Information
Spark plugs, FR5 NPP, Double-iridium
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 Worn or outdated plugs can cause misfires, rough idle, reduced performance, and increased fuel consumption.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

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
