Rough Country Cold Air Intake for Chevy Silverado & GMC Sierra 1500 (2014-2018) 5.3L/6.2L - Increases Horsepower, Towing Power & Acceleration

Perfect fit for my 2015 Silverado 1500 LT with the 5.3Easy to install and it will increased my gas mileage by about 2 MPG. Plus is sounds great!

Great product, as soon as I stepped on the throttle, you could hear a large and throaty difference from the normally very quiet 2015 gmc sierra 1500 sle with the 5.3l. It does have the dod delete switch on it. I do a lot of work to my own vehicles, this was a breeze. Instructions, parts, installation were straight forward, came in perfect, and took about 45 minutes cause I took my time. Looks very clean in the engine compartment.. Not sure about any of the benefits yet, will try to update

Install wasn’t hard, missing small clamps and one of the larger clamps busted, so I had to make a trip to Advanced Auto to get the necessary hardware.Like I said, install isn’t hard, if you are half way mechanically inclined, but the directions definitely lack clear detail.Once on, works great, noticeable sound and increase power at higher RPMs.

Just installed this in my 2018 Silverado. Installation was relatively easy and the instructions were easy to follow. I love the way it sounds now that the motor is finally getting air! You won't be disappointed with this, especially for the price!!

The pipe was damaged, but the box wasn't damaged so kinda just seems the packing could be better. *INSTALLER BEWARE - CHECK THE INSIDE OF THE PIPE BEFORE INSTALLATION!* I had a bunch of machining debris inside my pipe that I had to blow out that would have for surely came loose in operation and gone thru my engine.The installation instructions said that the fittings for the breather hoses were 3/4" wrench but were 13/16's wrench, and also said later on that being the barb style fitting it wouldn't need hose clamps. Perhaps if the hose that came in the kit was next size smaller that would have been the case, but unless I wanted to pull unmetered/unfiltered air into the engine you def need hose clamps on those fittings. Nice thing tho at least for the GM 6.2 L the hose was actually big enough that you wont need the not included smaller hose clamps for that connection because you can firmly fit the hose over the valve cover fittings.The 4" hose clamp for the throttle body connection (only get one) broke immediately upon tightening down so I had to grab another hose clamp from our parts room.The instructions say that it's an oiled filter, but mine was dry and came with no oil...so here's to hoping it should be a dry filter now.Other than that most everything fit together nice and looks good and sounds mean when you give'er the onion. Pro tip tho, when mounting the air filter shield into the engine bay, don't tighten the mount bolts down until last. You will have to wiggle and adjust it around when putting the pipe in to have everything look and fit right in the engine compartment. Then tighten it down, it's a rather sturdy looking set up. I had an extra 3.5" clamp and coupler when I was done. Also the 5.3L accordion tube throttle body coupler will actually fit perfectly on the 6.2L throttle body opening, just need a lil soapy water but will at least alone for some flexibility for the engine torque moving the block around.Much better throttle response with this kit than factory. Doubt I picked up any real power (nothing notable to me), but the sound and room opened up in the engine bay now is worth the money alone.

Gave me an extra MPG so worth it, and a good rumble when accelerating! Installed in 15 minutes.

I’ve been an aircraft mechanic for 26 years. I’ve rebuilt aircraft for Virgin Galactic, and was in the import scene for a long time with my Evo making Cover of Dsport (March 2012). I’m well aware of what true quality is, and this is not it.The only reason I didn’t remove it and go back to stock is it’s 98 degrees outside.The intake pipe is pot metal aluminum. Absolute lowest quality aluminum. That’s ok though, it matches their packing which is trash cause the pipe was scratched to bare metal. Thankfully they sent a badge which I used to cover the crappy pack job.The 2018 Silverado has quick release vent tubes so installing the hoses required worm clamps, guess what… none in the box. Surprise.That’s on par though with the other clamp which came cross threaded in the barrel nut and would not release or tighten. I humored myself and the bolt never moved. The clamp twisted and bent though. Used a factory clamp. The filter makes spectre look like K&N.I wish I could say anything good…….. it’s lighter than stock but that could just be because it was missing half the clamps.Save your money and buy something else. Also for reference, I have a 2001 Suburban with 5.3 and I installed a 57.00 Amazon eBay intake. It is significantly higher quality than this Rough Country attempt at quality intake.People giving this 5 stars either got lucky or have very low standards.If you wanna see what quality looks like. Google Japanese ARC intake.
