Kia Universal Air Filter

Replacing your Kia's air filter is a straightforward maintenance task that can improve engine performance and longevity. Here's how to do it:

1、Locate the Air Filter Box: Open your hood. The air filter box is a rectangular plastic box, usually on the driver's side of the engine bay (e.g., Kia Rio, Forte, Optima). In some models like the Sorento, it's clearly visible with air intake pipes.

2、Disconnect MAF Sensor (If Applicable): If your model has a Mass Air Flow (MAF) sensor attached to the air filter box, gently disconnect its electrical plug by pressing the locking tab.

3、Release Air Intake Connection: Loosen the circular clip or hose clamp connecting the air intake tube to the air filter box using a 10mm socket, Phillips screwdriver, or by turning the screw counter-clockwise. Then, carefully pull the tube away.

4、Open the Air Filter Box: Release the retaining clips or bolts holding the air filter box together. Many Kia models have several clips around the edges; use your fingers or a flat-head screwdriver to pry them open. If it's bolts, use the appropriate tool to remove them.

5、Lift the Cover & Remove Old Filter: Carefully lift the air filter box cover and set it aside. Pull out the old air filter. Check it for excessive dirt and debris—a clear sign it needs replacing.

6、Clean the Box: Use a clean rag to wipe down the inside of the air filter box, removing any accumulated dust or dirt.

7、Install New Filter: Take your new air filter and ensure it's the correct size and type. Insert it into the box, making sure it's properly seated. An arrow on the filter often indicates the airflow direction, usually towards the engine.

8、Reassemble Everything: Place the air filter box cover back on and secure it with the clips or bolts. Reattach the air intake tube and tighten its clip or clamp. Finally, plug the MAF sensor back in if you disconnected it.

9、Close the Hood: Close your vehicle's hood securely.
