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!

easy install, dont know if i am getting better mileage but the awesome sound offsets that.

This thing is the absolute worst idea to ever put on my truck. The problem is now it sounds even more aggressive and throaty when I step on the gas so all I ever want to do is put my foot to the flor. I have yet to notice an impact to gas mileage from this but the installation was really simple and fit flawlessly. Pay attention to the screws in the directions and you'll have no problems. The filters are great and definitely recommend them for any car enthusiast.

Was what showed k&n is always been a good product woke up that 5.3

K&N always quality products

Took about 2 hours to install, instructions are very easy to read and well organized. Fit like a glove and sounds awesome. Definitely feel a peddle response increase in peep and horsepower.

After looking at how K&N does their box on the inside of the engine compartment & how they use a metal tube across the engine for the air flow which to me isn't a good use of materials because what conducts heat more? A metal tube or a heavy walled plastic tube? METAL DOES! And how do you know you are getting a precise seal on the metal box the air breather is in? You don't! Which also brings to mind that the metal box the air filter sits in is also METAL! All I see is you having a lot of metal in how they do their set ups introducing more heat into the equation than necessary. So then WHY do they call it a "Cold Air Intake" if all they are adding is a lot of heat thru conductivity?
