PERRIN 02-07 Subaru WRX/STi Front Mount Intercooler Boost Tubes + Hardware w/Red Tubes

These Perrin boost tubes are made from thick-walled aluminum, measuring 2.5 inches in diameter. This specific design choice helps maintain consistent airflow from your turbocharger to your front-mount intercooler, which is crucial for keeping intake air temperatures down. For the 2004-2007 Subaru Impreza WRX and STi, upgrading from the stock rubber or plastic piping to these smooth, rigid aluminum tubes can make a notable difference in how your turbo system performs. The stock piping can sometimes collapse under boost, but these Perrin tubes are built to resist that, ensuring your turbo can push air effectively.

The kit includes everything you need to get these installed, featuring silicone couplers and stainless steel T-bolt clamps. The red silicone couplers not only provide a secure seal but also add a splash of color under the hood, complementing the red powder-coated finish on the aluminum tubes themselves. Perrin is known for making well-built parts for Subarus, and this intercooler piping kit is no exception. It’s designed to fit right in place of your factory piping, making the installation process more straightforward for someone familiar with working on their car.

When you're looking to get the most out of your turbocharged Subaru, ensuring that the air is moving efficiently is key. These boost tubes are a solid step towards optimizing your intercooler system. Remember that this part is not CARB approved and cannot be shipped to California.
