Missing air dam, what to do

Long story short my air dam is wrecked and pulled off. What should I do? They are ugly but should I be looking for some kind of skid up there or other option.
Thanks

The air dam is crap anyway.


Replace your bumper and get the matching skid plate.

The air dam helps keep the hood from fluttering, if that does not bother you I would not worry about it. If it does post up in the wanted threads and you might find someone close with one laying around they are not using. Most people that lift their jeeps remove them.

If you learned something new today, you had a good day.

If you have a Rubicon, then I would lean towards a skid since the electronic sway bar motor is vunerable up there, otherwise you can run without it without worries.

I've removed the hood spring, and that also can eliminate/reduce the hood flutter.

The air dam is not a skid plate and offers no protection.

Very very interesting!

Since I ripped mine off wheeling I noticed way more hood wobble. Never connected the two. I like the look without it. Cheapest mod yet! I tossed mine in the garbage lol.

Another thing the air dam does is lower the pressure in the engine bay, which promotes air flow through the radiator.

I removed the plastic air dam, and installed a steel skid plate.
In the second picture, you can see how it protects the e-disco.

Every vehicle has an air dam or equivalent right under the front bumper - usually a plastic piece that goes from one side of the engine compartment to the other. It acts to increase the air velocity going below the engine compartment, thus decreasing the pressure (Bernoulli's Principle) - to reduce the air flow up into the engine compartment from the road. In the absence of the air dam, air travels more slowly through the radiator (restriction) than it does underneath the vehicle and the air fills the compartment from below. Then your hood has a tendency to wobble.

Ronjenx is right - an aftermarket skid would alleviate the problem of hood flutter.

1. just rotate the e-disco motor up and rebolt in place.
2. Use quick disconnect sway bar links.
3. The air dam provides no protection
4. Hood flutter....replace hood straps with new ones from dealer ($15), they had a recall on earlier hood straps that were not strong enough. I replaced mine and no more hood flutter, despite no air dam underneath.

you are correct it doesn't even come close as a skid plate... I worded that totally wrong. I meant to say when you get a new bumper get the matching skid plate which then protects you..... maybe I was writing it with response to the X2 reply right above me... none the less poor writing on my part..... good catch

This is the set up I have. Works great.
