Perrin Charge Pipe - Black - 22-23 WRX, 19-22 Ascent, 20-23 Legacy XT, 22-23 OB Wilderness, 20-23 OBXT

Replace the restrictive OEM plastic charge pipe to increase horsepower and boost response with the PERRIN Charge Pipe.

Features:

• No Tuning Required- Increase horsepower and torque without ECU recalibrate 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.
