Spark plugs are essential for creating the electrical spark that ignites the air-fuel mixture inside the engine’s combustion chamber. The correct OE spark plug delivers the right spark intensity and timing, which helps the engine start reliably, run smoothly, and produce optimal power.
Spark plugs wear over time due to electrode erosion and combustion deposits. Worn plugs can lead to misfires, rough idle, sluggish throttle response, and reduced fuel economy. Replacing them with genuine OE Porsche spark plugs ensures the correct gap, heat range, and ignition quality matched to your engine - helping maintain smooth performance and driving enjoyment.
When to replace spark plugs:
• At manufacturer-recommended service intervals
• During routine engine tune-ups
• If experiencing misfires, hesitation, or rough idle
• When cold starting becomes harder
• If fuel economy drops
• During engine diagnostics or repair work
