There are 2 reasons to change your factory turbo inlet pipe on the Subaru WRX and STI cars. First reason is the factory inlet pipe is very restrictive. Its thin diameter and corregated design reduces air flow and robs your car of horsepower. The second reason is the factory inlet pipe is a very cheap plastic material. When you upgrade to a new turbo, this pipe tends to crack or not fit on the new turbo during installation. Agency Power has brought you the best solution of a new turbo inlet pipe for your Subaru WRX or STI vehicle. This all stainless steel intake pipe is a full 3 inch in diameter.
