AMS Performance Charge Pipe - Fits 2019-2025 Subaru Ascent
The AMS Performance 2019-2025 Subaru Ascent Charge Pipe is designed to maximize airflow and horsepower by replacing the restrictive OEM plastic piping with a full 2.5” high-flow charge air pathway, reducing restriction by 43% and increasing airflow by 25%. Precision-engineered with CNC-machined 6061 T6 billet aluminum and an optimized cast intercooler inlet bell mouth, the AMS Charge Pipe enhances throttle response and efficiency while providing increased durability over stock. Featuring a TMIC connection flange that has been enlarged by 13% for improved airflow, an AMS QuickClamp™ system for a secure, hassle-free installation, and OEM-style fitment for seamless integration, this charge pipe ensures both reliability and performance. Unlike the OEM plastic charge pipe that can deteriorate over time or crack under high boost, the AMS Charge Pipe is built to withstand extreme conditions, making it an essential upgrade for enthusiasts pushing their WRX to the next level. Whether you’re looking to improve drivability, increase reliability, or maximize your vehicle’s power potential, the AMS Charge Pipe delivers the results you need with race-proven engineering and superior craftsmanship.

OEM TMIC Fitment option includes an adapter to reduce the size of the inlet back to OEM. This improves airflow as it enters the smaller OEM TMIC inlet port.
AMS or Aftermarket TMIC Fitment option does not include an adapter. While we cannot guarantee fitment for all brands of aftermarket TMIC, the most popular options should be compatible.
