Does removing swirl flaps increase power?
In normal driving the swirl flaps are open, the shortest route, so by removing the complete flap there is little to no performance difference felt when driving the vehicle.
What happens when swirl flaps fail?
When a swirl flap fails, the debris drops down into the engine, either sticking in the valve port and jamming it open, causing the piston to collide with the valve, or falls into the cylinder itself causing the piston, valves and head to become damaged.
What do swirl flaps do in an engine?
Swirl flaps produce a swirl alongside the cylinder axle. They are used in diesel vehicles to improve the mixing of the fuel-air mixture at low engine speeds. For this purpose, the air is fed to each cylinder through two separate channels in the intake manifold. One of the two channels can be closed with a swirl flap.
Will removing swirl flaps affect emissions?
The swirling affect aids combustion and helps to generate a leaner air to fuel ratio. After 2000 rpm the flaps are generally activated to a fully open position and have very little effect on engine performance and emissions.
Are swirl flaps necessary?
This main purpose of using swirl flaps in the engines is to ensure the proper mixing of fuel and air at low speeds so by lengthening the route of air entering the cylinder head, swirling the air inside the combustion chamber. This ‘swirling’ of air creates a better fuel-air mixture and improves efficiency.
Can you clean swirl flaps?
Cleaning your Intake Manifold and Swirl Flaps The moderately expensive alternative is to if possible manually clean them. Most mechanics will recommend this – Why? Because they’ll earn well from the extensive hours it takes to complete the job.

Do petrol cars have swirl flaps?
Swirl flaps are small butterfly valves located within the inlet manifold on modern diesel and petrol engines, they are designed to help regulate the fuel to air ratio, improve emissions and help generate better torque at low engine speeds.
