CTS TURBO BMW F-series M140i/M240i/340i/440i B58 3.0L INTAKE (2015-2018)

CTS Turbo's updated F-series B58 intake for the M140i, M240i, 340i and 440i is a full replacement for the OEM system, engineered to be the largest, highest-flowing intake available. It starts with a massive 6" velocity stack air filter and a 3.5" aluminum pipe that connects perfectly to the turbo inlet — no restrictions, no problems — plus an extra turbo heatshield to keep intake temps low. Without any extra tuning, peak gains range from 12 to 20HP (fuel and elevation dependent), and the whole kit adds power, torque and an aggressive race-inspired sound across the band. This revised version adds a more rigidly mounted inlet pipe and a better-sealing heatshield for stronger performance without a CEL.
