We thought about modifying a TJ air intake when we found out about Airaid’s UBI (U-Build-It) 3-Inch Kit (PN 101-301). The kit comes with a series of pre-formed bends that are easily cut apart with a hacksaw, and the Master Kits include a 9-inch conical filter, clamps, couplers, reducers, and mounting hardware. After 15 minutes we were done installing our UBI on the four-banger. If we could give an award for an easy-to-use, straightforward kit, the UBI would win. We also added a pre-filter PN 799-420 to help keep dust out of the engine.
