Perrin Front Mount Intercooler w/ Boost Tube Piping Kit 2015-2021 WRX | 906.5 cu-in Core | High-Flow FMIC Kit
Overview
The Perrin Front Mount Intercooler w/ Boost Tube Piping Kit is designed to replace the factory top mount intercooler on 2015-2021 Subaru WRX models, delivering significant improvements in cooling efficiency and power output. This kit is ideal for WRX owners looking to reduce intake charge temperatures, increase horsepower and torque, and add a more aggressive appearance to their turbocharged setup. By relocating the intercooler to the front of the vehicle, the Perrin FMIC maximizes airflow and thermal dissipation, addressing the common heat soak issues associated with the OEM top mount design.
Engineered with a focus on durability and performance, the Perrin FMIC features a large 3/8” bar and plate core that outperforms the factory tube and fin style intercooler. This core design not only improves cooling capacity but also enhances strength to withstand road debris and impacts. The kit includes CNC mandrel bent aluminum boost tubes with a powder-coated finish, ensuring smooth airflow and long-lasting corrosion resistance. Perrin’s attention to detail extends to the included aluminum coolant overflow and washer fluid tanks, which provide additional clearance for a clean, OEM+ installation.
Real-world testing demonstrates the effectiveness of this upgrade, with dyno results showing gains of 10-18 wheel horsepower and 10-15 ft-lbs of torque over the stock intercooler. Intake charge temperatures dropped by approximately 40°F, reducing heat soak and improving consistent power delivery during spirited driving or track use. For Subaru WRX enthusiasts, this front mount intercooler kit offers a practical and reliable way to unlock more performance while maintaining daily drivability and factory-like fitment.
