CTS air intake kit, BMW B58 M140 / M240 / 340 / 440

CTS Turbo solution for the famous F-series BMW B58 3.0L engine found in M140i/M240i/340i/440i. This intake kit is a complete replacement for the OEM system. The CTS design intent was to create a extremely high flowing intake on the market.

Starting with a massive 6 inch velocity stack air filter, the intake features a 3.5 inch aluminum pipe that connects perfectly to the turbo inlet. No restrictions, no problems. Additionally there’s an extra turbo heatshield in order to keep air intake temperatures as low as possible.

Without any extra tuning, peak power gains range from 12 to 20HP (fuel and elevation dependent). All of the components included in the CTS air intake system work flawlessly together to provide increased horsepower and torque throughout the entire power band and an aggressive race-inspired sound.

This new revised version features a more rigidly mounted inlet pipe and a better sealing heatshield for superior performance without a CEL.
