To seal the airbox or not?

[ShooterMcGavin]

I took my airbox out today to look at the holes I have heard people talk about. Looking at them, I realized that they are drain holes in case water gets into the airbox. I sealed up the tiny holes for the clips that hold the air filter. Should the other 3 holes be sealed or left open to drain?

Ideally, there should be a one-way valve.

Those holes usually won't suck in water. Stock air box works great. It's when you submerge the motor than it becomes an issue.

OK. I was just thinking of a cheap way to possibly raise the water crossing level of the truck. No, I don't really need to do that any time soon. I have had water splashing up over the hood on a river crossing before but that is very unusual for me.

If you install a snorkel would it be prudent to seal those holes?

I'm wondering the same thing.

The drain holes are not a problem unless you are really going to let the stock air box be submerged. Then yes you want to seal the entire intake as good as you can. But again at this point water will be coming in the cab, all electronics in motor get soaked and your diffs will fill with water.

The stock intake box is great for low water crossing and fast water crossing. Open intake I have sucked water in just hitting a puddle.

I think I will leave the drain holes as they are now, unless I get a snorkel and feeling like getting crazy. Until then, I did seal up the tiny holes where the clips are held into the airbox.

Ive been super lazy and have not installed my stock air box. I have sucked water in twice on the road with our heavy rains last two years. I now avoid water like the plague!! Or just go very very slow. Which you should do anyways.

Go slow through puddles... always, or just when using an exposed/cone filter?

With open cone filter. With stock air box your good to water ski those puddles!!
