PERRIN 2022 + Subaru WRX Front Mount Intercooler Boost Tube Kit - Red

PSP-ITR-441-3RD

The Perrin Front Mount Intercooler Boost Tube Kit is designed specifically for the 2022-2026 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 that features a stepped diameter design—from 2.25 inches at the turbo outlet expanding to 2.75 inches near the intercooler and throttle body. It’s engineered for Subaru enthusiasts seeking improved boost response, increased power potential, and reliable sealing at higher boost levels without the need for immediate tuning.

Perrin’s approach focuses on smooth, efficient airflow and durable construction. The tubes are routed to follow the shortest, most direct path while maintaining clearance around OEM components, simplifying installation and reducing pressure drop. The boost tubes are finished in a vibrant red powder coat that resists corrosion and maintains a clean, performance-oriented look. CNC-machined direct-mount brackets provide solid intercooler support with minimal flex, enhancing the overall system rigidity and longevity.

Real-world benefits include a proven gain of 10 to 20+ wheel horsepower by improving charge air cooling and reducing airflow restrictions. The design ensures no ECU recalibration is required to safely enjoy these gains, although additional tuning can unlock even more power. This kit is an ideal upgrade for WRX owners looking to maximize their vehicle’s forced induction efficiency while maintaining OEM-level fitment and reliability.
