Quality Product, Great Investment
Size: 1 Count (Pack of 1)
Installation was a bit of a hassle, but that has more to do with my skills than the product. Product seems to be of great quality. The stickers included to warn mechanics that the filter is not disposable is a blessing!

Just as excellent as all other K&N products I've used
Size: 1 Count (Pack of 1)
Great fit, and lot more more robust in build than the OEM filter it replaces. I've replaced the factory cabin air filters in at least 3 vehicles with these, when the time came to replace. Side note: This one went into a 2020 Lincoln Aviator and --consistent with my experience with previous Lincoln models -- the retaining tabs on the filter housing door snapped off when I was trying to remove it. Nothing to do with the K&N filter, but I just don't understand why Lincoln can't design a better housing door mechanism.
