Dodge Stealth Intake Manifold Seal Gasket

They seal different joints. An intake manifold gasket seals a manifold connection; a cylinder head gasket seals the joint between the cylinder head and engine block. Identify the leaking joint before selecting the gasket.

An air leak at the intake can upset the expected air supply and contribute to a rough idle or hesitation. A vacuum hose, intake connection or manifold damage can create similar symptoms, so locating the leak matters more than the symptom alone.

Set contents vary. An upper-only set and a set listed for both upper and lower locations have different repair scopes. Check the itemized contents against the joints being opened and any other seals required for the engine.

Use sealant only where the gasket and engine service instructions specify it. For example, Fel-Pro directs certain molded intake gaskets to be installed clean and dry, while some repairs use sealant at particular joints. Do not assume that instruction applies unchanged to every gasket.

Some intake manifold joints include coolant passages, so a gasket at that location can be involved in a coolant leak. Other designs seal only air passages. The engine's layout and the actual leak location determine the repair.
