The PERRIN Inlet Hose for the 2015-17 WRX will increase airflow to the engine which increases horsepower while adding a touch of color and style to your engine bay.
3" DIAMETER FOR MORE FLOW
The PERRIN Inlet Hose has a 3.0" internal diameter compared to 2.7" 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 Inlet Hose is perfectly smooth on the inside. Compared to the stock part, which has a very sharp bend, our PERRIN Inlet hose makes a much more gradual bend toward the throttle body making for even less restriction. This, along with removing the pleats found in the OEM hose, makes for more horsepower and improves acceleration.
The PERRIN 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 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.
