What are the flaps / swirls valves?
The swirls valves (or flow control valves) are present in the intake manifold and are fairly widespread in modern engines. Their function is to regulate the amount of air-fuel mixture according to the engine speed and other factors, similar to that of the electronic throttle valve.
I have to replace the swirl valves, can i exclude them?
The swirl valves are quite delicate, many vehicles have problems that cause the malfunction and the error in the control unit. With this change, you can exclude the operation of swirl valves and save on a new unit and workmanship costs. The vehicle will not experience any abnormality, and the problem will not occur again in the future.
