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 designed specifically for the 2015-2021 Subaru WRX to optimize airflow between the turbocharger, intercooler, and throttle body. This kit replaces restrictive OEM boost tubes with CNC mandrel bent aluminum tubing, featuring diameters sized from 2.25 inches at the turbo outlet to 2.75 inches near the intercooler and throttle body. It is ideal for WRX owners seeking improved boost response, increased airflow capacity, and a more aggressive engine bay appearance with its distinctive neon yellow powder coat finish.

Engineered with a focus on smooth, efficient routing, Perrin’s boost tubes utilize the shortest and most direct path to reduce pressure drop and turbulence. The oversized, beaded ends ensure secure hose connections at any boost level, preventing leaks and maintaining consistent performance. The kit also includes a high-capacity aluminum washer fluid tank and a powder-coated coolant overflow tank, both designed to provide additional clearance for the boost tubes while maintaining OEM+ quality and durability.

Real-world benefits include a proven increase of 10 to 20+ wheel horsepower without requiring ECU tuning, thanks to improved charge air cooling and reduced intake restrictions. The direct-mount intercooler brackets add rigidity and a clean, performance-focused look to the engine bay. This kit is a practical upgrade for WRX enthusiasts looking to enhance power delivery and engine efficiency while preserving reliability and ease of installation.
