AEM Cold Air Intake System 21-875DS for BMW Z4 (2019-2020) & Toyota Supra (2020-2024)

AEM 21-875DS Performance Cold Air Intake System

If you're looking to boost the performance of your 2019-2020 BMW Z4 or 2020-2024 Toyota Supra, the AEM 21-875DS Performance Cold Air Intake System is a must-have upgrade. This system replaces the restrictive factory air intake housing, allowing your engine to breathe freely and efficiently. Designed, tuned, and dyno-tested, it delivers an estimated horsepower gain of 8 HP and torque improvements, especially noticeable at 5000 RPM.

How It Works

Air enters through the factory fresh air inlets and flows through a high-performance replacement air duct into a roto-molded AEM air box. This air box houses an oversized AEM Dryflow synthetic washable air filter that is engineered for optimal airflow and filtration. The cone-shaped filter is made from oil-free synthetic material, allowing for up to 100,000 miles of use before needing a clean, depending on your driving conditions.
