Perrin Front Mount Intercooler Boost Tube Kit - Black - 2022+ WRX

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 engineered specifically for the 2022-2024 Subaru WRX to optimize airflow between the turbocharger, intercooler, and throttle body. Designed for enthusiasts looking to improve their vehicle’s charge air efficiency, this kit replaces restrictive OEM boost tubes with larger diameter, smooth mandrel-bent aluminum tubing. It’s ideal for those aiming to maximize power gains without compromising reliability or fitment.

Built with precision CNC mandrel bending, the boost tubes feature a diameter progression from 2.25 inches at the turbo outlet to 2.75 inches near the intercooler and throttle body. This design reduces pressure drop and turbulence, allowing the turbo to breathe more freely. The tubes are finished with a durable black powder coat for corrosion resistance and a clean, OEM+ appearance. Included are CNC-machined direct-mount brackets made from lightweight aluminum, ensuring a secure, rattle-free installation with excellent rigidity.

Real-world benefits include improved throttle response and potential wheel horsepower gains of 10 to 20+ depending on supporting modifications and tuning. The smooth, short routing maintains clearance around OEM components, making installation straightforward. Importantly, this kit is designed to work safely without requiring an ECU tune, though additional gains are possible with proper calibration. For Subaru WRX owners, this boost tube kit is a practical upgrade that enhances the efficiency of the turbocharging system while maintaining factory-level reliability.
