Perrin Front Mount Intercooler Boost Tube Kit Black 2022-2024 WRX | 2.25”-2.75” Diameter | Performance Boost Tubes
Overview
The Perrin Front Mount Intercooler Boost Tube Kit is a precision-engineered upgrade designed specifically for the 2022-2024 Subaru WRX. This kit replaces the restrictive OEM boost tubes with a larger diameter, mandrel-bent aluminum tubing system that optimizes airflow between the turbocharger, intercooler, and throttle body. It is ideal for Subaru enthusiasts seeking to improve charge air efficiency, enhance throttle response, and unlock additional power potential without sacrificing reliability or fitment.
Built with CNC mandrel bending and finished in durable black powder coat, these boost tubes feature a stepped diameter design that transitions from 2.25 inches at the turbo outlet to 2.75 inches near the intercooler and throttle body. This thoughtful engineering reduces pressure drop and turbulence, allowing the turbo to operate more efficiently. The kit includes CNC-machined direct-mount brackets made from lightweight aluminum, ensuring a secure, rattle-free installation that maintains OEM-level rigidity and fitment.
For Subaru WRX owners, this boost tube kit offers real-world benefits such as improved throttle response and dyno-proven wheel horsepower gains of 10 to 20+ depending on supporting modifications and tuning. The design maintains clearance around OEM components for straightforward installation and does not require an ECU tune to run safely, though tuning is recommended to maximize power gains. This makes it a practical and effective upgrade for those looking to enhance their turbo system’s efficiency while preserving factory reliability.
