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

Spark plug WR 7 DC+
Genuine OE Porsche spark plug, factory-engineered to deliver precise ignition performance, efficient combustion, and reliable operation. Direct replacement part maintaining original Porsche ignition standards.
Sold individually, 4, 6 or 8 required depending on engine type
Fits:
Porsche 911 3.2L 1984 - 89 *with catalyst
Porsche 924S 2.5L 1986 - 1988
Porsche 928S / 928S2 / 928S4 / 928GT 1983 - 1991
Porsche 944 / 944S / 944S2 / 944T 1985 - 1991
Porsche 912E 1976
Porsche 968 1992 - 1995 Coupe
Porsche engines rely on accurate ignition timing and stable combustion, especially under high compression and performance conditions. Using a genuine Porsche spark plug helps maintain smooth idle, crisp throttle response, optimal power delivery, and controlled emissions. It also ensures compatibility with Porsche engine management systems and ignition coils.
Designed as a direct replacement, this spark plug installs without modification and is suitable for routine servicing, diagnostics, or replacement of individual worn plugs while maintaining full OE integrity.
The spark plug generates a precisely timed electrical spark inside the combustion chamber to ignite the air-fuel mixture. This controlled ignition initiates combustion, allowing the engine to produce power efficiently and smoothly.
Function:
• Produces a consistent ignition spark for efficient combustion
• Supports smooth idle, responsive acceleration, and stable power output
• Helps maintain fuel efficiency and emission control
• Engineered to Porsche’s exact OE heat range and performance standards
• Designed for durability under high thermal and mechanical loads
Spark plugs naturally wear due to heat, combustion pressure, and electrical stress. A worn or incorrect spark plug can cause misfires, rough running, reduced power, increased fuel consumption, and higher emissions. Replacing worn plugs with a genuine Porsche OE spark plug ensures the ignition system continues to perform exactly as engineered, protecting engine performance, efficiency, and longevity.
When to replace:
• Engine misfires or uneven idle
• Reduced throttle response or loss of power
• Increased fuel consumption
• At Porsche-recommended service intervals
• During routine engine servicing or ignition maintenance

Information
Spark plug WR4CC.
Original Equipment spark plug manufactured by Porsche to the factory specification for the ignition system. A spark plug’s core function is to ignite the compressed air-fuel mixture inside each cylinder of the engine. It produces a controlled electrical spark at exactly the right moment, initiating combustion to deliver efficient power output and smooth engine performance.
Sold individually, 6 Required per engine.
Fits:
Porsche 911 3.2L Carrera 1984 - 1989
* Non Catalyst
Functions & Technical Role:
• Ignition ignition source: Generates spark for combustion on demand.
• Engine performance stability: Supports consistent firing across all cylinders.
• Fuel efficiency and emissions: Proper spark timing improves combustion and helps maintain efficient fuel use.
• Engine durability: Correctly specified plugs prevent misfires and reduce stress on ignition components.
• Plug Type: WR4CC, factory-recommended use.
Spark plugs are critical to efficient combustion and smooth engine performance. Over time, wear, carbon build-up, and heat cycling reduce spark strength, leading to misfires, poor throttle response, and increased fuel consumption. Replacing worn spark plugs with Genuine Porsche OE parts restores correct ignition timing, protects engine components, and keeps your 911 running as Porsche intended.
When to replace spark plugs:
• At manufacturer-recommended service intervals
• During routine engine servicing or tune-ups
• If experiencing misfires, rough idle, or hesitation
• When starting becomes harder than normal
• If fuel economy decreases
• During engine rebuilds or restoration work
• After prolonged storage before returning the car to use
