Intake Manifold Gasket For 02-06 Nissan Altima Sentra X-Trail 2.5L DOHC QR25DE. The intake manifold is an aluminum, steel or plastic cover that sits on top of the engine. It is attached to the top of the engine by an intake manifold gasket that is made of plastic and rubber. The intake manifold directs the air-fuel mixture in the engine to the corresponding cylinder where it is burned to produce power. The coolant flows through the intake manifold to the cylinder heads to reduce engine temperature. Expansion, contraction, and heat from the engine cause the gasket to fail. This will cause coolant passing through the intake manifold to leak. A leaky manifold gasket can also result in air being sucked through the leaky gasket, resulting in a vacuum leak and poor engine performance. Be sure to have your intake manifold gasket with aftermarket replacement intake manifold gasket as soon as it starts to give you trouble.
