Talking AEV Snorkel - Thinking of plugging airbox

I got the 2nd Gen AEV snorkel for my 2012 jkr. Here is a advertising picture.


Theinstructions say to keep the drain holes in the bottom of the airbox unless your doing some serious stuff. I'm thinking of plugging it up to be on the safer side. The design of the air ram should prevent almost all water from rain from entering.


WILL I REGRET PLUGGING THE HOLES?
I'm in the process of reading as may threads to see if the plug will create any issues. Found only one so far, and that seems to be a case of a kid hitting it hard with a hose. Snorkel owners.....Don't block your holes in the air box !!!!!! (I got away with it) . If you have any experience with sealing the box up, and how much water will slowly collect potentially, I would love to hear it. I'm assuming small amounts of water would evaporate with the engine heat and not be a huge deal?

DUCKBILL DRAIN IDEA
I want to put a duckbill one way drain valve in. Basically like this dude did. AirBox Drain

I cannot seem to find any for about 10-20 bucks. I found a few for $40ish but that is a bit too much for my worries. Anyone know a cheap place to find one of these drains.

RUGGED RIDGE WEEP VALVE IDEA
The RR snorkel uses a clear tube that's maybe 3/4" that connects to the lowest point of the snorkel. It has a clamp that you can undo to release any water that has built up. Being that it's clear you can easily see if it needs to be drained. So I was basically thinking of perhaps fashioning something like that.

ADVANTAGES OF TOTALLY SEALING AIR-BOX DRAIN HOLES (Perhaps)
I was thinking about how if you have a tiny hole in a drinking straw. Like for a coke it will basically make it were it won't work. I'm wondering if a fully sealed box would actually get better air flow/density/cool air vs keeping the drain holes in?

BREATHER HOSES - I already extended my breather hoses and made a thread about it. I'm not planning on running them to the airbox. Extend Breather Hoses with Pictures - Axle & Transfer Case

SCREWS VS RIVETS- There are a few parts were AEV wants you to use rivets. I'm thinking of using stainless bolts instead.

Ive sealed my airbox with a river raider expedition snorkel. On a couple of occasions ive found water in my airbox. A surprising amount on one of the occasions. The only thing I can figure is that snow is making its way into the system, sitting on the air filter until it melts, and then pooling in the airbox. This wouldnt really be an issue the way that AEV maintains the stock flow direction through the airbox. The river raider setup reverses it (the engine side of the intake is on the bottom of the airbox) and is a bit more of a concern in my opinion. I wouldnt be too worried about sealing it for your setup, just check it from time to time for any water build up. Even if a small amount of water gets in there, its not going to make its way up through the filter easily. As for the duck bills, I looked into them too. They are popular with jet skiers. Most of the people I found talking about them were complaining that they leaked after some time. There is a ball valve that many recommend working better where the ball basically floats to open a valve. When all was said and done, I decided not to bother with a drain valve. If you end up sealing it, use a high quality silicone. Momentive RTV103 works well.

Can get a check valve or 1 way valve and a short piece of hose and use it to let drainage and keep water from getting in

So based on that, seal it up tight with extra silicone and don't add any valves if you plan to do that

Talking Thanks guys

Thanks for the replies guys. I'm going to seal it up. I read an aussie thread were the guy said a duck bill drain failed on him. I never plan on getting deep enough to submerge the airbox, but better safe than sorry. That River Raider snorkel is awesome spieg. It's good to hear from someone who took the plunge and sealed there air box. Thanks Txrdstr, for some other ideas/terms to look into . I can always put a valve in later if need be, and those could come in handy.

INSTALL SO FAR
My airbox had a pretty good coating of mud film in there. I have washed it out the best I can. I think I might give it a quick cleaning with some acetone so the silicon will stick as good as possible. Most of the factory drain holes are a good 1/2" wide. I tightly coiled/spiraled up some bailing wire to drop on top of the holes. That will hopefully help hold the seal. I got my silicon from Home Depot. It's clear and says its for automotive stuff. Now that I already have it I guess I'll take a chance on it.

I've got the hole cut. The cutting wasn't too bad using an angle grinder cut off wheel. Took maybe 30min. I did go about 1/4" outside the lines by one of the cut holes, but thankfully the plate covers that up. The major pain was using a small touch up paint brush to clean up afterwards. Went OCD on that big time.

I ended up getting a rivet tool. It was only $10, and I can drill them out if I mess up.

The instructions are really good. I went a bit astray with them. It has you cutting the hole first. I did a test fit first. Then I put painters tape to the quarter panel on the outer edges were the snorkel comes out. With the hood closed then I could tell that the template was dead on.

QUESTION-So you bolt on 3 attachment braces to the snorkel tube. They give you a washer and a slightly smaller locking washer for each bolt. I put the braces directly onto the snorkel (and it's embedded nuts). Then I put the standard washer against the brace. Locking washer on top of that. Pretty sure that's how it's supposed to go? VS snorkels embedded nut,standard washer, brace, locking washer on the outside.

Seal up all the holes in the stock airbox. You won't have any issues by sealing them! Don't forget your Transmission breather tube even on the 6spd.
