K&N surprise !
I needed a new air filter for my 2012 QX56, with 5.6liter V8 that eats escalades, LOL .I could tell that fuel mileage had dropped just a bit over last spring. So I opened the filter case and yeah it was quite dirty. So I was looking at the Wix air filter listed here on amazon for a QX, but it doesn't have that 'notch' in the corner of the filter so I was afraid to order it. Then I saw the good price here on the K&N filter. I had not tried a K&N air filter before, so why not.It was here in three days and It fit perfectly. The K&N has a larger filter area where the stock filter was plastic for a good two inches of filter area.Immediate difference. The fuel mileage is up to 19 mpg, consistently! I didn't buy the QX for fuel mileage, mostly cause it is built like a tank. That K&N will let the 5.6 'sing' a little too. It sounds good on acceleration,where it was quite muffled before. I like the idea that the engine is getting more air, and the boost in fuel mileage is a bonus, if I can keep my foot out of the accelerator. It is a well built made in USA air filter. I am glad I tried it.I think you will notice a difference for the better too! Thanks K&N.

Awesome Product, but beware when installing.
I love K/N filters in general. Don’t have to twist my arm to invest in them. The only negative to this particular filter (33-2456) for my wife’s 2019 Armada was that I had to position it in the top half of the air filter box and then clamp it down. Fits like a glove! So, beware if you own this particular year/model.

Frustrating first try to install the filter
Just installed the air filter after seeing K&N online that for my vehicle you needed to install it by holding it in the top lid. I had tried to get it to fit by putting in the bottom first which would not work. I did not receive any instructions with the filter. Little frustrating but it went right in once I did that. This was different from one that came with the car.
