How to Install the AFE Direct-fit Cold Air Intake System on a 2002 Toyota Tundra


All right, today on this 2002 Toyota Tundra, we are going to install part number AFE54-12262. To start off our install, we are going ahead and get underneath the hood, and we will go ahead and remove the trim cover over the throttle body. Next, there is going to be a bolt we have to remove from the AC line clamp. We will save that for re-installation later.Next, we need to remove the mass air flow sensor. First, we will go ahead and disconnect the wire harness, and then we will unscrew the screws for the sensor. We will set them aside in a safe place for now.

Next, we will go ahead and disconnect the vacuum hoses from the tube. The largest hose can be removed from the cylinder head with a valve cover head. We can go ahead and remove the rest of our hoses which are no longer connected, because new hoses are going to be provided.We will go ahead and also disconnect the wire harness that's clipped to it. Turning it at the correct angle, it will simply unsnap from the fitting that it is on. Now we will go ahead and loosen up the clamp at the throttle body, and un-clip the top half of the air box.

We will go ahead and remove the intake from the throttle body and we can go ahead and remove the whole assembly out of our way.All right, at this point, we can go ahead and start installing our new parts. First, we will install the seal trim on the housing itself. That simply just pushes into place. Friction holds it down. You want to make sure you push it firmly into place in the corners.

Next we will install the air filter adapter into the housing and secure with five screws. These will be the silver hex-head screws. Go ahead and remove the factory air filter as well.Now go ahead and take the new housing and place it on the bottom portion of the original equipment air box, and three or four factory clips will hold it in place. The fourth clip was with the housing we removed previously. Okay, now we will go ahead and turn our attention to the intake tubes.

There are three brass fittings in a tube. Two 5/16th fittings should be stacked on top of each other. The 3/16th fitting standing off to the side.At this point we can go ahead and reinstall the mass air flow meter into its new air tube. It come with a new gasket, we will install it first, and then the mass air sensor, and reinstall the screws. Now on both ends of the tube, we will go ahead and add the rubber couplings on each ends and the clamps. Then we will go ahead and install the tube, sliding the couplings over the throttle body and air filter adapter.At this point you want to leave the clamps loose. Now, the AC line clamp that we removed earlier we will go ahead and remove it completely, flip it over, and then re-install it. Then we will go ahead and fasten it to the intake tube with the original hardware. At this point we can go ahead and start installing the hoses, so we will go ahead and completely remove the original power steering valve hose, and replace it with the new one at this point.Using our 22-inch length of hose we are going to connect 1 inch of the power-steering valve which is below the intake and run the hose through the existing clip connecting the other end to the matching fitting on the new intake tube. Now in a kit, there will be 3 lengths of 5/16th hose. We will go ahead and connect all three together using the provided T.We will take one of the larger ends and plug it into the bar fitting that is in the air tube. Now the other end of our line, we will go ahead and disconnect it. It simply pulls off like the other lines and we will connect it. Next, we will work with the short tube that goes to the vent on the engine. Now when we put the two together, you will see that they don't match. What we are going to do is go ahead and use the small length of the original line that was on there which makes a snug fit with the new line and we will use that as basically like a union.So we will cut a couple inches off the original line, push it on to our new line and then put it back into the fitting in the vent on the engine. The last hose that we will connect will be our smallest hose. We will go ahead and disconnect it. Valve cup to the valve cover vent. Everything else you reuse the existing clip as well to keep everything together, and now go to the smaller brass fitting on the air tube.Now I'll go ahead and slip the air filter into place. We can go ahead and reconnect the electrical to the mass air sensor. Okay, at this point all of our connections are made, so we will go ahead and tighten down all the clamps. Next we will go ahead and reinstall the throttle body trim. We will also take a moment to zip tie the hoses to makes sure everything is nice and out of the way and secure. Okay and with that, that will finish it for our install part number AFE54-12262 from AFE on our 2002 Toyota Tundra. .
