Direct-injected cars face a major drawback: carbon deposits accumulate over time, requiring regular removal. The most effective method is soda blasting, which safely and efficiently cleans the intake manifold and valves without causing damage. Unlike port-injected engines, which naturally clear deposits, direct-injected engines need this process regularly to prevent airflow restriction. Carbon buildup can lead to serious engine issues, similar to how congestion affects breathing. Symptoms of heavy carbon buildup include:
Once your intake manifold and valves are cleaned, you’ll notice a smoother idle, better fuel efficiency, improved throttle response, and potential horsepower gains.
May require an additional quotation for the renewal parts, such as injector o rings, inlet manifold gaskets etc.
