DIY - Save $$
Size: 1 Count (Pack of 1)
Comparable item dealers provide, but if you can DIY, you’ll save $40-50 bucks installation. Helpful hint, before installing, take a market and put the date and mileage of the end of the filter. Unless you drive a lot, the filters generally last a year.

Got it when they couldn't
In stock and fast shipping was the selling point. My local auto parts stores didn't have this in stock anywhere. I got it in two days and cheaper than they could get it to me. Fits great and works like it should. I'm on top of my maintenance for all my vehicles, so it will get changed on time. Life span should not be an issue.
