Enlarged Turbo Inlet Elbow Intake Hos with K&N panel filter. For B58 BMW M140i M240i 340i 440i. The B58 turbo inlet/intake pipe for BMW B58 engines is compatible with the standard intake systems. It represents a very important component between the turbocharger and the intake system, because only if the entire path to the turbocharger is optimised can the full potential of the turbocharger and engine be made available. The new intake manifold has been developed to provide maximum throughput and optimum flow, delivering a sensational increase of +41% more airflow. The original component is restrictive and also has flow-restrictive edges This is not designed for performance, but actually creates turbulence and back pressure. Only in this way can the air reach the turbocharger in an optimal and even flow pattern. The results are a higher maximum power, an improved response and an increased intake noise. Consisting of a flange and a hose. Enables a higher final power output and improved responsiveness.
