The first this I wanted to do when I first got my truck. But on MAP engines you will force lean your air to fuel mixture which the ECU is already keeping to a 14.78:1 air to fuel mix as it is. Better to keep any air increase moderate at most, to allow for more base timing advance.
If you're lean to start with, your engine will not tolerate any substantial bump in base timing. Shooting yourself in the foot big time.
This is EFI, not Carberated. W/ an ECU, you must work with it. Complement it, not ignore & overpower it. Because It will always win in the end. You won't like what it may cost you when it does.

I think the thread you're talking about was titled something like "look what $50 and a weekend can do" or something like that. It did look sweet, but a lot of people on here will be quick to tell you that the "cold air" intakes that just take air from your engine bay are hotter than the air that comes from the pipe leading to the front of your hood

Anyone got any pictres of these trucks with snorkels? I am starting to think its he only way to go. I had an idea to rip this filter box out of my truck, take so exhaust tubing and weld it up to fit the dual intake on the throttle body, then buy a round k&n high-flow, and make a fiberglass box with a 4" hose going into the fender well, and two kore smaller ones going through the firewall and underneath those grates at the bottom of the windshield, oh, and about 10 1/4 holes drilled in the bottom of the box to solve water problems. So basically if the fender well gets drenched, which is possible sometimes but only for a second, it will pull air from the grates, and when rain or a wave hits hose grates it pulls from the fender well. Sound like this will work?

PVC pipe is great, it's designed to keep water IN so it can do a great job of keeping it OUT.
I made a PVC intake tube for my S10 because of the motor I put in there. But there are snorkels you can just buy, those are the first two pictures I found of our trucks with one.
Waterproofing helps, but remember it's not a submarine.

pvc is cheap enough but how big of a diameter should i get and what should i water proof?

Im not to big on cutting a hole in the fender though. What other options are there to get clean air and a little more water protection? Do u think my idea will work?

I dont think it would work any holes in the intake it would draw from it even if theres water it will just suck it right in. you could get some kind of valve to work that only lets in air or something it might work but just a spoon full of water is harsh on an engine remember water does not compress easily at all.
