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

Designed as a direct replacement for both 99917023590 and the earlier 99917023390, this spark plug installs without modification and is ideal for routine servicing, scheduled maintenance, or replacement of worn ignition components.

Spark plugs play a vital role in the engine’s ignition system by producing the electrical spark that ignites the air-fuel mixture in each cylinder. Proper ignition ensures smooth engine starting, efficient combustion, and stable performance across idle and load conditions. This OE spark plug ensures the correct heat range, electrode design, and spark characteristics Porsche engineers specified for optimal combustion performance.

• Routine engine servicing and ignition tune-ups
• Replacing worn or fouled spark plugs to restore smooth performance
• Ignition system refresh during diagnostic work
• Routine maintenance to support fuel economy and emissions performance
• OEM part fit for restorations or warranty-compliant repairs

Spark plugs gradually wear due to heat, carbon build-up, and electrode erosion. As they age, the spark can weaken and combustion becomes less efficient, leading to rough idle, hesitation, poorer fuel economy, and increased emissions. Replacing plugs with Genuine Porsche OE spark plugs ensures correct gap, heat range, and ignition performance - preserving engine smoothness and power delivery to factory levels.

When to replace:
•  At manufacturer-recommended service intervals
•  During routine ignition system servicing
•  If experiencing misfires, rough idle, or hesitation
•  When engine starting becomes inconsistent
•  If fuel economy drops or emissions increase
•  During engine diagnostics or rebuild work
