Excessive carbon buildup can accumulate in areas like the intake manifold, throttle body, and fuel injectors. This can lead to:

Poor acceleration.
Increased emissions.
Rough idling and engine knocking.

How often to clean:

Depending on driving habits, cleaning the intake system and fuel injectors every 30,000 to 40,000 km is recommended.
