Heres one for those of you that take your trucks and suvs through deep water. The best way to make sure you dont damage the motor by getting water in it is to put a snorkel on. This way the level in which the water would have to be to kill the engine is above the hood or even roof.

Most everything you need you can get from your local hardware store. The parts you need are:
3" PVC right angles
3" PVC 45 angles
3" ABS pipe (Like PVC but weaker)
4" air hose for a air cleaner (Like dryer vent hose but stronger) Get this from local auto parts place
PVC pipe glue
A tube of caulk

Tools
A cut off wheel
Caulk gun
Drill
1/8 drill bit
metal file
Chop saw
1/8 metal screws

Installation:
Your first step is to cut a hole in the fender. use a cut off wheel to do this.

Now set up how you want the pipe to run from just inside the hole to where ever your external location will be.

Make sure the air cleaner is sealed with caulk so absoleutly now water can get in it.

To make the snorkel hose, it needs to be attached it to the air cleaner housing. Cut a piece of ABS and push and it over the housing. Drill a 1/8" hole through the ABS pipe and the housing. Screw it into place. After you have the ABS screwed into place you need to seal it. Seal all the way around the pipe and the housing. You also need to seal around actuator for the hot air intake as well.

After you get all the joints lined up and marked, install it on the truck to so you know the cuts are correct. Before it's glued together you need to wipe all pieces with a mild paint thinner. Be careful the paint thinner will eat the pipe so don't soak it. Next, you will need to sand it down with a piece of gray scotch-brite so the paint will adhere on the plastic. Before you paint use the caulk to seal the joints so there's no air leaks.

The distributer cap should be sealed with the caulk as well. Just run a small bead on the inside of the cap. You will have to replace it just about every time you change your oil. If you don't you will get carbon build up on the terminals.

The tranny and oil dipsticks need to be sealed.

use the 4" tube to conect aircleaner to external pipe.
