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

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

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.

I have to report the Yukon lx has much improved gas mileage. Old average 12.4 mpg. New mileage since install 14.6. That’s way more than expected and definitely a little extra power when on the throttle. Maybe 10-15hp. Enough to tell the difference from stock. More intake noises but the good ones. No complaints from the wifey about noise, or better throttle response and increased fuel mileage.

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.
