So, i just installed this in A Yukon XL, 5.3L. took me an hour and a half and I am NOT a mechanic. A couple of things that hopefully help others. Step 13 shows the connection tubing with the number (that differentiates the 5.3L from the 6.3L toward the front of that rubber connector. Let me tell you, if it is in the front of the connector, good luck ever getting the filter piping to fit into that connector! Put that number toward the back (toward the throttle body) and then the piping will fit into the connector, no problem. This was an 1/2 hour issue for me, a lot of swearing, and multiple glasses of bourbon. I would say in general the directions are easy to follow but should be more specific. For those, like me, that are not as mechanically inclined, “attach with the provided pieces” is not all that helpful- I got everything put together tight and fine but was left over with two washers and two lock washers. I am sure that some of the parts I screwed in are supposed to have those, but I don’t know which ones so I am just telling myself they sent extra parts to make myself feel better. Again, anyone mechanically inclined probably knows where those are supposed to go…but I didn’t. Took it out for a test drive and I will say, great engine sound and noticeable low end torque increase. As for gas mileage, too really to tell. I know for me personally, it’s gonna hurt my mileage because that sweet sound under heavy acceleration is delightful. If you have better impulse control I would be willing to bet it will increase gas mileage.

2018 GMC Sierra 1500 Denali with 6.2.Installation was very easy.Not overly impressed with the quality of parts. As mentioned in other reviews, the plastic hose barbs are probably best served by throwing in the trash and replacing with brass or stainless. Not to say I had any issues with them (cross-threading or otherwise).Also, I am not fond of the valve cover breather hoses which are forced to make a compound bend and partially kink.The intake tube is paper-thin which, Im sure is to save weight, however, mine appeared to have been dropped or crushed at some point. I was able to reshape the opening back to a mostly-round form with my hands.Also, regarding the intake tube, this one is actually smaller in diameter than the factory intake which is why K&N uses a reducer/adapter at the throttle body to shrink it down. I cant see how REDUCING the diameter of the intake results in IMPROVED or INCREASED airflow.I could not discern any palpable gains in performance although my initial test drive was rather brief. I might update this report after a few more miles.My exhaust is a single Flowmaster Super 44. Noise factor as a result of this intake is not a concern. There is now a notable rumble or growl from under the hood under load as well as some increased vacuum but again, mostly under heavier throttle and not so much during “normal” driving.One photo shows the kit as intended by K&N and the other photos are after I replaced the plastic barbs with 45 degree stainless elbows and blue silicone hose.

I did buy it used as a warehouse deal, and it was missing parts that i had to fabricate, so check your box before you take parts off the vehicle. I’ve had a K&N CAI on every gas V8 I’ve owned without issues. Couple this with an AFM override module and your Chevrolet will run a lot better. You will get better fuel economy once you learn to keep your foot out of the skinny pedal.

Very easy to install. Works as advertised. Great “growl” when you accelerate.

My seirra has a functional ram air hood. So I finished inclosing this box once installed(mostly the bottom and back where factory drew air from wich I made removable plate for switching filter). It sounds amazing and work like a beast!

Haven’t had it installed long enough to record mileage, took my time to install kit after studying directions and love the sound of kit when I accelerate to on ramp of interstate. As for value for the money, that remains to be determined, but it was cheaper than adding duals, headers, etc.

Box was delivered and was damaged. Picture included. Upon inspecting components inside the box, the intake tube was smashed/deformed. I was able to take a wrench and straighten it out enough. For the money, it would have been nice if everything delivered in good shape.After install, truck sounded great and performed well.

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.
