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

I've been a car enthusiast for years, and installing the K&N Cold Air Intake System on my 2014 Chevrolet Silverado was one of the best mods I've done. Right out of the box, the quality is evident – the high-flow air filter and heat shield are built tough, and the installation was straightforward with clear instructions, taking me about an hour in my garage. The real magic happens on the road. Performance-wise, there's a noticeable increase in horsepower and torque; acceleration feels smoother and more responsive, especially when merging onto the highway or towing my boat. It's like the engine breathes easier, delivering that extra punch without any lag. And let's talk fuel mileage – I've seen a solid 2-3 MPG improvement on my daily commutes and longer trips, which adds up quickly at the pump. Paired with the throaty intake sound under throttle, it just makes driving more fun overall. If you're looking to enhance your vehicle's performance and save on gas without breaking the bank, the K&N Cold Air Intake is a no-brainer. Highly recommended for any truck or car owner!

Easy instal. Sounds absolutely amazing. Looks bad ass. Solid build and more power.

This intake was very easy to install looks clean and sounds very good on 5.3 suburban.

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.

Installed on 2018 suburban 5.3 v8. Super easy install. Everything is good quality. Sounds really good and can tell I have better throttle response.

Overall this intake is great, it was a very simple straight forward install and fit my 2018 5.3 z71 perfectly. It is definitely a noticeable difference, you can hear the air being sucked in through the cone filter and it wakes your engine up. The one thing that I didn't like about this product is the hose fittings for the PVC hoses to the intake tube. The fittings are plastic and cross thread easily and can break or loosen, along with the threads in the tube are nuts welded on to a hole that is size for size so while one side the fitting went in fine the other stopped thread engagement because the hole in the tube was slightly off form the hole in the nut. I had to take a drill that was just under the thread size and drill thru a little bit so my fitting would screw in. After that my fitting screwed in but was loose from cross threading in prior attempts. I ended up buying new stainless fittings to replace the plastic ones it came with. Also it did not come with hose clamps for the PVC lines. I'm a mechanical guy so I was able to figure all of this out and make it work but someone who doesn't know how to wrench would have been in for a headache.

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.
