Description
Unlock your BMW B58 engine’s full potential with the Forge Motorsport Silicone Inlet Hose – engineered for performance, precision, and durability. This high-flow five-ply silicone inlet hose replaces the restrictive OEM component, eliminating the factory sound resonator and turbulence-causing accordion ribs. The result is smoother airflow, improved induction noise, and measurable performance gains.
Dyno-proven gains include:
-
+9 BHP and +7 Nm of torque at peak RPM
-
Enhanced throttle response and turbo spool
-
Improved induction sound for a sportier driving experience
Built to withstand higher temperatures and pressure, this hose features a reinforced 5-ply construction with a 90mm internal diameter at the airbox end (vs. OEM’s 85mm), and includes a reducer to ensure a secure OEM-style fit. It’s compatible with both OEM and aftermarket intake systems.
