2007-2012 Acura RDX Engine Air Filter Replacement (2007, 2008, 2009, 2010, 2011, 2012)

Introduction

There are many small particles in the air that can damage your engine if they enter it. A engine filter can stop these materials from entering and extend the life of an engine dramatically. Over time however, these particles can build up and make it difficult for the air to get through, so regular replacement is necessary.

Luckily, this is a car repair that is easy enough to do on your own, you should only need a 9mm socket, a new filter, and a little WD-40. All in all, it should be done in less than 10 minutes.

On the driver-side footwell, pull the latch to open the hood.
Make sure you leave time between driving and performing this fix. Working around the engine while it is still hot presents a burn risk!

Edit

Step 2

Lift up the second latch to fully open the hood.
This one is located right above the Acura logo on the front of the car.

Edit

Step 3

The airbox is directly behind the battery. Remove the four 9 mm bolts holding the airbox down.
If you ever had the bolts replaced, they may have a slightly different head diameter. If a 9 mm socket doesn't fit, use the appropriate size socket.

Edit

Step 4

Unscrew each of the bolts. Do not remove the bolts.
If the bolts are stuck, use some WD-40 or similar lubricant to help loosen them.

Edit

Step 5

Remove the air filter from the vehicle.
In many cases, air filters will have an arrow to show the direction they should go. This direction represents the airflow, for this particular car we want that facing upwards.
Do not fully remove the bolts.
