The ARM B58 Intake isn't your standard lookalike B58 intake, this has been designed with upgraded 3.75" piping throughout, making it the largest B58 intake available.  Combine the ARM B58 Intake with the ARM B58 Turbo Inlet to give your B58 a complete induction solution capable of supporting the most demanding B58 builds!

B58 Intake


The ARM B58 Intake utilizes an inverted filter design which gives it a massive 186 cubic inches of surface area.  Paired with a multimedia filter material which allows for superb airflow while providing impressive filtration and you have a combination that can take your B58 build wherever you want it to go. 

 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.
