This is what I was thinking about doing. Isnt the factory air box fairly restrictive as well? So that would get better airflow to the engine.

 

From what I understand, no, they are not restrictive at all. Thats why cold air, or ram air intakes are such a waste of money.

 

Thats correct but,This is for engine protection not cold air intake.

 

How did you dome to this understanding?

I know the purpose of this snorkel. I was just wondering if the factory airbox was done away with would you get better airflow?

 

You get better air flow with this setup.It has a great induction roar at W.O.T.

 

Isn't the angle of the hole in the firewall for the intake tube susceptible to suck in water if it gets over the hood? Could you block it somehow with a filter or something similar?

 

actually in the long run it really isnt, by doing it the way i said you can remove the stock air box completely, you buy different filters instead of the flat ones and also you arent as acceptible to flooding the engine therefore better for the jeep

 

I understand what a snorke's purpose is. And I wasn't knocking its purpose whatsoever.

Notice I was talking about cold air and ram air intakes?

By reading flow charts on the 4.0 motor and its intake system, including the factory air cleaner setup. If you search you can find the information.

Just wondering here, do you have any figures to back this up? A dyno sheet of before and after, or are you just assuming you get better air flow because you can now hear the intake?

 

Anyone??

 

This design isn't meant for driving in water over the hood. You are looking for a more traditional snorkel kit.

Notice how the OP said he uses his mirrors as a gauge? If it touches the bottom of the mirrors, he backs out...

 

Yea I understand that, but I'm just wondering about even just splashing over the hood and heavy rain that can just seep in through the vent under the windshield wiper? Is the angle steep enough so that no water gets in there?

 

I'd think you pretty much run the same risk as a factory intake. You may get some splashes in, but it'd be the same as if you were driving in heavy rain. Your filter may get damp, but it shouldn't be super bad unless submerged.

 

just so i understand this there is no air filter in the air box only a cone style filter in the cowl?

 

I think you are correct but I haven't been able to see the pics.

 

Water is much denser than air. In order for the intake to suck in enough water to cause problems, the intake would need to be submerged. The cowl area would take many gallons to fill up, water splashing in or rain wont be enough to fill it up. Also being that the factory air box is the lowest point and fairly large any water would pool in the bottom of that before getting sucked the engine.

It should work fine with the factory filter or a cone filter. Theres really no reason to bother with a cone filter though, just a waste of money.
