PERRIN 02-07 Subaru WRX Boost Tube #5 Long 4 Bend 2.75in w/ BOV Fitting - Wrinkle Red

If you're looking to improve the airflow to your intercooler on your 2002-2007 Subaru WRX, this Perrin boost tube is a solid option. This is the fifth tube in their kit, designed to replace the stock piping that can sometimes be a bottleneck for air moving from the turbocharger to the intercooler. Getting more air to your intercooler means it can do a better job of cooling the charge air before it goes into the engine, which is key for consistent power, especially when you're pushing your turbo harder.

Perrin makes these tubes from aluminum with a wrinkle red powder coat finish. The 2.75-inch diameter is a common size for improved airflow, and the 4-bend design helps it fit cleanly in the engine bay. It also includes a fitting for a blow-off valve, so you can easily connect your aftermarket BOV if you have one. This part is designed to fit right into your existing intercooler piping setup, making the installation straightforward for someone familiar with turbo system components.
