Keeping your engine breathing clean air is crucial, and this 2-pack of A-Premium air filters makes maintenance easy and affordable. These are direct replacements for the Buick LaCrosse 2018-2019 with the 2.5L engine, and the Chevy Malibu from 2016-2022 with 1.5L and 1.8L engines. The fine filtration media catches all the nasty dust, pollen, and debris without restricting airflow - which means better engine performance and fuel efficiency. At 13.74 inches long and 9.09 inches wide with that irregular shape, it fits perfectly in the factory location. Since you get two filters, you can install one now and have a spare ready for next time. Most manufacturers recommend changing air filters every 12 months or 12,000 miles, but if you drive in dusty conditions, you might want to do it more often. Installation is usually super simple - just pop the old one out and slide this one in. Way cheaper than dealership prices, and your engine will thank you!
