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
