What is an engine air filter?

Engine air filters prevent contaminants like dust and dirt from entering your car's engine.

Why do I need to replace my engine air filter?

The combustion process requires oxygen, and an engine filter prevents particles in the air from getting into your car's engine. Car engine air filters should be replaced several times throughout the lifespan of your vehicle to keep your engine running optimally. A clogged filter can prevent your engine from getting enough air to run properly and cause misfiring, odd sounds, or potent gas smells when starting your car.

How long do engine air filters last?

Engine air filter changes should occur every 12 months or every 12,000 miles. Replacing your engine air filter consistently can improve fuel economy and engine performance.

How do I know which engine filter I need?

We recommend checking your car's owner’s manual to confirm what auto engine air filter you need. You can also search your car's part number or make and model to find your engine air filter replacement.
