Swirl flap failure is a well-known issue on BMW N47 and N47S engines, with the potential to cause serious internal engine damage. Removing the swirl flaps is a proven preventative upgrade to improve long-term reliability and peace of mind.
Our kit is designed and manufactured using the best quality components to ensure durability and performance. It includes precision CNC-machined block-off plug for a perfect fit, along with new Permaseal intake manifold gaskets to guarantee a proper, leak-free seal.
