The Spectre dual plenum is a polished cast-aluminum intake piece with two 4-inch inlets set 90 degrees apart and designed to fit carburetors and TBI throttle bodies with a 5-1/8-inch neck. It measures about 3.5 inches tall and 8 inches from the air cleaner stud to each inlet, allowing connection to two 4-inch intake tubes and accessories to support split intake routing and custom filter placement for cleaner airflow paths.
