The Jeep Wrangler air filter ensures that clean air makes it's way into the Jeep's engine. It's job is to stop dirt and dust particles and allow clean air to pass through it. Naturally it will become dirty over time and will need to be replaced.

A dirty or clogged filter will restrict airflow to the engine. This can cause power and mpg loss in your Jeep. The operating manual states that the Jeep Wrangler air filter should be changed every 48,000 kilometers (30,000 miles). Dirty or dusty driving conditions can wear out the filter relatively quickly so it's important to inspect the filter often, especially if you are doing any off-roading.

Whether you are inspecting, cleaning or replacing your air filter the process to get into the air box is the same. These instructions will show you how to get into your Jeep's air box and replace the stock Jeep Wrangler air filter.

How to Replace the Stock Jeep Wrangler Air Filter

Step 1 - Locate the stock air box and pop the clips

Pop open the Jeep's hood and prop it up.  The factory air box is located in the lower left corner of the engine bay. There are four snap clips that hold the top of the box down in place. The clips are fixed to the bottom of the air box. You can pop these clips open without worrying about losing them.

Pull the clips outwards to pop them open.

Step 2 - Unbolt the air duct

There are two 10 mm bolts that keep the air intake assembly in place and will prevent you from opening the air box. They are located to the right of the stock air box just above the radiator.

Use the 10 mm socket to unbolt each bolt. Remove them and keep them in a safe place.

Step 3 - Remove the old air filter

You can now lift up the top of the air box to access the filter. Lift the top of the air box and remove the old air filter. At this point you can use a shop vac to vacuum any dirt that may be at the bottom of the air box.
