K&NCold Air Intake System: High-Flow Air Filter, Increase Performance & Towing: Compatible with 2014-2020 Chevy/GMC/Cadillac Silverado 1500, Suburban, Tahoe, Sierra 1500, Yukon, Escalade, 63-3082

The unit wasn't difficult to install and the instructions were very helpful. Keep in mind that there are 2 fitment tubes for different engine sizes, so select the correct tube for the engine fit that you have.I have seen a gas mileage increase and the growl from the increased air flow sounds good. There is some power increase and the shifting points are smoother. It is a great value for money considering the performance increase.

Installation: Easy to install but for the emissions hoses I did upgrade to (2) brass 5/8" barb to 1/4" NPT and added my own (4) worm gear hose clamps (get the size that goes from 0.5" to 1.25"). Really a shame that K&N is too cheap to provide these. On the 6.2L the hose coupler to the throttle body seems too large but the clamps are able to secure it in place. Install instructions are clearly written, have photos, and are easy to follow though they don't really tell you which tool to use where in the process.Function: Amazing so far. Really throaty growl from the intake when you start accelerating. I have a Borla cat-back that this intake complements well. Loud in a good way. Throttle response is noticeably better. I am not expecting massive horsepower gains but the Dyno test K&N did showed about a 14 HP gain. I recommend this if you want to improve air flow into your engine and get a nice mean sound. Worth the money to me.I got the plastic roto-molded version because the Black Hawk is slightly more restrictive material and the metal intake conducts heat vs plastic which insulates.

Everything I expect when buying K&N. Easy install, easy to clean, Adds a little pep when you hit the throttle. Works well, high quality.

Ordered this unit mainly to improve fuel mileage. Installation could have not be easier. Shipped fast. Super protection. Straightforward instructions. The only thing that would have made it simpler would have been to identify the socket (10mm) to remove the original airbox mounting plate and Allen wrench (needed to secure the new K & N filter to the new housing) - I tried a few Allen's until I had the exact fit, I don't remember the size. No modifications are needed for fitment. It looks great and all items are included to get the unit installed and operational fast. I didn't notice any increase in the sound during regular operation, but when you need to pass someone - that is when you notice you have a performance intake installed. You will certainly feel the improved performance and only a modest increase in sound level. Initial MPG seems to be about 10%. At that rate it would pay for itself in about 22,000 miles (but in less miles when gas prices increase, or when I pull a trailer). At that rate, for me, it would be 1 year.

I bought this hoping I would increase my gas mileage, but it increased the power quite a bit and it sounds so much better. It’s hard to keep my foot off of the accelerator so my gas mileage is actually dropped a little bit but it’s a lot more fun to drive.

Product fits and installs as expected. I would advised just looking up a YouTube video due to the paper instructions being not super specific. Very noticeable change in the sound of the engine, throttle response and fuel efficiency. Worth the money in my opinion.

This product is easy to install and provides great look with added power. Noticeable difference in power, and throttle response. Functionally this is exactly what I wanted for my 2018 Silverado 5.3.

If you've been considering buying this little upgrade, just do it. You won't regret it. Great quality product from K&N and super easy installation. I installed this on my 2018 Chevrolet Silverado LTZ 5.3 liter in a little over an hour. Highly recommend watching the installation video on YouTube.PROS: Slight improvement in HP and throttle response. Looks and sounds aggressive.CONS: Can't say you will notice an increase in gas mileage because you won't be able to keep your foot off the pedal for the angry "GROWL" sound you will hear from under the hood. Don't listen to the negative comments you read about it not sounding as good with the active fuel management system on newer Silverads. Granted, you don't hear anything when you first accelerate. When you hit around 1500 rpm is when you notice the extra gain in HP and then in comes the beastly "growl" sound. I'm sure if this was paired with an exhaust system, the two would sound absolutely amazing.If you're looking for a budget friendly upgrade with several perks, look no further. My only regret is not buying this sooner.
