Let your engine breathe clean air. ACDelco Engine Air Filters use world-class filter element technology to block 99 percent of airborne dust and dirt — including particles as small as a grain of salt — that can harm your engine. ACDelco Air Filters are available in panel and round styles to fit most vehicles, and they offer other benefits:
- Excellent filter capacity, enhanced efficiency, consistent flow management, and high durability that make our filters some of the market's best performers.
- The ability to trap microscopic dirt that can damage cylinder walls, pistons and piston rings.
- Tight seals that prevent unfiltered air from entering your engine.
- Sizes to fit virtually every car, light truck and sport utility vehicle on the road today.
Round-style filters also feature:
- A fine mesh screen to reduce the risk of fire caused by engine backfire.
- Heat-resistant plastic on the top and bottom with special sealing beads that provide a protective seal against automotive operating environments.
- A radial seal for easy installation on late model vehicles.
