Product Description
The AMS Performance AMS.50.08.0003‑1 Airbox & Duct Kit is a performance support component engineered for the 2022–2025 Subaru WRX’s upgraded intake system. This kit includes an enlarged intake airbox and corresponding duct that feed cold air directly from the grille area into the intake filter, helping reduce intake air temperatures and maximize the efficiency of an aftermarket intake setup. Compared to the OEM duct design, the AMS airbox and duct feature a significantly larger overall connection size — over 149 % more — which enhances the ram‑air effect and allows cooler, denser air to reach the intake more effectively.
This kit is intended to be used with AMS high‑flow intake systems (such as AMS.50.08.0001‑1 or AMS.50.08.0002‑1) and is not a standalone intake — it does not include the intake pipe or filter element. Installation is straightforward with supplied mounting hardware using existing OEM locations, and the enlarged duct helps ensure that your engine breathes the coolest air possible for improved performance potential, sharper throttle response, and reduced heat soak during spirited driving.
