Perrin's turbo inlet hose for the stock 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 & 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.

Great quality and durability. Once i removed the old stock intake this slipped right in after lightly twisting it and all i had to do was clamp it. seen too many videos of people doing it in over 3 hours. it took me 10 mins total to install and this is my first time doing it.
Car is a 2017 STI with JDM STI TGV deletes and a Blouch Dominator 1.5 XT-R. I initially had a Cobb v1 inlet that never seemed to fit right onto the turbo neither before nor after performing the necessary modifications to the inlet length. I got frustrated fighting with the Cobb inlet and bought the Perrin and I'm glad I did. Installation wasn't bad because I wasn't fighting the OEM inlet, but I did loosen the intake manifold and 3 of 4 bolts for the TGV so I could get the inlet onto the turbo. I was able to get the inlet completely snugged up to the compressor; there's no doubt that it has a good seal. After tightening the TGV and manifold, everything stayed in place.
Exactly what i needed and fit perfect!
You can't go wrong with Perrin! Quality product as usual!
