2015-2021 Subaru WRX Black Charge Pipe by Perrin

Replace the restrictive OEM plastic charge pipe to increase horsepower and boost response with the PERRIN Charge Pipe for 2015-2021 WRX!

No Tuning Required - Increase horsepower and torque without ECU recalibration or tune! This part is designed and tested to work safely on your vehicle without any tuning required! However, more power can be gained with proper ECU tuning! Confirm any tune or recalibration you add is specific for ALL modifications added to the vehicle.

Better Airflow - The OEM charge pipe on the WRX engine is restrictive, narrows down in certain points, and has pleats that make for uneven airflow. The PERRIN Charge Pipe has a perfectly smooth interior, constant radii, and gradual bends, making for much more efficient air delivery. This all combines to increase horsepower and improve boost response.

Power - Add 8-10 WHP to your car! Actual horsepower values will vary depending on other installed hardware, tunes, and the overall condition of your vehicle.

Connectors and Compatibility - The PERRIN Charge Pipe comes with all the necessary connectors to install onto a stock system for greater compatibility. The CNC-machined PERRIN turbo flange adapter uses the same design as the OEM flange on the turbo side of the charge pipe and uses the OEM O-ring for perfect fitment and no leaks, unlike off-the-shelf O-rings. The silicone connectors are reinforced and multi-layered for durability and weather resistance.

Construction - PERRIN Charge Pipes are constructed from aluminum tubing, which is precision CNC mandrel bent, for consistent and perfect fitting parts.
