Decent instructions. Quality materials. Kit complete with hardware. Easy fit. MASSIVE Improvement in performance. Only gripe is hose clamps provided require a 19/32 socket instead of standard 5/16. Great buy, similar retail $200 and up! Very happy and recommend. 30 min - 1 hr to install.

Well the other reviews weren't lying about the poor quality instructions. Couldn't make anything out from the enclosed instructions. If you can operate a screwdriver and a socket you got this. The enclosed clamps will be replaced. Cheaply made but will suffice till I get more. All in all, nice cold air set up. You can pay $300-$400 for a name brand if you want too. I'm not. The filter could be a little shorter, it's tight up against the inner fender and seems to me to be holding the intake tube out away from from the air box. The bottom mount for the rubber vibration bracket is just a hair off, again I think it's the filter being too long. Well worth the money. Definitely increased air flow. Don't know about fuel mileage yet. As for the noise levels, my truck is loud, exhaust... Enclosing some pictures, hopefully it helps.

4stars because it gets loud @2k Rpms, sounds a bit aggressive, not a bad thing just unexpected from a 4.8l. Was a pain to install , lower bracket is too short to be secured to the bushing mount , other than that clamps are tight, should hold.

The media could not be loaded. The included instructions were dark and blurry. I looked at the listing picture on Amazon to give me an idea how to line it all up. On my 2002 Silverado, I had to cut the middle tab off of the intake pipe in order to make it fit where it wasn't pressing up against top of the upper radiator hose. I also had to do an alternative mounting method for the left side of the bottom plate of the partial airbox they give you. I also had to cut the lip of the upper fan shroud for pipe and elbow clearance. You'll see when you try to install them. Because this kit is universal for a bunch of different models, I'm sure there's a use for that screw hole tab in the middle of the pipe. But not on my 4.8 V8 2002 application. I cut off the tab with a cutoff wheel and ground it down smooth, then touched it up with flat black rust oleum. For the bottom plate of the 2-piece airbox thing that they give you, you have to put the bottom plate in first (that's the one with the angle part, not the filter hole slot.) I used a silver paint marker to line up the two pieces as they would be in the final position, then marked where I need to drill an additional hole in the bottom plate to mount using the factory screw holes. Pilot hole was 9/64", second bit 1/4" to allow enough clearance for the factory 10 mm bolt to go down in there with no binding. You can get away with a smaller bit, but I have a lot of those two sizes so that's typically what I use for these. For the left side of the bottom plate, I was unable to use the factory holes, so I drilled a pilot hole using the middle of the 3 provided holes on the bottom plate, widened that middle hole to 1/4" (don't make the body mount hole too big) and used a #14 hex head sheet metal screw to anchor it in the middle. I can't remember what size the pilot hole has to be for the #14, I just eyeballed it to get the correct drill bit size. Just line up the bit over the top of the length of the screw to make sure of that the bit is a little narrower than the teeth of the screw. I used a 10mm socket and impact to screw it in. Just be careful and don't use too much force or you'll strip it. If you're not confident about your feathering technique with the impact gun trigger, just tighten it by hand with a ratchet. Once your "airbox" is installed, it's fairly easy to install the pipe assembly. Make sure the screen on your MAF is on the air filter side. Don't tighten up your hose clamps until you get your pipe and filter lined up the way you want it to be so that it sits low in the box and won't interfere with your hood. Pay careful attention to the upper radiator hose clearance because you don't want that metal tab to press down into the hose while you're driving cuz it'll eventually wear through and you have a busted hose and an overheat. Protect your upper hose like I did with corrugated plastic sleeving if you need to. I'm happy with this intake. Nice, fairly well made parts. Sounds a bit louder than the resonated facory crinkle tube with a nice growl under full throttle. Quiet as factory at idle. Mild to moderate improvement in acceleration. More of a smoothing of the powerband and removal of hesitation in acceleration, rather than a gross horsepower gain. After a few days I started noticing the difference on the highway as well because now at about 2,000 RPM at 80 mph, where I was a little bit higher with the old intake and the engine seemed to struggle more to maintain 80. Now 80 mph feels comfortable and smooth. Merging on to the expressway is a little easier coming off the on-ramp with a little bit quicker acceleration than before and it's a lot smoother to accelerate under Full Throttle. I'll be going back to straight piping it shortly to get rid of the restriction of the muffler too, and get back that nice throaty Vortec/LS exhaust sound. I like this intake a lot, and I'm glad I did it. I may upgrade that cone filter with a better aftermarket performance filter eventually.

For the money not bad at all. Install was easy but the coupler from the intake pipe to the MAF sensor was to big but I wrapped some rubber around the MAF sensor and made it fit. Had to tweak the heat shield a bit but nothing crazy. Other than that it works like it should. Sounds cool lol

Immediate changes to horsepower and fuel consumption. The restrictions OEM intakes have are completely nonexistent with this. Works good and easy to install...

First of all, I would start off with the instructions that are very lousy no true detailed instructions included. Besides a copy of instructions not explaining step by step and part by part being used in an order sequence for assembly you have to figure it out yourself. second of all the rubber boot sent to fit over the MAF is a straight 4'' which the MAF isn't 4''. A stepped boot is needed in order for it to fit properly nice and airtight 4'' reduced to a 3.5'' should be included and would work out great. if not, you are stuck using the 4'' to 4'' boot not a good fitment and pushing the air filter towards the fender well and rubbing on the fender well and making rattling noises as you are driving. In order for me to make it fit properly and have it not rubbed on the fender well I had to order a stepped boot 4'' for the pipe side to a 3.5'' to the MAF side I also had to use a cutting wheel and cut 1'' off the pipe going towards the MAF side due to it pushing the filter farther out and rubbing on the wheel well even more than what it did. after all this was done fitment was perfect. But let's remember I perfected the fitment by all the additional steps and parts I had to order, in order for it to fit properly so an additional $25.00 were spent on the stepped boot used in order to make a nice airtight fitment.

Great for the price, a bit tricky on the install I see most people put it on incorrectly The air box fit well The boot on the throttle is a bit soft I plan on replacing that part
