BMW Intake Manifold Swirl Flap Delete Kit 22mm (4 pcs) – M47 M57 Diesel

BMW manufacturers install an EGR system in vehicles to recirculate harmful gases, but it adversely affects engine performance by sending toxic substances back into the cylinders. As a result, the power of the car is significantly reduced, wear occurs faster, and fuel consumption increases. Most often this happens upon reaching approximately 50 thousand kilometers.
