Did not fit right out of box. Had to trim with scissors.
Size: 1 Count (Pack of 1)
Good value. A little flimsy but pretty much what I expected. My only real complaint is that out of the box it did not drop right in to my Honda Odyssey. I had to trim the tabs on one end with scissors for it to fit in to the filter housing.

Good Quality, Easy to Install
Size: 1 Count (Pack of 1)
Good product, easy to install, but make sure to locate the direction arrow for proper installation. This one didn't have a very clear arrow but figured it out quickly and the install was done in seconds. I recommend this product.

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.
