Air filters are great
Size: 10-24 4RUNNER, 10-23 GX460
I received when promised and it fit my automobile correctly, I get good gas mileage already so we will see if the gas mileage comes up. The quality was great always looking for high quality when changing the air filters and this item met that standard. Go ahead and buy it will meet you demands.

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.

Excellent Air filter - Easy installation.
Style: BE-743 1-Pack
Excellent AC and Heater Cabinet odor defense air filter. I noticed immediately the smell coming out of the vents was fresher and the musty smell that was coming from the vents was crisper and cleaner. Very easy installation that you can do yourself and don’t need to pay a shop to do. The price is one of the best online and coms in quickly. It’s very sturdy, filter quality is excellent and it definitely improves the air quality and flow in your car. Fits perfectly like any OEM filter, this is a great buy for the price of an installation that will take you Les then 10 minutes to do yourself.
