CTS TURBO BMW G20 M340i/G22 M440i/G42 M240i B58 3.0L INTAKE

CTS Turbo is proud to release the BMW B58 3.0L intake for G20 M340i/G22 M440i. Our intake kit is a complete replacement for the factory airbox system. The design intent was to create the largest, loudest and highest-flowing intake on the market. Starting with a massive 6" velocity stack air filter, the intake features a 4" 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. 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 6" velocity stack reusable air filter
• 4" smooth air intake pipe
• CNC machined MAF sensor mount
• Black powder coat for OEM look
• Great sound and power increase
• Affordable price without sacrificing quality
