Perrin’s turbo inlet hose for the stock Subaru WRX and STi features 5-ply silicone construction with a wire mesh for maximum durability. Silicone construction means extreme resistance to heat soak, and a smooth internal passageway, unlike the corrugated rubber stock Subaru WRX and STi inlet.
The 3in turbo inlet is made for bigger than stock turbos and will not fit the factory one. If you’ve upgraded your turbo then it’s a great idea to upgrade your turbo inlet. This allows for freer and more air to enter the system ultimately creating more power. 2.4 inch on back order frequently please check with IIR sales rep if you need it quickly before ordering! 5/13/10 update, 10 in stock!Perrin’s silicone construction ensures the maximum possible tube diameter is utilized, and the non-corrugated interior allows for optimal airflow; opening up the intake tract and making more power!
The 3in turbo inlet WILL NOT fit the factory turbo.
