This spark plug meets the exact specifications used by Porsche on the assembly line and is fitted as standard on a range of Porsche models, ensuring precise ignition performance and long-term reliability.

Function:
•  Generates reliable ignition sparks for efficient combustion
•  Helps maintain consistent engine performance and power delivery
•  Supports smooth idle and throttle response

Spark plugs are a critical engine component that wear with use due to extreme heat, combustion pressures, and electrical stress. Worn plugs can lead to poor idle quality, misfires, reduced power, rough starts, and increased fuel consumption. Installing a genuine OE Porsche spark plug ensures the ignition system functions exactly as designed and helps preserve engine health, efficiency, and performance.

When to replace:
•  Rough or unstable engine idle
•  Misfires or engine hesitation
•  Increased fuel consumption
•  After reaching the manufacturer’s recommended service interval
•  During tune-up or ignition system servicing
