It replaces the restrictive OEM boost tubes with smooth, mandrel-bent aluminum piping that optimizes airflow from the turbocharger through the intercooler to the throttle body. This kit is ideal for Subaru enthusiasts aiming to improve boost response, reduce pressure drop, and unlock additional power potential while maintaining reliable fitment and durability.\u003c\/p\u003e\n\u003cp\u003eCrafted with CNC mandrel bending, the boost tubes feature a stepped diameter design, starting at 2.25 inches at the turbo outlet and expanding to 2.75 inches near the throttle body. This gradual increase ensures a smooth, unrestricted airflow path that enhances charge air cooling efficiency without interfering with surrounding OEM components. The black powder coat finish not only protects against corrosion but also provides an OEM+ aesthetic that blends seamlessly under the hood.\u003c\/p\u003e\n\u003cp\u003eBeyond the boost tubes themselves, this kit includes direct-mount intercooler brackets, a high-capacity 6061 aluminum washer fluid tank, and a textured powder-coated coolant overflow tank to facilitate proper routing and clearance. Dyno testing confirms gains of 10 to 20+ wheel horsepower without requiring ECU tuning, making this a practical and effective upgrade for WRX owners seeking improved throttle response and reliable power gains.\u003c\/p\u003e\n\n\u003ch4\u003eFeatures \u0026amp; Specifications\u003c\/h4\u003e\n\u003cp\u003eThis Perrin Front Mount Intercooler Boost Tube Kit is engineered for 2015-2021 Subaru WRX models and features a stepped diameter design from 2.25” to 2.75” for optimized airflow.
