Lookin For Cold Air Intake??

K&N is good IMO; however, they do not advertise it as a "true" pure cold air intake (CAI), as the filter does not COMPLETELY seal out all heated engine air the filter can draw from. Advertizers that sell K&N list them as CAI, but K&N web's site states that are not complete CAI. You'll pay a lot more for one of those kits.
To the poster that bosted a 15 HP increase with his K&N install: How could you tell? Did you dyno the truck before and after the install? Or do you have another way of measuring HP gains?
Just interested. I too installed one, but I never bothered to measure HP increases.

A CAI doesn't boost HP by itself to a point where you'd notice it. It will however increase the throttle response and that will make it feel like it has more power. A programmer is what you need to get for true HP gains. A CAI with a programmer module can give you 15hp, but not the CAI by itself. By itself, a CAI will give you maybe 5 extra ponies. As for air-raid going out of buisness, I havn't looked into why, but it could be a bunch of reasons that have nothing to do with inferior quality. I've run CAI's on my cars and trucks for years and I've never had an issue with dammaging it under its warantee, or damaging it at all for that matter. They're just ducts with air filters. If you have an air raid, don't worry about it, if you wan't to pick one up for cheap cause they're closing their doors, I say go for it.

The CAI is pretty much just a tube to the throttle body with a filter on the end of it. Metal or plastic shouldn't make a huge difference since there is so much air circulation under the hood, that any radiant heat it picks up will be disapated by cold air convection. In fact, a short ram wouldn't be much different in one of these trucks than a CAI unless you spent a lot of time at idle or stuck in traffic. The main thing with either a short ram or a CAI is that you are opening the airway for the engine to breath better. One of the key differences between all of these systems is the air-filter. Is it a dry filter or an oiled filter? Is it enclosed or open? Secondary things you want to look for are what kind of hardware it uses and how it routs the ducting. There should be no reason to get a kit that requires you to cut anything, or drill anything. Check reviews on the kit you're looking at. If they have people saying that the kit was missing parts or lacked instructions or customer support, get a different one. The stock intake isn't so restrictive that it will give you 15 extra hp by putting on just a CAI. If you add a programmer module and open the exhaust up, then you may see up to 15hp on a gasoline engine.
I do have an Edge Programmer and 3" CBE so i hope i do see 15 hp does it help with gas mileage as-well??

It can help with gas mileage if you set it up that way. Usually when you open up the engines exhaust and intake you want to set it up for more power though. You have to chose one or the other, but you can't really get both.
The CAI will give you a better throttle response because the engine can get air faster than trying to suck it through the stock airbox. When you have that power available, you tend to put your foot in it more off the line, so your gas mileage sucks. If you have a programmer and you set your truck up for more power, you'll be buying more gas than you do now. If economy is what you are chasing though, a programming module will allow you to customize your computers algorithyms to give you better fuel efficiency, but you lose that throttle response and power increase. On the upside, gas prices are way down from last year!

A metal intake will heat soak and cause a raise in IAT over a plastic one. I have seen as much as a 25 degree difference.
Now these are my personal experiences. IF someone else has different then please post them up.
