Aluminum Mandrel-Bent Charge Pipe

The PERRIN Charge Pipe directly replaces the restrictive OEM plastic charge pipe in the 2022-2026 Subaru WRX, addressing the factory component's tendency to narrow and feature pleats that impede airflow. Constructed from precision CNC mandrel-bent aluminum tubing, this charge pipe ensures consistent and perfect fitting parts. Its design promotes a perfectly smooth interior with gradual bends, leading to more efficient air delivery, ultimately aiming to increase horsepower and improve boost response. The turbo flange adapter is CNC-machined to precisely match the OEM design, utilizing the factory O-ring for a leak-free installation. The silicone connectors are reinforced and multi-layered for enhanced durability and weather resistance. This charge pipe is designed and tested to work safely without ECU recalibration or a tune, but additional power gains can be achieved with proper ECU tuning. It is important to confirm that any tune or recalibration is specific to all modifications added to the vehicle. The charge pipe is finished with a durable powder coat, available in textured red and black, or glossy neon yellow and pink, to complement the engine bay. All engine and exhaust components, including charge pipes, are designed and intended for off-road applications only and may be subject to federal and state laws prohibiting their use on public highways. Users are responsible for ensuring compliance with local and federal laws prior to installation. Installation of performance products may also void vehicle warranty coverage.
