So after going 4 wheeling and hitting puddles 1 to 2 feet deep at about 15 mph I noticed that I had gotten water into my stock air box.

Now it wasn't much and drained through at the bottom but I did see evidence of it hitting my filter.

On my previous car I had a Cold Air Intake where the filter sat about 4 inchs off the ground. For some slight added protection I put a Hydroshield/Dry charger over the filter to help repel water. It did repel water for the most part. But after a certain point it becomes saturated.

So I measured the stock air box inlet and found a Drycharger thats fits perfect.





Here it is completely tucked down in front.





Now the question is how well will this work. Now I don't expect it to keep out a river of water nor anywhere near the protection of a snorkel. But if it prevents the water splashing in from puddle jumping then I'll be happy.

K&N part number is RB-0900DK

 

Hmmmmmmmmmm. I would say unless you want to replace your engine - - SLOW DOWN. That depth of water at 15 mph is a recipe for trouble. Not to mention that fact you're sucking air through a bag now.

 

Thanks for keeping us posted on this! I understand what your talking about. For many of us deep water crossings are something to be avoided. We know the damage that can occur when water is compressed by the engine!
Still, those quick splashes in the shallows take on way to much water than they should. I'm convinced it's the water rushing off the hood, down into the fender and into the box. It's not enough water to hydro lock a motor, because even if it get's past the filter, there's soooooo much more air than liquid (thus compression without damage). I AM NOT saying damage can't occur, just that the application of the pre-cleaner is a good idea to stop the splash effect on the filter.
Keep us posted on how it works!
