K&N NextGen Cold Air Intake System: High-Flow Cotton Filter: Compatible with 2014-2020 CADILLAC/CHEVRLOET/GMC Escalade; Silverado 1500; Suburban; Tahoe; Sierra 1500; Yukon; Yukon XL; 50-3082

Instructions are very straightforward had no issues following them or completing the job. Absolutely no guess work. Filter is definitely huge and open. Highest of quality which is to be expected from a company like K&N. 0-30mph is where I feel like there’s the most power increase. Can’t speak much for fuel efficiency or gas mileage yet. With a tune I’m sure you could get much more and expect much more from the product but no tune is required and that’s why I purchased it. As a bonus it works on the 5.3 engine but the provide a coupler for the 6.2 engine/throttle body so if you have the 6.2 drop this bad boy in or if you plan to upgrade your throttle body and intake manifold to the 6.2 or already have this would make for a great addition to your set up and you should see substantial power increase with a good tune and exhaust. So wether this is your first upgrade or an overdue upgrade longevity of the product should be of no concern to you.

I installed the NextGen model on my 2019 5.3L Tahoe Texas Edition SUV. Very disappointed with form and fit for this unit. It was very difficult to get the air box into position and required removal of a corner brace to do so. The remainder of the install was going as planned until it was time to connect the cold air pipe between the throttle body and the air box. It simply did not fit. It was about 1.5 inches too long. In order to make it work required trimming a little more than an inch of the pipe on the air box end. Luckily, it is made of plastic and there was enough smooth material left on the box end of the pipe to allow engagement of the band clamp. In the end the installation was successful but not pleasant. I could not find any reviews of the NextGen model air intake at all. Am I the first?

I splurged and purchased this for my birthday. Only came with 1 hose, 2 barbed fittings for the hose, and the red and orange clips for the filter came mismatched in length. Everything I’m reading online, videos, and even the instructional booklet that comes with this says those clips are supposed to be the same length. Can’t figure out a way to install them without cutting off a bit of the orange clip. Excess plastic in the female brass fittings that I needed to clean out. Lots of plastic shavings inside the intake tube that I needed to blow out with my air compressor. Just disappointed at the quality control on a $400 plus item. I was 90% done with the he install when I realized the second hose wasn’t included and had to completely reinstall my factory air intake in order to drive to the auto parts store to buy another PCV hose. I should have double checked before I got started with the install, that’s my fault for sure, but you just expect all key components to be included in the kit from a big name brand like K&N.

Received only 1 of 2 intake hoses? You pay over $400 dollars for some plastic, you’d expect to at least get all of the necessary equipment.

Great install very clean and simple VERY noticeable difference!
