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.

The K&N High-Flow Original Engine Air Filter is fantastic! Installation was simple, and it fits perfectly. I’ve noticed a slight improvement in throttle response and overall engine performance, which is great. The filter feels very durable, and I love that it’s washable and reusable — a cost-effective choice in the long run. Definitely a high-quality product that I’d recommend to anyone looking to improve airflow and maintain engine efficiency.
