CTS Turbo BMW B58 Performance Intake for M140i, M240i, 340i, 440i
Part Number: CTS-IT-340
Unlock intake noise, throttle response and real power on your BMW B58 with the CTS Turbo BMW B58 Performance Intake. This is a complete replacement induction kit for the M140i, M240i, 340i and 440i F-series models. Designed to be the largest, highest flowing B58 intake on the market, it delivers proven gains and a sharper, more engaging drive.
Engineered around a massive 6 inch velocity stack cone filter feeding a 3.5 inch aluminium intake pipe that connects straight to the turbo inlet, this BMW B58 cold air intake minimises restriction for maximum flow. Sensor placement mirrors the OEM orientation for perfect readings. Twin heat shields with rubber sealing help control intake temps for consistent performance.
Expect peak gains of 12 to 20 HP without any additional tuning depending on fuel and elevation, plus a satisfying turbo spool and induction sound under load. At Nforcd we have used CTS Turbo intakes on our own B58 builds and customer cars and the feedback has been consistently excellent for both performance and sound.
