The Speedmaster MID-AIR is a midrise aluminum intake manifold engineered for Chrysler small-block 318, 340, and 360 engines. Constructed from lightweight aluminum and finished in polished form, this manifold combines durability with a clean, professional appearance suitable for show vehicles and performance builds alike.
Designed as a direct bolt-on replacement, the MID-AIR manifold improves intake air distribution and flow characteristics compared to stock alternatives.
