Perfect
Great quality and perfect fit. Don’t fall for the ones that cost more and say that they are super duper filtering marvels. They work the same way and you have to replace them eventually anyway.

Perfectly Fine and Inexpensive
This off-brand filter was $10 cheaper than the local auto store, nearly $20 cheaper than the dealership, and meets the original OEM requirements. My husband is an ASE certified master technician and does all of our car maintenance and repair work himself and purchasing this filter rather than getting the filter from the dealership or the local auto store saved us a good bit of money and it is the same quality. Just make sure that the OEM number is correct for your vehicle and you have nothing to worry about.
