Okay, so we have to take this intake tube off, and to get to this hose clamp, we have to pop off this cover that's on top of the engine that just pops up. There's two points where it pops onto, so just kind of get them, and then you work it out straight from the back. Just like that. And see here, this is where it pops on here and here, and then these two tabs slide into the back. We're going to set this aside so it doesn't get broken.

All right, so before we take this intake tube off, we're going to pop this little PCV valve off. Just comes out like this, and place it aside. Okay, and the next thing we're going to disconnect from the air intake tube is this little hose clamp that's supporting the upper radiator hose. Just push down on it to unhook it. Then we're going to remove this hose clamp here at the throttle body. You can either use a flat-headed screw driver or an 8mm socket on a ratchet. All right, we're going to move to the other side here near the mass airflow sensor. Again, you can either use a flat-headed screw driver or 8mm socket. Now we're going to work this off the air box elbow just like that. Now you pull it off the throttle body. It's also got a little support here with these air resonators. Pull it up just like that, and then work it off the throttle body. Just kind of maneuver it out of the engine compartment, and we'll place this aside. We're going to lift the air box out.

It just sits on rubber mounts, so we're going to unclip the mass airflow meter. Carefully work that out. Just place that outside so you don't damage the connector. Then we're going to just kind of work this out off the rubber mounts, and it's just going to lift out of the engine compartment. We're going to put this aside too.

Now we're going to put the air box back into the vehicle. This just kind of pops on to the rubber mounts, and you just kind of have to feel it in there. So then, once you sort of find the holes that it pushes in to, it just kind of sits in there.

Okay, so once the air box is back in place, don't forget to reconnect your mass airflow meter. Make sure it goes on with a nice click. Just like that. All right, so we're going to put the air intake pipe back on. You've got to kind of fish this air resonator down into the engine bay. It's a little tricky because you got to get that long air resonator tube down the back of the intake of the engine. Just kind of float it into place. You can slide it on to the throttle body. It goes on to the throttle body, and then you just push it down right there onto the little mount. Come over here to the air intake of the air box. Work that over. Make sure that's seated. It's seated over here. Push the radiator hose back up into it. The clip that was holding it. Just like that. And don't forget to tighten these hose clamps. So again, you can either use a flat-headed screwdriver, or I'm going to use an 8mm socket. Just tighten these down, and you'll feel them start to get tight. Snug them down, and they're good. And again, the same thing over here at the air box. And one last thing you need to reconnect on this is that PCV valve that we popped out earlier.
