MAHLE MS15166X intake manifold gasket set for the 1975-1976 Ford F-150 5.9L / 6.4L and other vehicles seals the intake manifold joint so unmetered air stays out of the engine.
A leaking intake manifold gasket can show up as a rough idle, a hissing sound or a lean-running condition. Before you replace the set, rule out a cracked vacuum hose or a loose fitting, since either can leave you with the same hiss and rough idle.
The 1975-1976 Ford F-150 5.9L / 6.4L takes one set. As a gasket set, it also fits the 1965-1976 Ford F-250 5.8L / 5.9L / 6.4L and the 1967-1970 Ford Mustang 7.0L. If your car isn't named here, look up your year and engine in the "Vehicles it fits" section, because this set covers a wide range of other vehicles.
