This satin-finished aluminum single plane intake manifold is built for GM LS Gen III / IV platforms and fits LS1, LS2, LS6 cathedral-port cylinder heads. Machined from cast aluminum, it offers strength, reduced weight, and resistance to warpage under heat. The single plane runner design is optimized for higher RPM performance and supports a 4150 square-bore throttle body or carburetor. Its low profile helps with hood clearance in many performance vehicles. Precision CNC ports and O-ring flange mounting ensure consistent airflow and reliable sealing. Ideal for engine builders, street performance enthusiasts, and racing hobbyists, this manifold is suited for builds aiming for high revs, cam upgrades, or forced induction setups. Whether you’re constructing a muscle car, restomod, or track machine, this single plane aluminum intake manifold delivers balanced power, durability, and compatibility for LS1/LS2/LS6 engines on the GM LS platform.
