High-Flow Intake Kit

The CTS Turbo High-Flow intake kit is designed to be a comprehensive upgrade for your BMW's factory airbox system, targeting models equipped with the S63TU4/N63T3 4.4L twin-turbo engine. The development focused on maximizing flow and sound, aiming to make your twin-turbo V8 engine sound and perform like a fighter jet. Key features include massive 6-inch velocity stack reusable air filters and smooth 3-inch aluminum intake pipes with a black powder coat finish for an OEM look. The kit comes with two sets of couplers to accommodate both Competition and standard model fitments. Without requiring additional tuning, this intake system can provide peak power gains ranging from 12 to 20HP, depending on fuel and elevation, along with an aggressive race-inspired exhaust note. This high-flow intake system is specifically designed to fit the following BMW models: 2018+ F90 M5/M5C/M5CS, 2020+ F92 BMW M8/M8C, 2020+ F93 BMW M8/M8C, 2020+ G30 BMW M550I (LCI models only), 2019+ G15 BMW M850I, and 2019+ G16 BMW M850I. It is important to note that this kit does not fit the G11 BMW 750i due to the presence of additional strut braces in that model.
