Perrin Performance 3.0" Turbo Inlet Hose with Nozzle for 2015-2018 WRX

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.

The PERRIN Turbo Inlet Hose is perfectly smooth on the inside. The OEM turbo inlet has sharp bends, corrugated ribbing, and strange pockets, all of which disturb airflow. The PERRIN Turbo Inlet Hose is much smoother, with more gradual bends toward the turbo making for less restriction leading to increased horsepower and improved acceleration. Not only does the PERRIN Turbo Inlet Hose provide superior airflow from your intake for increased power and throttle response, it will look great doing so. The clean and smooth look of the hose will help to clean up your engine bay.

The PERRIN Turbo Inlet Hose is reinforced with a stainless steel support wire that is embedded within the silicone layers. The support adds rigidity to the hose and prevents collapses when used with restrictive filter elements and high horsepower setups.
