well im going to put a snorkel mast on my jeep soon and i need to know. how do you completey seal your air intake box? do you use a type of glue or something. if anyone can plz give me type of glue and also where exactly i need to close it up! thank you!

 

How 'bout duct tape.. covered with flex seal or truck bed liner spray?

 

have you tried that at all? i know people use something but i dont know what! dont want to try it if no one has!

 

I used the all weather silicone the stuff that doesnt shrink or crack and rtv

 

That may seal it..but it won't do **** for water proofing it.

 

I used silicone and for the front where the big hole is i used an outlet cover and siliconed it real well

 

for the rectangle hole...
i used a decal squeegie cut to size (flexible yet tough plastic)

then i used heavy duty silicone to seal the edges. also theres two drain hole inside the bottom of the box. some leave them open to let water drain but i have a rediculously sealed snorkle system.

 

x2 I dont wanna have that water get into anything!

 

For my cowl intake I just used duct tape and hot glue

 

I beg to differ. Google flex seal.. the guy sprayed it on a screen door and used it for the bottom of his boat. Truck bed liner not waterproof?? What planet are you on? Duct tape is probably not waterproof for long, especially if submerged.. but it will seal up his airbox, and with the rubber stuff sprayed on top of it, it will be waterproof.

 

Okay I see you're point. But long run / being in water from any mount (a woke) it won't hold up anywhere as well as silicone.

 

How about we suggest using a product meant to do the job...esp when its inexpensive?

Silicon works really well, and is meant to seal. Duct tape and bedliner....not so much...

 

Lol good call the only down side ive heard to using the wrong kind of silicone/rtv if it get into your exhaust some how, god forbid, it can compeletly mess up your O2 sensors.

 

Alot of things can be bad if run through the motor.

I doubt bedliner is a great fuel substitute...

 

use a heavy duty silicone... its worked for me. ive had it to the windshield in water, and it was still running.
