This is my first write-up so forgive me if I mess it up.For everything ,it came to $20.
First your going to need
1.One ten foot peice of 2in ABS. They only sell it in 10 foot peices so you'll have plenty do do another one.
2.Two 90s
3. A 3in hole saw
4.An extra intake tube from an XJ
5.1 tube of silicone
6.Hack saw
7.1 big hose clamp
Step 1 Drill a 3in hole in the firewall,right about here

And another 1 here in the back of the air box

You need a peice of 4in x5in peice of flat plastic to cover the factory inlet hole

I used wood screws to mount it.After you cover the hole then you need to silicone all the drain holes and around the cover you made.Like this.

Then you need to cut a peice of the ABS pipe to 4.5in and another at 10.5in.
I would give it at least 24hrs for silicone to cure.
Put 1 of the 90s and the 4.5in peice together then the other 90 on the opposite end .Then put the 10.5in peice into the 1 end of the 90 and dry fit it into the air box and fire wall to get your angle you need before you mount it.Next ,cut the bend off the extra intake hose and mount it to the fire wall like this.

Next you will silicone the ABS all together and let it cure.
Then you will mount the assembled ABS unit to the air box and fire wall.I used L brackets and wood screws.Silicone all screws.Then take the big hose clamp and secure the ABS to the extra intake hose.When your done it should look like this.

You will probably do a nicer job than I but it works just the same.I use my side mirrors as a gauge.If the water touches my mirrors I know to back out. I have had it that deep more than once and never had a problem. I hope this was a decent write-up job and you all understand me. Good luck to all that try this and THANK YOU for your time.

Did I miss how you seal the PVC pipe running from the air box to the flexible hose? It looks like air (or water) can be sucked in around that connection.

I should have taken a pic of that too.Sorry.

That's interesting... a cowl induction set-up...
What kind of room is there inside the cowl ??

Well done... I'd never need it... the deepest water I see is in the gutter...
