Abstract
The invention provides an apparatus and method to monitor air filter restriction within an air cleaner system of a motor vehicle. The invention uses a quick connect couplig to allow fluid communication between a restriction gauge and the air cleaner housing and also provides a means of attaching the restriction gauge or a remote tubing connector to the air cleaner housing. The quick connect coupling is located within an axial bore, generally within a conduit in the housing. A portion of the filtered air is drawn from the air cleaner housing through the quick connect coupling and into the restriction gauge, where the pressure is measured and the amount of air filter restriction is gauged.
