This is a direct replacement air filter for the Honda Insight with the 1.5L L4 gasoline engine, for model years 2019, 2020, 2021, and 2022. It's a standard maintenance part that helps keep dirt and debris out of your engine. Replacing a dirty air filter can help with fuel efficiency and engine performance. It's compatible with all trim levels of the Insight for those years. It replaces a bunch of OEM part numbers like CP182, CF11182, 80292-TF0-G01, and also fits many common aftermarket numbers like 042-1927, AF5279, etc. (a long list is in the description). General recommendation is to change your engine air filter every 12 months or every 12,000 to 15,000 miles, but check your owner's manual for your specific schedule. Before buying, it's always a good idea to double-check compatibility using Amazon's 'My Garage' tool by entering your vehicle's year, make, and model to be 100% sure. Installation is usually pretty straightforward if you're a bit handy, or any mechanic can do it in minutes.
