The ARM B58 Turbo Inlet significantly enhances turbo performance for the Gen 1 B58 engine by increasing the turbo inlet diameter by 25% compared to the factory unit. A standout feature of the ARM B58 Inlet is its 2.5” inside diameter at the turbo snout—substantially larger than the OEM's 2.0” diameter—resulting in a substantial improvement in airflow.
By eliminating the factory sound mufflers, the ARM Turbo Inlet reduces air turbulence and promotes a smoother, more consistent flow into the compressor turbine. This results in faster turbo spool, improved throttle response, and increased power and torque across the powerband.
Designed as a direct-fit upgrade, the ARM B58 Turbo Inlet includes all necessary hardware to maintain full compatibility with OEM fittings.
PREMIUM CONSTRUCTION
Engineered for both performance and reliability, the ARM B58 Turbo Inlet begins with a CNC-machined aluminum fitting that integrates seamlessly with the OEM O-ring and C-clip, ensuring a secure and leak-free connection at the turbo snout.
The inlet body is constructed from 6-layer reinforced high-temp silicone, built to withstand extreme engine bay temperatures and maintain structural integrity.
At the intake side, the inlet expands to a 3.75" inner diameter, and includes a precision adapter for use with either the OEM intake or the ARM B58 Intake system, which maintains a full 3.75" diameter to the air filter for optimal airflow.
