PERRIN 08-14 Subaru STI Front Mount Intercooler Boost Tubes + Hardware - Red Tubes

The smooth, mandrel-bent aluminum tubing in this Perrin boost tube kit is a key detail for your 2008-2014 Subaru Impreza STI. These tubes replace the restrictive factory piping that connects your intercooler to the throttle body. By using larger diameter, smoother flowing pipes, you help your turbocharger push more air into the engine, which can lead to improved throttle response and more consistent power delivery, especially when you've upgraded your turbo or intercooler.

Perrin builds these tubes from thick-walled aluminum, and they're mandrel-bent to ensure consistent diameter throughout the bend, avoiding any kinks that could disrupt airflow. The red powder-coated finish not only looks sharp under the hood but also adds a layer of durability. This kit comes with all the necessary hardware, including high-quality silicone couplers and T-bolt clamps, to make installation straightforward. These clamps provide a strong, leak-free seal that you can rely on, even under boost pressure. This is a popular upgrade for STI owners looking to maximize the efficiency of their forced induction system.

When installing this kit, pay close attention to how the silicone couplers are positioned before tightening the T-bolt clamps to ensure a secure fit. This kit is designed as a direct replacement for the stock intercooler piping, making it a solid choice for anyone looking to get more performance out of their STI's engine. Please note that this part is not CARB approved and cannot be shipped to California.
