An air cleaner is used to keep airborne dirt and dust out of the air flowing through the engine. Proper maintenance is vital, as a clogged element will restrict air flow and power, and allow excessive contamination of the oil with abrasives.
Maximas are equipped with a disposable, paper cartridge air filter element. The element should be checked at every tune-up or sooner if the vehicle is operated in a dusty area. Nissan does not recommend attempting to clean and reuse the element. The filter element should be replaced every 30,000 miles (48,000km).
