsche 718C (982C) Cayman 2.0L 2017>> (4 Required)
Porsche 991.2 Carrera 2017 - 2019 (6 Required)
Porsche 992.1 Carrera 2019 - 2024 (6 Required)
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

Information
Spark plug, FR5DTC.
This genuine Porsche OE spark plug is the factory-installed ignition component in air-cooled and early liquid-cooled 911 Carrera and RS engines of the 964 and 993 generations. It provides the correct ignition characteristics for smooth, efficient operation, just as Porsche intended – ideal for service replacements, maintaining consistent performance and the authenticity of classic designs.
Sold individually, 12 spark plugs required per engine.
Fits:
Porsche 964 C2 / C4 1989 - 1993
Porsche 964 RS 3.6L 1991 -1993 M64.03
Porsche 993 C2 / C4 1994 - 1997
Porsche 993 C2S / C4S 1994 - 1997
Porsche 993 RS M64.20 1994 - 1997
Spark plugs are a critical part of the ignition system. Each plug creates an electrical spark inside the combustion chamber that ignites the compressed air-fuel mixture, producing the explosion that powers each engine cylinder. Genuine OE spark plugs ensure this ignition process is consistent, clean, and optimised - which supports smooth idle, strong throttle response, and efficient combustion throughout the rev range.
Functions & Technical Role:
• Ignition ignition source: Generates a reliable, timed spark for each cylinder
• Optimal combustion support: Maintains a consistent burn for power, efficiency, and emissions
• OE-matched heat range & gap: Designed to Porsche factory specifications for the 964/993 engine family
• Durable construction: Quality materials resist normal wear and combustion deposits
• High RPM performance: Suitable for classic 911 driving conditions
Spark plugs naturally wear from heat, combustion deposits, and electrode erosion. As they age, misfires, rough idle, and poorer fuel economy can develop. Installing Genuine Porsche OE plugs ensures the correct spark gap, heat range, and ignition performance, preserving engine efficiency, responsiveness, and emission stability.
When to replace spark plugs:
• At Porsche-specified service intervals
• During routine engine tune-ups or maintenance
• If experiencing misfires, hesitation, or rough idle
• When cold starting becomes harder than normal
• If performance or fuel economy drops
• While performing engine diagnostics or restoration work
