The Spectre SPE751 Plenum Kit is designed for classic muscle car applications requiring a compact, polished aluminum air intake solution. Its low-profile plenum fits carburetors and TBI throttle bodies with a 5-1/8-inch inlet, making it suitable for engine bays with limited hood clearance. The polished aluminum construction provides a clean appearance while supporting durable performance in demanding automotive environments.
The included aluminum intake tube has a 4-inch outside diameter and is designed with both 45-degree and 90-degree bends. The tube can be installed in either direction, giving you two positioning options for locating an air filter on the passenger side of the engine bay. This flexible configuration helps simplify installation and allows the intake routing to be adapted to the available space in your vehicle.
The Spectre SPE751 includes two worm-gear clamps and a coupler to help complete installation. Compatible associated products include Spectre heat shield SPE-8130, conical filters SPE-8131, SPE-8132, and SPE-8136, plus air filter duct hose adapter SPE-8147. Before closing the hood, verify adequate clearance between the carburetor or TBI neck and the underside of the hood. This product is not carburetor-approved and may require acknowledgment of applicable emissions or installation requirements.
