Swirl Flap Delete Service
At Inverness Tuning, we specialise in advanced swirl flap delete services for a wide range of diesel and petrol engines. Swirl flaps – small butterfly valves in the intake manifold – are designed to improve emissions and low-speed performance, but over time they often become a serious liability. Carbon build-up, sticking mechanisms and broken flaps can lead to poor running, limp-mode, or even catastrophic engine damage.
Our swirl flap removal and ECU recalibration eliminates these weak points and restores reliable, efficient performance.
Swirl flaps are small butterfly valves located inside the intake manifold of many modern diesel and petrol engines from brands such as BMW, Vauxhall, Land Rover, Jaguar, Saab and Fiat. Their job is to regulate and “swirl” the air entering the combustion chamber at low engine speeds. By creating a more turbulent air flow, swirl flaps can improve fuel atomisation, enhance low-RPM torque and help reduce harmful exhaust emissions. Because they are linked to the engine control unit (ECU), they open and close automatically depending on load, speed and temperature.
In real-world driving, swirl flaps help engines meet strict emissions regulations and improve drivability at lower revs. However, over time they’re prone to carbon build-up, actuator wear and even breaking off completely. This can lead to air leaks, loss of performance, fault codes, limp mode and in severe cases pieces of the flap being ingested into the engine. That’s why many owners choose a professional swirl flap delete and ECU recalibration service – to eliminate the risk, restore reliability and unlock the full performance potential of their vehicle.
A swirl flap delete is one of the most effective ways to protect and improve your diesel or petrol engine. By professionally removing the swirl flaps and recalibrating the ECU, you eliminate a major source of carbon build-up, actuator failure and potential engine damage. Drivers across Scotland choose Inverness Tuning for swirl flap removal because it delivers improved reliability, smoother airflow, better throttle response, enhanced torque, lower maintenance costs and improved fuel economy. Whether you own a BMW, Vauxhall, Land Rover, Jaguar or any other model fitted with swirl flaps, our expert service ensures your engine runs cleaner, more efficiently and without warning lights or limp-mode issues.
