This kit replaces the restrictive OEM boost tubes with mandrel-bent aluminum tubing that increases diameter from 2.25 inches at the turbo outlet to 2.75 inches near the throttle body. It is ideal for STI owners aiming to improve intercooler efficiency, reduce pressure drop, and support higher power levels without sacrificing reliability or fitment.\u003c\/p\u003e\n\u003cp\u003eCrafted with smooth mandrel bends and oversized beaded ends, the boost tubes optimize airflow while maintaining secure hose connections at all boost pressures. The powder-coated red finish not only enhances durability but also adds a subtle visual upgrade under the hood. Included in the kit is a new coolant overflow tank and an intercooler support beam, both powder coated to ensure proper clearance and system integrity. Perrin’s commitment to quality materials and thoughtful design makes this kit a standout choice for Subaru enthusiasts focused on performance and reliability.\u003c\/p\u003e\n\u003cp\u003eBy improving charge air cooling and reducing pressure loss, this boost tube kit supports power gains of 10 to 20+ wheel horsepower across various tuning stages. Notably, it delivers these gains without requiring ECU recalibration, allowing for a straightforward bolt-on upgrade. For those pursuing further performance, additional gains are achievable with professional tuning tailored to the full vehicle setup. This combination of performance, fitment, and ease of installation makes the Perrin boost tube kit a practical and effective upgrade for WRX STI owners looking to enhance their turbo system’s efficiency.\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 2008-2014 Subaru WRX STI models and features smooth mandrel-bent aluminum tubing with diameters ranging from 2.25” to 2.75”.
