ARM Motorsports B58 3.75" Cold Air Intake - Various BMW / Toyota B58 Models 2016-2021
HIGHLIGHTS
• Improved Airflow
• Optional ARM Clear Cover
• Compatible with OEM or ARM Turbo Inlet
PROFILE
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!
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.
