The ARM B58 Intake is not another B58 lookalike. ARM built it around 3.75" piping the whole way through, making it the largest B58 intake available and feeding the turbo more air than OEM or the typical aftermarket kit. On a serious build, it keeps the intake from being your bottleneck.
It uses an inverted filter design with a big filter surface area and a multimedia element that breathes well without giving up filtration. The filter sits inside an aluminum heat shield that keeps engine heat off your intake charge, and it comes with a powder coated black aluminum cover or an optional clear cover if you want to show it off. Both look right at home in the B58 bay. The T6061 aluminum MAF pipe runs a full 3.75" front to back, around 14% wider than OEM, and ties into the inlet through a 6 layer reinforced silicone coupler so the path stays wide and smooth from filter to turbo.
It bolts to the factory turbo inlet, or pair it with the ARM B58 Turbo Inlet for a complete induction setup that supports the most demanding builds. Everything needed for the install is in the box: filter, heat shield and cover, MAF pipe, silicone coupler, and clamps.
