This kit replaces the restrictive OEM boost tubes with larger diameter, smooth mandrel-bent aluminum tubes that optimize airflow from the turbocharger to the intercooler and throttle body. It’s ideal for STI owners looking to reduce pressure drop, improve boost response, and support higher power levels without compromising reliability.\u003c\/p\u003e\n\u003cp\u003eEngineered with precision CNC mandrel bending, the boost tubes maintain a smooth, short routing path that minimizes turbulence and maximizes airflow efficiency. The oversized, beaded ends ensure a secure, airtight seal with OEM hoses at any boost level. Finished in a durable neon yellow powder coat, these tubes not only resist corrosion but also add a distinctive visual upgrade under the hood. The kit also includes custom CNC-machined aluminum intercooler brackets, a high-capacity washer fluid tank, and a textured powder-coated coolant overflow tank to facilitate clean and efficient installation.\u003c\/p\u003e\n\u003cp\u003eReal-world benefits include a proven gain of 10 to 20+ wheel horsepower across various power levels, achieved through improved charge air cooling and reduced intake restriction. The design requires no ECU tuning to safely increase power, making it a straightforward upgrade for STI enthusiasts. For those pursuing further modifications, the kit supports additional tuning to unlock even greater performance potential, all while maintaining OEM-level fitment and durability.\u003c\/p\u003e\n\u003ch4\u003eFeatures \u0026amp; Specifications\u003c\/h4\u003e\n\u003cp\u003eThis Perrin Front Mount Intercooler Boost Tube Kit is engineered for the 2015-2021 Subaru WRX STI and features boost tube diameters ranging from 2.25 inches at the turbo outlet to 2.75 inches near the throttle body.
