LOST JEEPS :: View topic - What good is this part?

Is this part important?

Will I get better gas milage with it (better air
flow to intake), or is it just going to be a waste of my time and money to
put one on?

It's just like your splean, no one knows what it does or what its for :-)r

But if it ruptures you die. :shock:

It probably just seals the intake between the hood and the intake. Keeps heat from the engine from getting into the intake, but I would say it doesnt keep water out of the intake.

That little plastic thing that is mounted infront of the intake does keep water from getting into the intake though.

The spleen disposes of old red blood cells.

Right now at 18degrees F I don't think we need to worry bout engine heat in the Motor City.

Okay, open the hood, look up at the top, forward passenger side corner, you'll see a little spongy piece attached to the hood that closes down over the air intake when the hood is closed. I think it's called an air deflector something-or-other. Mine is missing. Is this part important? What does it do? Does it increase airflow by directing air into the intake instead of letting it leak over into the engine bay? Will I get better gas milage with it (better air flow to intake), or is it just going to be a waste of my time and money to put one on? Any comments would be appreciated. Thanks.

Couldn't say for sure but, I think it's there to keep water from getting into the intake but, unless the water is on the hood you wouldn't have to worry about it. Rain would be on the hood though so you might want to look into getting one.

I think I'll get one anyway. If it's for water or air it has to be good for something. The nimrod mech at the stealership told me I don't need it and it doesn't do anything so I asked him why they even put it on then and he went dumb on me.

Any increase in MPG would not be caused by that little piece of rubber / foam thing.

Since the top of the airbox is hard plastic and this section of hood looks to be bare metal, I'd say it's just to prevent rubbing/vibration of the hood or air box lid. Doesn't look like it has anything to do with intake of any sort.

Thanks Jeepjeepster for the pic and explaination. I think you're right. It probably keeps the engine heat from entering the intake and maybe also it directs the cool outside air directly into the intake so that it doesn't get misdirected over the engine. I'm thinking that this air flow direction must increase performance in some way even if it is minor. I bought one from the stealership and am picking it up today and installing it. Trying to get things back to stock after buying used. Thanks again.

With the amount of cost and material optimizing in vehicles today, I doubt Chrysler would add a part if it didn't serve at least some mildly important purpose.

That little plastic thing that is mounted infront of the intake does keep water from getting into the intake though. What he said. The foam seems to make a barrier so only cold-ish outside air gets sucked in, not the hot engine bay air. You could probably fashion something similar yourself if you felt up to it. Or junkyard perhaps?

theshoestore, I bought it for $10 at the stealership. It has little push-in plastic screws that line up with the holes, etc. 10 second install. A lot easier than making one and since its so cheap its better to just get a new one. I also replaced my engine bay hood liner because it was ripped to shreads. By the way, it increased my gas consumption by .01 mpg more but the weight increase took back the difference. haha Maybe the engine will run better with the seal illiminating the hot engine bay air. Remains to be seen. It's there for a reason.
