2015+ WRX 3.0" Turbo Inlet Hose by Perrin Performance.
The PERRIN Turbo Inlet Hose for 2015-2018 WRX remedies OEM vacuum leak by using a CNC billet flange (and OEM O-ring) and a large silicone hose to connect the turbo to your intake system. This eliminates the potential for vacuum leaks while increasing performance.
The OEM Subaru turbo inlet hose is smaller than the inlet of the turbo, causing an unnecessary restriction for the turbo's intake. The CNC machined flange of the PERRIN Turbo Inlet Hose has a built-in velocity stack that perfectly matches the turbo's inlet, allowing for smoother and unrestricted air flow to the turbo.
The PERRIN Turbo Inlet Hose has a 3.0" internal diameter compared to 2.6" found in the OEM part. This allows for a greater amount of air to smoothly enter your engine with virtually no restriction. This larger diameter will easily support all bolt on modifications and increased boost levels.
