CONSTRUCTION
The filter in the ARM B58 Intake is protected from excessive engine heat by the aluminum heat shield surrounding it. This heat shield comes standard with the powder coated black aluminum cover, or the optional ARM clear cover. Both options look right at home in the B58's engine bay.

The T6061 aluminum MAF pipe is a full 3.75" throughout, 14% larger than OEM and similar aftermarket intakes for the B58, providing more airflow to the B58's turbo.

The ARM B58 MAF pipe is connected to the B58 inlet via the 3.75" 6-layer reinforced silicone coupler. The ARM B58 Intake is designed to connect to either the OEM turbo inlet or for maximum airflow the ARM B58 Turbo Inlet.
