Ignition Tune-Up Kit

An ignition tune-up kit includes all the parts you need to service your vehicle's ignition system. Components like spark plugs, ignition coils, spark plug connectors, and spark plug wires will eventually require replacement.

When these components are used past their useable service life you will often experience a vehicle that does not run smoothly, suffers from misfires, or even completely dead cylinders due to no spark. Replacing ignition components should be done on a regular interval

Ignition Tune-Up Kit Failure Symptoms

  • Check engine light due to misfire 
  •  P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308 and other cylinder specific misfire OBD fault codes

This iridium spark plug ignites the compressed air-fuel mixture inside the combustion chamber, enabling controlled combustion and efficient power delivery. The fine iridium electrode produces a strong, focused spark, helping turbocharged engines achieve smoother running, improved throttle response, and reliable ignition under higher cylinder pressures.

Functions & Technical Role:
•  High-energy ignition spark for efficient combustion
•  Iridium electrode technology for exceptional wear resistance
•  Improved ignition stability under turbocharged operating conditions
•  Enhanced cold starting performance
•  Reduced misfires and uneven running
•  Factory-matched heat range & gap for Porsche turbo engines
•  Longer service intervals compared to conventional spark plugs

Spark plugs are critical to combustion efficiency, especially in turbocharged engines where cylinder pressures are higher. Over time, electrode wear and carbon build-up reduce spark quality, leading to misfires, poor boost response, and reduced performance. Replacing worn plugs restores reliable ignition, protects engine components, and helps maintain smooth, consistent power delivery.

When to replace spark plugs:
•  At Porsche-recommended service intervals
•  During routine servicing or ignition system checks
•  If experiencing misfires, hesitation, or rough idle
•  When cold starting becomes more difficult
•  If boost response or performance drops
•  During engine rebuilds or restorations
•  After long-term vehicle storage before returning to use
