CAI's

[jomulk56]

What do you have? How do you like it? Is it worth the money? Did you get a good power gain from it?

I really don't know much about cold air intakes. What do they do for you?

They get colder air into the engine. With colder air you get more horsepower, and more fun driving.

Never really messed with them. I guess I need to look into that

Honestly, I've never found an CAI to be worth the amount of money. Granted, I have had one every vehicle I've had, for the same amount of money you can get a custom tune and see better results. If you're looking to improve MPG's, I did notice it did help. Clocked a consecutive 1mpg gain in the same driving conditions. As far as power goes, I noticed nothing really. The stock intake box flows quite well, the only thing you might want to get rid of due to visual appearance would be the tube w/ resonator on it. You can literally make your own from Home Depot supplies for around $30 and get the same results as an aftermarket intake.

I've actually been thinking about making my own tube. What do you need from Hoe Depot to make it?

Not sure how this will relate to anything but a NNBS but here's a how to for an intake:

Stock intake




New Intake:





List of things used
4" 90* elbow with a male/female end
2' of 4" black PVC pipe
2' of 1/4" flex fuel line
4" to 3" coupling
4" coupling
1/4" to 5/8" barbed fitting
1/4" hose clamp

I assumed you used PVC pipes, just wanted to make sure

Actually that looks like black ABS tubing...but same difference, it just looks better under the hood because it's black, and not white lol.

I put a K&N FIPK on my '99 Envoy hoping to see a gain, but it actually decreased my mileage. That was back when I was young and MAF-retarded though - I probably added too much oil which more than likely found it's way onto the MAF element, causing a bad reading, which lowered my mileage. Not sure though.

I did a homemade FWI (fenderwell intake) for my 02 GTP, and that thing worked great...the supercharger SCREAMED when I got on it. Scared the little ricers in my neighborhood, lol.

I wish that I had enough room on my Yukon to do the same thing as pictured above, but because of the mechanical fan being placed so close to the intake tube, there is not enough room to use ABS tubing since it's substantially bulkier and the bend isn't as tight.

The AEM Brute Force intake is actually an excellent design, and you can get knockoff kits on ebay for under $100 if you look hard enough...filter and heat shield included. They flow just as well from what I've heard. Thats what I'll be doing, especially givin the problems with my stock intake (see my tuning thread).

looks to me that the cheapest way to dress up the engine compartment AND have good-enough airflow would be to get the following parts:

Airaid 200-912 MIT (Modular Intake Tube) for $110
Air Hog washable oiled-gauze filter for $9

you can buy the whole Airaid Jr. setup for $150 - but you're paying $40 for a $9 filter at this point

so for $119 - you get a little more intake sound at the best price possible which also improves power (most likely sub 10hp) and mileage...

in my case - just the airfilter (and a new fuel filter) increased my MPG by 1.1MPG, next step is to add the $109 tube from Amazon
