Engineered for maximum airflow and race-winning performance, the AFR BBC Magnum Rectangle Port Single Plane Intake is purpose-built for serious big block Chevrolet combinations. Designed specifically to complement AFR’s 357cc–385cc rectangle port cylinder heads, this intake is optimized for 540+ cubic inch engines operating in high-RPM environments up to 8000 RPM.
 
Featuring a large, race-proven plenum and precision-tuned runner geometry, the Magnum intake delivers exceptional cylinder-to-cylinder distribution and high-RPM efficiency. The 4500 Dominator flange provides the airflow capacity required for aggressive camshaft profiles and high-demand fuel systems, making it an ideal choice for naturally aspirated race engines as well as power-adder applications.
 
Cast from premium aluminum and engineered in-house by AFR, this intake manifold is built to handle the demands of drag racing, competition engines, and max-effort big block builds where peak horsepower and consistency are critical.
 
When paired with AFR’s high-flow rectangle port heads, the Magnum intake completes a fully optimized top-end package designed to perform at the highest level.
