MAD F Chassis B58 Turbo Inlet Upgrade for BMW F2X M140 240 F3X 340 440 MAD introduces their F-chassis B58 BMW Turbo Inlet/Resonator Delete Pipe, a product designed to optimize airflow from the intake to the turbo, eliminating restrictions and increasing the inlet diameter for improved power and turbo efficiency. The MAD F-chassis turbo inlet pipe offers a seamless replacement for the factory OEM unit. The OEM turbo inlet in plastic construction is prone to pressure-related cracks and features a flow-hindering "resonator." Additionally, the factory piping has a smaller diameter that hinders performance. MAD's Aluminum F-chassis B58 Turbo Inlets provide a wider diameter and eliminate the factory resonator, resulting in smoother and more direct airflow to the turbo, along with an enhanced induction sound.
