ABSTRACT:
An air intake manifold assembly (20) includes an intake manifold housing (22), made of a light weight material, and a pressure relief disk (38). The pressure relief disk (38) is mounted over a relief disk hole (26) in the housing (22). The pressure relief disk (38) engages the housing (22) to form a seal during normal engine operation. Should the manifold assembly (20) experience an induction backfire, pressure relief disk (38) includes a feature (52) that will rupture at a predetermined positive pressure, thus allowing for escape of the air while minimizing the potential for damage to the housing (22) and other components on the engine that are near to the intake manifold assembly (20).
