Swirl flaps are small valves located within the inlet manifold of modern diesel and petrol engines. They play a role in regulating the fuel and air ratio, improving emissions, and generating better torque at low engine speeds.

During engine operation, the swirl flaps close, causing the air to swirl into the combustion chamber. This swirling effect helps enhance emissions and increase torque. After reaching approximately 2000 rpm, the flaps are fully open and have minimal impact on engine performance or emissions.

Failed swirl flaps can lead to various issues, including major mechanical failure, leaking manifolds, carbon build-up, and malfunctioning electronic actuators.

If you are experiencing any of these issues, a cost-effective solution is to remove the swirl flaps. The process of removing the flaps varies depending on the vehicle, but typically involves unbolting the manifold and physically removing the flaps. Additionally, the ECU is mapped to reflect these changes.

By removing the swirl flaps, you can address these common faults and improve the performance and reliability of your vehicle. Consult with our experts to determine the best course of action for your specific vehicle.
