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. These hoses are wire-reinforced so they wont suck close under boost. Choose from red, blue, or black color.
Fits all 2015+ WRX.
