CTS Turbo High-Flow intake kit for BMW F90/F92/F93/G30/G15/G16 M5/M5C/M5CS/M8/M8C/M850i/M550i

CTS Turbo is proud to release our high-flow intake kit for BMW S63TU4/N63T3 4.4L twin-turbo engine commonly found in BMW F90/F92/F93/G30/G15/G16 M5/M5C/M8/M8C/M850i/M550i. 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. You got a twin turbo V8 - now, make it sound like a fighter jet (and go like one). Starting with a massive 6″ velocity stack air filters, the intake features a 3″ aluminum pipe that connects perfectly to the turbo inlets. 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. Without any extra tuning, peak power gains range from 12 to 20HP (fuel and elevation dependent). Features:

• Massive 6″ velocity stack reusable air filters
• 3″ smooth air intake pipes
• Black powder coat for OEM look
• Two sets of couplers for fitment with Competition and standard models.
• Great sound and power increase
• Affordable price without sacrificing quality
