Perrin Front Mount Intercooler Boost Tube Kit Neon Yellow 2015-2021 WRX | 2.25"-2.75" Diameter | Aluminum Boost Tubes
Overview
The Perrin Front Mount Intercooler Boost Tube Kit is a precision-engineered upgrade designed specifically for the 2015-2021 Subaru WRX. This kit replaces the restrictive OEM boost tubes with smooth, mandrel-bent aluminum tubing that optimizes airflow between the turbocharger, intercooler, and throttle body. Featuring a diameter progression from 2.25 inches at the turbo outlet to 2.75 inches near the intercooler and throttle body, it enhances boost response and airflow capacity while adding a striking neon yellow finish to the engine bay. This product is ideal for WRX owners seeking a reliable, performance-oriented upgrade that improves power delivery without compromising OEM quality.
Engineered with a focus on efficient routing and durability, Perrin’s boost tubes utilize the shortest and most direct path to minimize pressure drop and turbulence. The CNC mandrel-bent aluminum construction ensures consistent diameter and smooth bends, while the oversized, beaded ends provide secure hose connections at all boost levels. Included in the kit are a high-capacity aluminum washer fluid tank and a powder-coated coolant overflow tank, both designed to maintain proper clearance and OEM+ integration. The direct-mount intercooler brackets add rigidity and a clean, professional look to the engine bay.
In real-world use, this boost tube kit delivers proven gains of 10 to 20+ wheel horsepower without requiring ECU tuning, thanks to improved charge air cooling and reduced intake restrictions. This makes it a practical and effective upgrade for Subaru WRX enthusiasts looking to enhance power delivery, throttle response, and engine efficiency while maintaining reliability and ease of installation.
