The Perrin turbo 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 hose is wire-reinforced so it wont suck close under boost.
No ECU tuning required!
Choose from red or black hose color.
Fits all 2015-2021 Subaru WRX and 2014-2018 Forester XT.
