CTS Turbo Intake Kit for F2X/F3X/F87 BMW 135i/iX, M235i/iX, M2, 335i/iX, 435i/iX

After a lengthy R&D process, CTS Turbo is happy to release our new air intake system for the N55 equipped F2x/F3x/F87 BMW's!  This is the premier intake for your F2x/F3x N55.  Why?  Because almost every other intake on the market will cause poor running conditions as a result of an incorrectly shaped MAF housing.  What do we mean?  Your factory MAF housing is shaped like a hexagon, when you use a circular housing in place of the hexagon undesirable side effects occur such as incorrect MAF readings, erratic idling, and downshifting (particularly noticeable on the ZF automatic equipped cars), and last but not least POOR FUEL MILEAGE.  The reason for this is "DME" (computer) is not getting correct air flow readings due to the incorrect shape of the MAF Housing.  What did we do to fix this?  We tested developed and cast our own proprietary aluminum MAF housing in a hexagon shape to ensure that your car can meter air as well as it can in stock form.

The OEM air scoop works in conjunction with our airbox to seamlessly force cold air into our air intake system.  Air then flows through our 3.5" high flow air filter, which utilizes an inverted cone design for maximum engine breathing.  Our 3.5" CNC mandrel bent aluminum intake pipe allows for smooth entry of cold air directly into the engine, minimizing turbulence from unnecessary connections. 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.

NOTE: This intake can fit both Manual and Automatic transmission equipped cars. Fits both RWD and Xdrive models. Does NOT fit the F34 BMW 335i GT (Grand Turismo) models due to different front end/hood design. Peak power gains range from 10-15HP on an otherwise stock vehicle.
