This kit replaces restrictive OEM boost tubes with smooth, mandrel-bent aluminum tubing that improves charge air efficiency and supports higher boost levels. It’s ideal for STI owners looking to enhance power delivery and throttle response without the need for extensive modifications or tuning.\u003c\/p\u003e\n\u003cp\u003eCrafted with a focus on durability and performance, Perrin’s boost tubes feature a stepped diameter design—2.25 inches from the turbo outlet expanding to 2.75 inches near the intercooler and throttle body. This sizing maximizes airflow while maintaining a compact and efficient routing path that avoids interference with OEM components. The tubes are CNC mandrel bent for smooth internal surfaces, powder coated black for corrosion resistance, and equipped with oversized, beaded ends to ensure secure hose connections at any boost pressure.\u003c\/p\u003e\n\u003cp\u003eBeyond the boost tubes themselves, this kit includes a powder-coated coolant overflow tank that improves clearance for the new routing, as well as a robust steel intercooler support beam designed to withstand impacts better than the OEM aluminum bumper beam. The result is a reliable, bolt-on solution that delivers proven gains of 10-20+ wheel horsepower without requiring ECU tuning, making it a practical upgrade for Subaru WRX STI enthusiasts seeking both performance and reliability.\u003c\/p\u003e\n\u003ch4\u003eFeatures \u0026amp; Specifications\u003c\/h4\u003e\n\u003cp\u003eThis Perrin Front Mount Intercooler Boost Tube Kit is engineered specifically for the 2008-2014 Subaru WRX STI and features stepped boost tube diameters from 2.25” to 2.75”.
