Dual-Plane Air-Gap Aluminum Intake Manifold

Upgrade your Small Block Chevy with the Top Street Performance Satin Aluminum Dual Plane Air Gap Intake Manifold. Designed specifically for carbureted Chevy Small Block V8 engines, this manifold enhances airflow efficiency and throttle response, making it suitable for street performance, street/strip, muscle car, and restoration applications. The key feature is its advanced air-gap design, which creates an open area beneath the plenum. This design effectively isolates the intake runners from engine heat, ensuring the incoming air/fuel mixture remains cooler. Cooler charge temperatures lead to improved combustion efficiency, increased torque, and stronger overall power across the RPM range. This makes it a significant upgrade for enthusiasts seeking better performance from their Chevy 350, SBC 350, Chevy 400, or other small block Chevy engines. Optimized for a 1,500 to 6,500 RPM operating range, this dual-plane intake manifold balances excellent street manners with robust mid-range and upper-RPM performance. The dual-plane configuration ensures responsive throttle input and strong drivability, while the lightweight aluminum construction contributes to a cleaner engine bay appearance and reduced overall weight. The satin finish provides a high-performance aesthetic. This intake manifold is not compatible with spread bore carburetors (unless an adapter is used) and is not designed for LT1, LS, or other non-SBC engine platforms. Installation components, such as gaskets, are sold separately. It is crucial to verify carburetor, fuel system, linkage, and hood clearance before installation, as these factors can vary by vehicle.
