This kit replaces restrictive OEM boost tubes with smooth, mandrel-bent aluminum piping that enhances boost response and reduces pressure drop. It’s ideal for Subaru enthusiasts looking to improve charge air cooling efficiency and unlock additional power potential without compromising reliability or fitment.\u003c\/p\u003e\n\u003cp\u003eEngineered with precision CNC mandrel bending, Perrin’s boost tubes feature a diameter progression from 2.25 inches at the turbo outlet to 2.75 inches near the throttle body. This design ensures a smooth, unrestricted airflow path while maintaining clearance around OEM components for a clean installation. The tubes are finished with a durable black powder coat that resists corrosion and maintains an OEM+ appearance under the hood.\u003c\/p\u003e\n\u003cp\u003eIncluded with the boost tubes are direct-mount intercooler brackets, a high-capacity 6061 aluminum washer fluid tank, and a textured powder-coated coolant overflow tank. These components facilitate proper routing and clearance, contributing to the overall performance gains. Dyno testing confirms a gain of 10 to 20+ wheel horsepower with no ECU tuning required, making this kit a practical upgrade for WRX owners seeking reliable power improvements and enhanced throttle response.\u003c\/p\u003e\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.
