Fitment Information:
This charge pipe is specifically designed for 2022 - 2025 Subaru WRX models.
Features:
Upgrade your Subaru WRX with the PERRIN Charge Pipe! Say goodbye to the restrictive OEM plastic charge pipe. This high - performance pipe boosts horsepower and improves boost response. The OEM pipe on the WRX engine has a narrow design in some parts and pleats that disrupt airflow. In contrast, the PERRIN Charge Pipe has a super - smooth interior, consistent radii, and gentle bends. This design ensures efficient air delivery, resulting in increased power and better boost response. It's powder - coated for protection against the elements and adds a stylish look under your hood.
The PERRIN Charge Pipe comes with all the necessary connectors for easy installation on a stock system. The CNC machined turbo flange adapter uses the same design as the OEM flange on the turbo side and the OEM o - ring, guaranteeing a perfect fit and no leaks. The silicone connectors are multi - layered and reinforced for long - lasting durability and weather resistance.

Using your PERRIN Charge Pipe is straightforward. First, gather all the components included in the package, which are the charge pipe, turbo adapter flange, couplers, hose clamps, and the installation instructions. Make sure to follow the steps in the installation guide carefully. The pipe is designed to fit right onto your stock system, so no complex modifications are needed. And don't worry about tuning; it's not required. When it comes to maintenance, the powder - coated finish protects the pipe from the elements, but it's still a good idea to clean it regularly with a mild automotive cleaner. Check the silicone connectors and hose clamps from time to time to make sure they're in good condition. If you notice any signs of wear or damage, contact the manufacturer, as your charge pipe comes with a 5 - year warranty.
