BMW B58 3.0L Intake Kit for G20 M340i, G22 M440i

The CTS Turbo B58 3.0L intake for the G20 M340i and G22 M440i is a complete replacement for the factory airbox, engineered to be the largest, loudest and highest-flowing intake on the market. It starts with a massive 6" velocity stack air filter and a 4" aluminum pipe that connects perfectly to the turbo inlet — no restrictions, no problems — with the MAF sensor kept in the factory orientation for perfect readings. Without any extra tuning, peak gains range from 12 to 20HP (fuel and elevation dependent), and the kit adds power, torque and an aggressive race-inspired sound across the band.
