MooSun 4" inches Performance Cold Air Intake Kit with Filter & Powder Coated Intake Tube Pipe for 99-06 GMC Chevy 1999 2000 2001 2002 2003 2004 2005 2006 V8 4.8L/5.3L/6.0L (Black&Black)

Works as it should and bright blue. Blue is my color.

Great Cold Air Kit works excellent.

Works good. Faster throttle response. The only issue I have is it needs a 4 inch to 3 inch reducer for the mass air flow sensor.

The media could not be loaded. 06 Chevy Avalanche 5.3L….This air intake is definitely worth it for its price! After all, it is just an air filter and the tube to suck air so save yourself $150-$300. Install was easy and has a pretty decent throaty sound. There is a bit more throttle response and hopefully better fuel economy. I do agree on the quality of the hose clamps but they work and could be better. But overall I’m satisfied with shipping speed, quality and functionality.

It works as intended and looks the part as well. Doesn't effect afr on my truck and I can get a little induction sound from it as well. No, it's no monster on my stock 5.3 but it gives a good vibe and the price was plenty fair.

Honestly I didn’t know what to expect for 55$ I’ve bought cheap cold air intakes before for my other projects I’ve been a mechanic for about seven years I hve all my saw certs I’ve worked in many shops but like anyone I have a budget and I can say by far for 55$ this is the best quality cold air intake kit I have ever received it was packaged well came in damaged and with everything I need and instructions which alone is more than any of the cheap ones due the fact is a new air filter on the cheap side is 20$ so for 35$ more you get a whole cold air set up with a quite larger than expected air filter which means more air flow which means you can create more power and of good quality that you can wash and reoil with a kn air filter cleaning kit quite easily this is defenetly worth the one u you pay for I honestly believe they could charge a 100$ for this kit I might start buying them and doing i stalk kits on the side for 150$ and make some quick cash the kit is great for the price you pay no complaints

Looks great in the engine bay and pretty easy to install, the instructions had a little ambiguity which lead to some confusion on the install, the weather stripping seems quality but I wasn't sure exactly where to put it and the panels that separate the bay from the intake didn't line up perfect. Other than that, again looks great, my buttdyno feels more power, and it makes great sound out of the front end now. Well worth the money when others are over $300 for the same gains.

The good is that it does work and it's cheap. The fitment of the support bracket underneath could have been better and seems very weak. And the connection of the rubber sleeve that goes onto the mass air flow sensor was way too big. You can only tighten down rubber so much. I was afraid that the mass air flow sensor would shake out of the rubber sleeve. I had to remedy this by wrapping a 1 1/2" strip of rubber roofing around the sensor 2-3 times so it would fit much better. The backside rubber strip was sprayed with a strong adhesive to keep it in place. Which led me to replace all the 4" hose clamps. They are terrible and when you tighten them down the tightening screw goes inside the backing plate bending and rounding the hose clamp and not allowing you to ever be able to tighten it to the proper pressure for strength and seal to hold everything in place. I replaced all the 4" clamps with stainless clamps (cost $8-$10) so I wouldn't be worried about pieces coming undone on the road causing wrong reading with the sensor or worse getting bad debris being sucked into my intake. A few small things would make this a very good kit. Luckily if you are handy in the garage this kit should work for you fine. And any video comparisons show no significant difference between a $60 kit like this one compared to a $250-$300 kit by top name brands.
