Perrin PSP-INT-424BK 3.0" Turbo Inlet Hose with Nozzle (WRX 2015+)

OVERVIEW
The PERRIN Turbo Inlet Hose for the 2015-2018 WRX will increase airflow to the engine which increases horsepower while adding a touch of color and style to your engine bay.

NO TUNING REQUIRED!

WHY YOU NEED THIS
The plastic intake manifold constantly flexes under normal driving conditions.  Over time, the flange will compress and deform causing vacuum leaks at the turbo.  This leads to dangerous engine conditions and check engine lights.  The PERRIN Turbo Inlet Hose for 2015-2018 WRX remedies this 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.

PROPER INLET-TO-TURBO ALIGNMENT
The OEM Subaru turbo inlet hose is smaller than the inlet of the turbo, causing 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.

3" DIAMETER FOR MORE FLOW
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.

SMOOTHER AIR FLOW
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.

WIRE REINFORCEMENT
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.

FORM AND FUNCTION
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.
