Air Filters

Replace Clogged Air Filters

Most drivers know the basic functions of their vehicle's systems, but fewer understand the signs of gradual wear and when replacement becomes necessary. Air filters are the pleated paper or synthetic elements housed in a plastic box that remove dirt and debris from air entering the engine. These filters prevent contaminants from reaching the combustion chambers where they would cause cylinder wear and damage. Clean air filters ensure proper air flow for efficient combustion and maximum power output. We stock genuine Nissan air filters manufactured with correct dimensions and filtration ratings for your engine's intake system.

How Air Filters Protect Your Engine

Air filters trap particles as air flows through pleated media on its way to the engine. The large surface area created by pleating allows high flow rates while maintaining effective filtration. Filter media captures dust, pollen, insects, and other airborne contaminants before they enter the intake manifold. The housing seals around filter edges to prevent unfiltered air from bypassing the element. Your Sentra and Murano both require air filters sized to match their engine displacement and airflow requirements. These components work with the air intake system to deliver clean air for combustion. Genuine Nissan air filters use electrostatically charged media that captures smaller particles without restricting flow.

Why Air Filters Get Dirty

Air filters accumulate contaminants from normal use as thousands of cubic feet of air pass through daily. Dusty driving conditions or unpaved roads accelerate dirt accumulation. Leaves, insects, and debris enter the air intake system during certain seasons. Filter media deteriorates from moisture exposure and temperature cycling. Aftermarket filters often use single-layer media that clogs quickly and may not seal properly in the housing. Generic filters may have incorrect dimensions that allow gaps for unfiltered air entry.

When Air Filters Need Replacement

Replace air filters when visual inspection shows heavy dirt accumulation or media discoloration. Reduced acceleration or engine power indicates restricted airflow from a clogged filter. Increased fuel consumption can result from improper air-fuel mixture due to insufficient air supply. If the check engine light illuminates with lean mixture codes, air filter restriction may be the cause. Most air filters require replacement every 15,000 to 30,000 miles depending on driving environment. We stock all the parts you need for your car repair, and can ship them to your garage fast.
