2005 Nissan Altima - Plenum Gasket Set

Nissan Altima Plenum Gasket Set

The intake plenum is a chamber located between the throttle body and intake manifold on your Nissan Altima. It splits incoming air evenly between each cylinder as it enters the engine. The air in the plenum passes through the air filter and MAF sensor, which calculates how much air is delivered. When a plenum gasket fails, the engine may bring in unfiltered air through a vacuum leak. This can cause dust and debris to enter the engine, which can block valves or corrode cylinders over time. Bypassing the MAF sensor on your Altima can also cause the vehicle to pull more air in than needed through leaks in the plenum gasket and run lean. This can cause stalling, rough idle, and poor acceleration, among other performance problems. If you have noticed these problems, then you should inspect the plenum gaskets and replace these parts if there are signs of a vacuum leak around the plenum.
