By replacing the restrictive OEM boost tubes with smooth, mandrel-bent aluminum tubing, this kit enhances charge air efficiency and supports higher boost levels. It is tailored for STI owners aiming to improve power delivery and throttle response without requiring extensive modifications or mandatory tuning.\u003c\/p\u003e\n\u003cp\u003eEngineered with a focus on durability and performance, Perrin’s boost tubes feature a stepped diameter design that starts at 2.25 inches from the turbo outlet and expands to 2.75 inches near the intercooler and throttle body. This sizing strategy maximizes airflow while maintaining a compact routing that avoids interference with OEM components. The tubes are CNC mandrel bent to ensure smooth internal surfaces, powder coated black for corrosion resistance, and equipped with oversized, beaded ends to guarantee secure hose connections at any boost pressure.\u003c\/p\u003e\n\u003cp\u003eBeyond the boost tubes, the kit includes a powder-coated coolant overflow tank to improve clearance for the new routing and a robust steel intercooler support beam designed to withstand impacts better than the OEM aluminum bumper beam. This combination delivers a reliable, bolt-on solution that yields proven gains of 10-20+ wheel horsepower without requiring ECU tuning, making it a practical and effective upgrade for Subaru WRX STI enthusiasts focused on both performance and reliability.\u003c\/p\u003e\n\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”.
