K&N High-Flow Original Lifetime Engine Air Filter: Increase Power: Compatible with 1999-2020 Cadillac/Chervolet/GMC: Escalade, Avalanche, Cheyenne, Silverado, Suburban, Tahoe, Sierra, Yukon, 33-2129

Got this for my Daughters rig. In my humble opinion these are the best air filters on the planet. I put them in all my vehicles. These will improve your HP, MPG. They are easy to install and clean. Improves air flow for improved performance. Excellent product, if your car doesn’t have a K&N air filter, Get one!

Exceeded expectations! Perfect fit and easy install. Averaged roughly 18mpg on a recent road trip for the first time ever. I attribute that mostly to the KN filter. Not much difference in power but thats ok, I drive a Chevy and don't need it 😉

Great filter! Just like I had hoped.

K&N in my personal opinion is the best choice for air filtration was exactly what I expected and would expect nothing less with their quality

We had over 20,000 miles on our 2015 Silverado crew cab 5.3L 4x4 truck when I installed it. I changed out the factory oil at 7700 miles, as per oil change monitor. Switched it to full synthetic, Castol Syntec 5/30, with Dexos, and change it at 4,000-4,200 miles,(ignore the monitor and reset it) and only using an A/C Delco oil filter. We drive long trips, 650 miles one way, back home, many times, so we got a good feel about the fuel mileage with the stock air filter and stock air box, and NOT EVER using cruise control. It will average 17.4 city and 27.8 hwy (@ 80mph) with the ethanol blend fuel (SUCKS) with the best fuel mileage so far, has been 30.7 mpg (+75 mph), running straight gas, no ethanol. This engine in not an E85 engine, and I think the ECM fuel table is set a little better because its not an E85 engine. We have put another 3,000 since installing this air filter, driving short trips on the weekends, and it has increased fuel mileage about 1.6 city and 3.3 miles per gallon hwy. In 2 weeks, we shall see what the change is on a long 785 mile one way trip across Montana. Well, the best mileage to date with straight gas is 34.7 mpg. Our G.M. dealer took a picture of the MPG mileage monitor, and asked how we managed that kind of mileage. I told him, straight gas, and I dont use cruise control. 2 reasons, 1) I can see a hill or raise in the roadway, and I can accelerate just a little, were the computor will notice a load, and then accelerate, using fuel, 2) I like to have my foot on the accelerator pedal, because you dont know what may happen in a split second, and have managed to stay out of trouble doing it this way.

It fit my truck great 👍 and it runs a lot better

this is perfect no more need to replace the filter. just wash it let it dry then give it a small amount of filter oil and then you are all set

Great!
