CTS Turbo is proud to release the F-series BMW B58 3.0L intake for M140i/M240i/340i/440i. Our intake kit is a complete replacement for the OEM system.

The design intent was to create the largest, highest flowing intake on the market.

Starting with a massive 6″ velocity stack air filter, the intake features a 3.5″ aluminum pipe that connects perfectly to the turbo inlet. No restrictions, no problems. MAF sensor is placed into same orientation as from factory to provide perfect readings.

We also added 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.

Features:

• Massive velocity stack reusable air filter
• 3.5″ smooth air intake pipe
• CNC machined MAP sensor mount
• Black powder coat for OEM look
• Two heat shields with rubber seals
• Great sound and power increase
• Affordable price without sacrificing quality
