    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.
