So i have always had many questions about cold air intakes. I have heard they are better but i have no idea what they are or where they go.Also I currently have a 1990 GMC Sierra, would i be able to get one on my truck? And if so would it even help?
A loss of money. Like the other guy said, maybe 1-2 horsepower. Which won't be noticeable to you, a 1/4 mile, just barely a dyno. Go look at your engine. The intake leads away from the engine, down towards the front bumper. This is to pull in cold air. All an aftermarket one does, is slightly increase the air flow. But it's so insignificant as to be basically pointless. The reason that guy's car sounds like that? Distortion. The exhaust is creating a soundwave, that is overpowering the microphone on his cheap camera. You can hear the echo to it, also. That's not the car, just bad recording.
Im not sure if they make a kit for your particular truck, but if they dont you could always make your own w/ a universal aluminum piping kit. Just get the right size, which in your case should be 3 or higher. A cold air intake is used to get outside air (which is usually cooler) and create a little bit more horse power and fuel economy. You see, the outside air is more dense and this would keep your intake temperatures down. Meaning, a cooler engine means more power. Of course you could just get a RAM AIR intake, which is usually just a Aftermarket filter at the end of the stock plastic tubing, which the filter would take place of the heavy plastic shroud where you stock filter is. Granted you lose maybe 2 pounds of weight, but now your forcing hot air into your truck, which is less dense and could eventually cause your engine to lose horsepower. *Cooler is better* Hope this helps
