The AEM short ram intake for the Mazdaspeed Miata (2004 1.8L) replaces the restrictive factory airbox with mandrel‑bent aluminum tubing and an oversized AEM Dryflow oil‑free synthetic filter to improve horsepower and torque while changing engine induction sound. The filter is protected by a heat shield to reduce hot intake air and is washable for long service life. The kit retains factory emissions connections and includes a high‑flow charge pipe.
