CTS Turbo Intake | 2015-2018 BMW M140i, M240i, 340i & 440i

Upgrade the factory B58 intake system with a high-flow CTS Turbo intake designed for improved airflow, sharper response, and a more aggressive induction sound. The system replaces the OEM intake with a large 6-inch velocity-stack filter and a 3.5-inch aluminum intake pipe leading to the turbo inlet.

The intake includes a CNC-machined MAF housing, two heat shields with sealing rubber, and a rigidly mounted inlet pipe. The heat-shield design helps reduce exposure to engine-bay heat while the larger filter and intake tract support increased airflow.

Features: 6-inch reusable velocity-stack filter, 3.5-inch aluminum intake pipe, CNC-machined MAF mount, black powder-coated finish, dual heat shields, and compatibility with factory or aftermarket turbo inlet pipes.

Fitment: 2015-2018 BMW M140i, M240i, 340i and 440i. Does not fit 2019+ G20 340i/M340i applications.
