Airaid 200-919 M.I.T. Modular Intake Tube

All of the parts needed to install were included. Quality parts, no junk here.The part is equivalent in quality to a factory GM part. Well made and easy installation. It seems like it does help performance. I bought it because the stock piece looks very restrictive. Quiet but restrictive. The truck seems to have a bit more power, but that may either be wishful thinking or the sound made during acceleration makes it seem faster. It did help gas mileage slightly. An average of 0.2 MPG over three months. Not a lot, but a good result for $125.

Very good quality built intake tube. All connections are very tight so no worry about air leaks. Makes engine bay look alot nicer and has a little intake sound when getting on the trottle hard. Having a tuner I can watch intake temps stock setup was always 3 to 5 above ambient temp and I'm at 1 to 2 degrees now.

The 5.3L engine in my 2005 GMC Sierra 1500 runs smoother and quieter- wasn't expecting that. I installed it with the stock "off road" air cleaner box with a K&N flat filter. The truck has a cat back exhaust installed and used to be pretty loud at all rpms, it growled below 2,000 rpm and droned at highway speeds. Now the growl is there albeit smoother and the drone is basically vanished, so much nicer on the freeway. The engine idles and runs smoother, installation was very easy, fit & finish excellent.

Ive had the Airaid 200-919 on my 2005 Silverado 5.3L for 5 months/8,400 miles. Just removed it. The quality is first rate....the tube itself, connections/clamps and instructions all great. Fitment is excellent. Installed with OEM filter box with Wix paper filter. Noise from air entering throttle body increased dramatically from 1/2 throttle up. MPG same in town driving (I am a Realtor in PHX) but fell 1.5 - 2 MPG on highway. When towing uphill the transmission doesn't shift down like it did without the Airaid tube due to more air/power and the MPG didn't change. The reason I took it off is simply the MPG drop when not towing on road trips. If you tow and/or like the power/noise I recommend this item. I like the noise/power but the MPG decrease on road trips not towing is why I'm removing it.

Better airflow through the radiator & ac condenser. Better throttle response. Much cleaner look than original equipment. Has a nice sound when you get on the gas but not obnoxiously loud like an open element system.

Looks much cleaner then the factory intake tube. There is definitly a noticeable increase in the intake noise due to no longer having the silencer, which some may not like. As others have stated, the rubber coupling which attaches to the MAF could be longer I had to pull the airbox towards the tube in order to get it clamped together.

Good functional product. Installation was easy as can be. But keep in mind, it's a plastic tube. It won't magically make it seem like you've installed a supercharger. I put this on a '06 Silverado 4.8l 5speed. Also put in a K&N filter. Can't say I noticed a power boost but throttle response is improved. But the most noticeable difference is surprisingly the exhaust sound. The small block burbles and roars like an old big block now. If that's what you're looking for then that alone is worth the price of admission.

My overall favorite part of having this in my truck is the sound the engine makes. Very throaty and aggressive. I also have seen out about a .5-1 mpg increase from the truck as well.
