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 Worn or outdated plugs can cause misfires, rough idle, reduced performance, and increased fuel consumption.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
