As someone with zero experience changing air filters, I was honestly surprised at how easy this was. The fit was perfect for my 2010 Honda Accord Sport, and both the cabin and engine air filters installed with no issues at all. It even came with clear, easy-to-follow instructions that made the whole process stress-free. Saved myself money from going to the dealership, and my car is running great. Definitely recommend for beginners wanting to do a simple DIY maintenance job.

Great value

Size: 18-26 Expedition, 15-26 F-150, 18-26 Navigator

The engine air filter fit perfect. The cabin air filter was a bit of a challenge fitting. seemed to be a bit larger but it went in and got the cap back on the box. For the price you cant beat it. Would buy again!

Great Filter Set for Allergy‑Sensitive Families and MPG‑Minded Drivers

Size: 21-25 TLX, 18-25 Odyssey

I bought this set because I prefer handling routine maintenance myself, especially cabin and engine air filters, rather than paying dealership prices for simple jobs. The package included one cabin air filter and one engine air filter, plus a full backup set for the next service interval. Both filters installed easily and fit the 2018 Honda Odyssey exactly as expected. No trimming, no forcing, and no alignment issues. The cabin filter seated cleanly in the glove‑box housing, and the engine filter dropped into the airbox without any airflow restriction or sealing gaps. This setup is ideal for Odyssey owners who want to maintain optimal cabin air quality—especially helpful for families with allergies—and for drivers looking to keep engine airflow unrestricted for the best possible MPG and throttle response. It may not be necessary for anyone who relies exclusively on dealership service or doesn’t perform their own maintenance. Overall, this is a straightforward, high‑value filter set that installs cleanly and supports both air quality and engine efficiency for DIY‑minded Odyssey owners.
