You want to remove this cover. Two 10 millimeter bolts on this side, and one over on the passenger side. Remove those with a 10 millimeter socket and ratchet. Loosen the throttle body clamp with a flat blade screwdriver. Then you just kind of pull up and down on the whole ducting. There are tubes that go on the side. Once you pull it off the throttle body, you can twist a little bit and pull those tubes free.
There’s a clamp for the air filter. Pull that off, and there's two connectors. One is easy to see here. Press down on the tab and disconnect. You may press down the tab, use your screwdriver, and pry a little bit to help loosen it up. The connector's off. Then there's another connector. Press the tab and disconnect. The intake tube comes up and out.
Put your air intake back in place over here. The tab lines up there, and this clamp goes on. Just reach down and make sure nothing's getting pinched. Lock that down into place. Reconnect your mass airflow connection. Reconnect this connector, and put this back in here. The tube down here goes in there. Use a flat blade screwdriver to tighten up the clamp that holds it onto the throttle body. Put the throttle body cover back in place.
You just have to kind of move it around a little bit, and figure out where the bolt pull is. I'm actually cheating just looking through here. Once you're there, start it up, and then push this side down into place. Start my two bolts over here and then tighten them up.
Thanks for watching. Visit us at 1AAuto.com for quality auto parts, fast and free shipping, and the best customer service in the industry.
