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 designed specifically for the 2008-2014 Subaru WRX, offering a high-flow, durable solution for your turbocharged intake system. This kit replaces restrictive factory boost tubes with CNC mandrel bent aluminum tubes that increase airflow efficiency between the turbocharger, intercooler, and throttle body. Ideal for WRX owners looking to optimize boost response and overall engine performance without compromising reliability or fitment.

Engineered with precision, Perrin’s boost tubes feature a smooth, mandrel-bent design that minimizes turbulence and pressure drop. The tubes increase in diameter from 2.25 inches at the turbo outlet to 2.75 inches near the intercooler and throttle body, ensuring maximum airflow capacity. Powder coated in vibrant red, these tubes not only resist corrosion but also add a clean, OEM+ aesthetic under the hood. The kit also includes a new coolant overflow tank and a robust steel intercooler support beam, designed to improve durability and clearance for the upgraded piping.

Real-world benefits include a proven 10-20+ wheel horsepower gain thanks to improved charge air cooling and reduced intake restriction. The boost tube kit is compatible with both the stock WRX turbo and the popular STI turbo upgrade, making it a versatile choice for enthusiasts at various power levels. Best of all, no ECU tuning is required to enjoy these gains, though additional tuning can unlock even more potential. This kit enhances the Subaru WRX driving experience by improving throttle response, reducing turbo lag, and supporting future modifications.
