Spark Plugs (PACK OF 8). Porsche 957 Cayenne / 958 Cayenne / Panamera V8  ❭  99917013090

Each spark plug is built to be durable under repeated heat cycles and high combustion pressures typical of Porsche engines. The iridium-enhanced electrode construction (when applicable) delivers consistent sparks and improved wear resistance, supporting smooth idle quality, crisp throttle response, and efficient engine performance over time.

The set is a direct-fit replacement — no modification needed — and is perfect for routine maintenance, full ignition system refresh, or when worn plugs begin to degrade performance.

These spark plugs generate precise electrical sparks within each cylinder’s combustion chamber to ignite the air-fuel mixture at the right moment. This ignition process directly influences engine smoothness, power delivery, fuel efficiency, and emissions control.
