This OE Match double-iridium spark plug set includes eight identical spark plugs, each manufactured to OE-equivalent standards for thread dimensions, electrode design, and thermal characteristics. Featuring iridium on both the centre and ground electrodes, these plugs provide a finer, more stable spark and significantly increased resistance to wear compared to conventional spark plugs.

Turbocharged Porsche V8 engines operate under extreme temperatures and cylinder pressures, placing high demands on ignition components. This OE Match set supports consistent ignition, smooth idle, responsive throttle behaviour, and efficient combustion under boost. Replacing all eight spark plugs together ensures balanced ignition across cylinders and reliable performance throughout the rev range.

Designed as direct replacements, these spark plugs install without modification and are ideal for routine servicing, scheduled maintenance, or ignition system overhaul on high-performance Porsche turbo models.

Each spark plug produces a precisely timed electrical spark to ignite the air-fuel mixture in its cylinder. As a complete set, they ensure uniform combustion across all eight cylinders, supporting smooth engine operation, strong turbo response, and consistent power delivery.

Function:
•  Provides reliable ignition for all eight cylinders
•  Double-iridium electrodes enhance spark stability and durability
•  Supports smooth idle and responsive acceleration
•  Helps maintain power delivery, fuel efficiency, and emissions control

Spark plugs in turbocharged V8 engines are exposed to extreme heat and pressure. Worn plugs can cause misfires, hesitation under boost, reduced power, and increased fuel consumption. Replacing all eight plugs with an OE Match double-iridium set restores reliable ignition, balanced combustion, and helps protect ignition coils, catalytic converters, and engine components.

When to replace:
•  Engine misfires or rough idle
•  Hesitation under acceleration
•  Reduced throttle response or power delivery
•  Increased fuel consumption
•  At manufacturer-recommended service intervals
•  During routine engine tune-ups or ignition servicing
