How to Install the Airaid SynthaMax Direct-Fit Replacement Air Filter on a 2018 GMC Sierra 1500


Today on our 2018 GMC Sierra 1500 we're going to be taking a look at and showing you how to install the AirAid SynthaMax direct fit replacement premium air filter. You can see the AirAid one is actually made from two synthetic polyurethane layers, which is not only going to flow better, it's going to catch more debris. What's great about the AirAid is it's going to last longer than the paper because you can actually wash this. The reason this AirAid is a great replacement, or even an upgrade, is because not only is it going to boost power, it's actually going to catch more debris, and it's going to be reusable, so it'll last longer.To begin your install, you're going to need to open up your hood and come over here to the air box. Right behind it we're going to have our mass airflow sensor. We're going to need to unhook the wire from the sensor.

To do that, there'll be a tab, you simply just push in and pull up. You can kind of just push that out of the way. We're then going to loosen up our clamp here. Now, you can either use a flathead or an eight millimeter socket to do that. You don't have to take it completely off, just loosen it enough to give it some wiggle room.Now, on the air box, we're going to have four fasteners just like this, one in each corner.

Now, you can either use a screwdriver or an eight millimeter to remove them. You're going to need to completely remove all four. Now what you can do is push the tubing off the air box lid like that. Kind of push it away. Then we can just lift up our air box lid.

There will be a little tab connected here just holding the wire in. You can just pull that off, and we can just set our lid to the side for now. Now we simply just lift out our old filter and set it off to the side.Now what we need to do is take our new filter and set it in the air box. Just make sure it's seated all the way around. We can take our lid, we're actually going to push our inlet tube over the housing there.

Then just push our lid down into place, making sure that we line up all the bolt holes. Now we can plug our mass airflow sensor back in, tighten up our clamp, and put our four bolts in, and we'll be good to go.That'll do it for our look at an installation of the AirAid SynthaMax direct fit replacement premium air filter for our 2018 GMC Sierra 1500.
