What's in the Box
If you can imagine a custom intake system, now you can build it! The U-Build-It (UBI) kit is the most versatile custom intake system on the market. AirAid offers their master kits, which include everything you need to build a complete system, and all components are also available individually for maximum adaptability. Whether you are doing an engine swap or have a custom application where space is tight, the AIRAID® UBI Intake System can accommodate just about any application. The only limitation is your imagination!
While a UBI master kit is recommended for anyone building a custom intake system from scratch, sometimes completing a custom intake might require a few extra couplers, or perhaps an extra bend. To address this, AIRAID® offers all of the UBI components individually. All of the UBI intake tube straights and bends are available as individual pieces, as well as couplers, hump hoses, clamps, filter adapters, and so on. AIRAID® also has a wide selection of filters in different sizes that are compatible with all of the UBI systems. Air system tubes available in 3", 3-1/2", and 4" diameters.
