Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!

Open the hood. We have to pull the release inside the car. It's just inside. Right around your left knee on the driver's side. I need to release the secondary, or safety release. Just kind of feel around for it. This one is right here. Squeeze up.

Mass airflow meter is located here at the back of the air box. To remove it, start by unplugging it, push down on the connector to unlock it, and then wiggle the connector off. Use a Phillips head screwdriver to remove the two screws. Grab the screw, and put it aside so I don't lose it. Do the same for the other one. This should lift right out of the intake tube.

This is the original mass airflow meter from our car, and the brand new one from 1AAuto.com. It has the same style connector and the same style mounting holes. This should fit and work great in our vehicle.

So you can only install it one way because the screw holes aren't going to line up. So line them up like that. Just push it in, and it will go past the rubber O-ring. Use your magnet if you don't have a magnetic screwdriver. Get that in place. These are just self-tapping screws. As soon as I feel them get tight, I'm just going to stop. That's nice and tight. Reconnect the plug. The job is complete.
