CTS Turbo is proud to release the G20 BMW B58 3.0L intake for M340i. 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 filter4″ smooth air intake pipeCNC machined MAF sensor mountBlack powder coat for OEM lookTwo heat shields with rubber sealsGreat sound and power increaseAffordable price without sacrificing qualityDownload Installation Guide
