Perrin Front Mount Intercooler Boost Tube Kit Red 2008-2014 WRX | 2.25"-2.75" Diameter | Aluminum Boost Tubes
Overview
The Perrin Front Mount Intercooler Boost Tube Kit is a precision-engineered upgrade designed specifically for the 2008-2014 Subaru WRX. This kit replaces the factory boost tubes with larger diameter, mandrel-bent aluminum tubes that optimize airflow between the turbocharger, intercooler, and throttle body. It is ideal for WRX owners seeking to improve boost response, reduce intake restriction, and increase overall engine performance while maintaining reliability and OEM-level fitment.
Crafted with a focus on durability and efficiency, Perrin’s boost tubes feature a smooth, CNC mandrel-bent design that minimizes turbulence and pressure drop. The tubing diameter expands from 2.25 inches at the turbo outlet to 2.75 inches near the intercooler and throttle body, maximizing airflow capacity. Finished in a vibrant red powder coat, the tubes resist corrosion and add a clean, OEM+ aesthetic under the hood. The kit also includes a powder-coated coolant overflow tank and a steel intercooler support beam to enhance structural integrity and clearance for the upgraded piping.
In real-world driving, this boost tube kit delivers proven gains of 10-20+ wheel horsepower by improving charge air cooling and reducing intake restrictions. Compatible with both the stock WRX turbo and popular STI turbo upgrades, it offers versatility for various power levels. While no ECU tuning is required to enjoy immediate benefits, additional tuning can unlock further potential. This upgrade enhances throttle response, reduces turbo lag, and supports future modifications, making it a practical and effective choice for Subaru WRX enthusiasts.
