K&N NextGen Cold Air Intake System: High-Flow Cotton Filter: Compatible with 2019-2025 CADILLAC/CHEVROLET/GMC Escalade; Silverado 1500; Suburban; Tahoe; Sierra 1500; Yukon; Yukon XL; 50-3110

Fit, form, and function are all PERFECT. I wrapped up the installation late in the evening and managed to reinstall the MAF sensor backwards (don't do that!) so the initial startup was less than desirable, but my mistake was obvious and easily fixed. Once everything was corrected, the truck started right up and purred like I was hoping for. That purr turns into a growl on the freeway and reminds me of my younger muscle-car days. I installed it along with the addition of an AFM disabler and so far I'm seeing a slight (like .5) increase in MPG. I'm sure there's a little more there but it's still too early and too fun to get on it for an accurate overall increase. The instructions are decent. I did resort to some YT videos, and I was a little disappointed that some things weren't preassembled as they easily could have been, but nothing worth docking a star for. All things considered, I would definitely recommend this mod. The extra airflow and power boost is well worth this minor investment!

2 hour install, Took my time. Pretty easy following the supplied step by step instructions with pics. I read where the instructions wasn't worth a crap, maybe they've revised them, I had no issues. First test drive was amazing! Sounds mean! Until I get used to it, I think my gas mileage might suffer a bit. I like to hear it suckin. UPDATE; installed on 2024 GMC Sierra 1500 4x4 5.3l. I did not unhook the negative battery terminal, never threw a code however after installing I ran down the road a few times not noticing my mpg. The next morning I noticed the mpg was 12.3, I was sick about it all day at work. Researched a lot of fixes which folks tell all kinds of stories. I noticed on my way home, after work, that the mileage was slowly ticking up. 3 miles later I arrived home, it got up to 13.6. I had a glimmer of hope. I drove that afternoon on a 55 trip. It had gotten up to 24.0. I was overjoyed to say the least. So in short it needed to recalibrate to the new conditions. Next day I seen 24.6 plus I had my foot in it a few times seeing 90mph once. I hope this helps someone to give some insight of what you might experience as well. I love it!

Wow, this was a great choice. The installation was not difficult at all. The hardest part was getting the air box into the compartment. It’s a tight fit. Once in, it lines right up. I have a Black Widow edition Silverado with the 6.2L. So the truck has custom dual exhaust. It had a strong exhaust note before but after this, man it sounds good. It gives it a deeper growling sound. When I step on it, you really can hear that 6.2L breath. There is a noticeable jump in power. You are not going to get a noticeable difference that will really push your hair back but it’s still a noticeable difference. In my opinion it’s the torque that you notice most. The 6.2 is a strong engine in itself but with this much on it, it feels like it is launching even faster. I have a lift and 37 inch BFGs and it spins those with easy. At times it’s hard to keep traction when taking off. I love this intake. You will get a filter notice and once you need an oil change on my model but no engine lights. Just bolt on and go.

Installation of the K&N Blackhawk Cold Air Intake on a 2025 GMC sierra 1500 Crew Cab 5.3 V8 was a breeze. This is the first cold air intake I have installed and it took about two hours. The instructions are very well laid out and include pictures, which is very helpful for someone like me who is just learning how to do car modifications on their own. The product itself is excellent. Love the way it sounds and I can definitely feel a slight power increase.

Seems to be working good with the accepting of my truck constantly giving me a check air filter warning. I just deactivated the alert. Instal was not horrible thanks to online Youtube videos but included instructions were not very good. I am seeing an increase of about 4-7 miles per gallon and love the sound. Increase in HP is not really noticeable.

Fit perfectly makes the truck sound awesome increased horsepower and performance Love it

Very easy install, only took me about an hour. Throttle response is night and day different. I was surprised about how loud the engine is now from under the hood. I knew I would hear a difference, but wasn’t quite expecting this! The 6.2 really sings now! Sounds healthy.

It is loud! Shocked not only by how it sounds, but also by how the power is noticeable.
