K&N Cold 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.

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.

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.

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.

Very easy to install. K&n makes a great product

Let me start off by saying that this is a very nice looking intake. Love the sleek black look, a bit more subtle than the spicy chrome version but enough to be something to step back and nod your head looking at it. When you get on the gas in gives you a nice growl. Not sure of the performance or mileage gains, but in my opinion it’s okay to admit that we like the way they look and sound, and I know for sure the performance has to be AT LEAST marginally better because we know that it’s breathing better. Only argument one could have is that the factory air box does indeed force the air to come from the inside of the fender well with a gasket that connects that cavity to the box. Once you install one of these, one could hope that it’s still pulling most of the air from that cavity, but it’s obvious that it will now also be pulling at least slightly more warm air from the engine bay. I would venture to guess that once you allow the engine to breathe better, then it will also benefit more from a tube than it would had it had a stock setup.Now for my two gripes.1.) This Blackhawk was advertised as having this really nice polished aluminum badge welded onto the tube. This looked very clean and in my mind fit perfectly for what I had in mind for this truck. When a guy loves his truck and every detail matters, and you receive an intake with a fancy metal sticker instead of the welded aluminum badge you saw in the photos when you placed your order it’s a little upsetting. I probably would have bought it anyway, but spending good money and receiving something that isn’t EXACTLY what you were lead to believe it is is a huge pet peeve of mine.2.) This unit is sold as not having any CARB OE exemptions and will not allow you to ship this to California. Having done my research there is indeed a CARB EO for this intake to be used in a 2015 Silverado 5.3. I assumed that since they were not allowing you to ship this to California that it would not come with a CARB OE sticker. I went through jumping through all of the hoops to ship to a friend out of state to have it shipped to me, and filed for a replacement sticker only to find out upon receiving it that there is a CARB OE decal included in the kit.Great product, but the seller should replace the photos in the listing with the photos of the item you will actually be receiving, and allow this to be shipped to California since there is literally a CARB OE decal included in the kit.Hopefully this helps somebody.

The throaty growl sounds great under acceleration. Slight performance and mileage improvement but you in order to see the mileage improvement you don't get to hear the growl. In using my cruise I see between 5 and 10 percent increase in mileage ie from 15 to 17. On open freeway it has improved from 19 to 21 on average. Very clean install. I would recommend the dry charger wrap to increase its life and reduce the frequency of cleanings. The wrap also improves appearance as it comes in black, red, and blue.
