Nissan Intake Manifold Gasket

Description

What happens if you don’t replace intake manifold gasket?
A damaged intake manifold gasket often has cracks and gaps in its foundation. With cracks and gaps present, air or vacuum leaks can occur. The worst part is that these leaks can affect the air-to-fuel ratio inside the engine. As a result, the engine may vibrate and revolutions per minute (RPM) may become unstable.
