Product 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
