The intake plenum on a V-6 or V-8 is bolted to the top of the intake manifold. It has the throttle body bolted to it. The throttle body houses the throttle plate and is located at the end of the tube that starts at the air filter housing. Sometimes the intake manifold on a 4 cylinder is referred to as a plenum. It works the same way and is found in the same manner. Look for the air filter housing, then follow the hose past the throttle body to the intake or plenum.
