MOOSUN 4 inch Cold Air Intake Black Tube + Heat Shield for 1999-2006 GMC/Chevy V8 4.8L/5.3L/6.0L Silverado 1500/2500/3500 Black

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.

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.

Package arrived damage free and product was well packed. For my aplication, 2004 GMC Yukon XL Denali, the coupler for mass airflow sensor was incorrect size, no big deal I made it work. Need to remove rubber gasket from OEM air cleaner box outlet to use on the supplied air filter and coupler. Fitment onto my vehicle was 90% simple and 10% fiddling with it to line up properly. Had to manipulate the mounting bracket to an appropriate angle for my truck. Also install the filter onto the pipe before fitting the pipe to the engine, save yourself the headache of double work, the filter is a tight fit and a shorter one that is wider around may be a better option. I purchased higher quality clamps but other than what has been mentioned the kit includes everything else as well as instructions for install which were if some help but those with mechanical knowledge will find this to be very much plug and play. Engine has a much throatier sound to it under acceleration as for fuel economy and HP gains we all know what we are getting into with intakes. This is a quality product for the money, if you're on a budget, this is the way to go.

This cold air intake worked perfectly for my LS swap! with the factory air box the exhaust almost sounded muffled, this air intake has definitely livened up the sound. Throttle response too. I haven't driven it enough to know if it helped Mpg or not. but everything was easy to install and has done a fantastic job. Looks great too. (Pictured is an LQ4 in an OBS)

just had time to easily install this intake on my 01 Tahoe. Wow what a difference in power and throttle response time. ive had brand name intakes and this is the same quality for a third of the price you can't go wrong here it sounds great as well!!!

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.

Decent quality, had to replace the clamps but other than that everything fits well and sounds good

perfect , same size, simple fit

Came with tons of extra goodies. Fit with very little modifications. Which is surprising cause i used it on my ls swap build which went into a 1958 chevy. Highly recommend

Required some custom fitment for the air flow sensor, air filter is a bit too long in my opinion, very tight fit.
