The Jeep Air Dam Dilemma

To Keep or Not to Keep?

Jeepers, like myself, often find themselves in a dilemma when it comes to certain modifications. One such modification is the removal of the Air Dam which has it's pros and cons,. The decision to keep or remove it ultimately depends on your priorities and preferences.

I removed mine during my front bumper install.

What is an Air Dam and What Does it Do?

An Air Dam is a plastic shield that is found under the front bumper of many vehicles, including Jeeps. Its primary function is to improve the vehicle's aerodynamics by reducing air drag. This, in turn, can lead to improved fuel efficiency and reduced wind noise.

Since the removal of mine, along with a lift and bigger tires, I have not seen a significant drop in my fuel efficiency. Most people who have Jeep's expect them to be noisy, especially with a soft top.

The Air Dam's Purpose According to the Internet

There are several claims and theories about the Air Dam's purpose floating around on the internet. Some of these include:

• Preventing water from entering the engine

• Providing additional engine cooling

• Reducing hood "flutter" at high speeds

• Protecting the engine from flying debris

• Maintaining fuel efficiency

Debunking the Myths and Misconceptions

While some of these claims may have a kernel of truth, many are exaggerated or misunderstood. For example, the Air Dam may help prevent some water from entering the engine, but it's not the only factor in keeping your engine safe from water damage.

The Wrangler Engineer's Take on the Air Dam

According to a Wrangler engineer, the Air Dam serves two primary purposes: reducing air drag and providing engine cooling. This aligns with the main functions of an Air Dam and helps to clarify some of the misconceptions surrounding it.

Pros:
Improved aerodynamics
Potential for better fuel efficiency
Engine cooling

Cons:
May not provide significant protection from water or debris
Hood "flutter" concerns at high speeds (although this may not be as significant as some believe)

The Hood Flutter Concern: Fact or Fiction?

While there have been concerns about hood "flutter" at high speeds, it's important to keep in mind that this issue may not be as significant as some believe. However, if you frequently drive at high speeds and are concerned about this issue there are upgraded hood latches you can purchase.

Personalizing Your Jeep: The Choice is Yours

Ultimately, the decision to keep or remove the Air Dam comes down to personal preference and priorities. If you prioritize fuel efficiency and aerodynamics, keeping the Air Dam may be the best choice for you. On the other hand, if you value a more rugged appearance or are less concerned about the Air Dam's benefits, removing it may be a viable option.

If you plan on taking your Jeep off-road the benefits of removal far out weigh the the benefits of keeping it on.
