The Turblown 20B 3-Rotor Lower Intake Manifold is designed to improve airflow balance and performance on high-power Mazda 20B builds. Its equal-length tapered runners reduce the uneven airflow found in the OEM manifold, improving throttle response and helping achieve more consistent airflow between all three rotors.
The manifold is 40mm lower than OEM, features 8% larger secondary runners, and includes a dedicated -8AN ORB billet fuel rail. Available for Side Port or Semi Peripheral Port engines.
