Justin: The JLT Cold Air, specific to the 2018 GT, will be a tune-required option, boosting one of the largest mass air flow housings available for the Gen 3 Coyote at a whopping 120 millimeters. JLT does utilize a rotomolded plastic construction for the tube itself, in addition to the heat shield and fresh air ducts, before topping everything off with their massive 5-inch S&B high flow reasonable filter. Price point for the JLT will end right around 350 bucks, and the install will get a relatively simple one and three wrenches on the difficulty meter from me, with a detailed walkthrough to come later in the video. First things first, let's talk about the stuff you, guys, want to hear. And that is dyno numbers. Now, we established a baseline run with our manual 2018 GT first, we then got to work installing the JLT Cold Air, offloading the necessary tune. We reran the car the same day, and here are the results. Our baseline numbers, using our manual 2018 Mustang GT gave us 437 horsepower and 401-pound feet of torque to the rear wheels.With that JLT installed and the necessary tune uploaded, the car is now making 461 horsepower and 406-pound feet of torque to the rear wheels. Now, that is good for a peak gain of 24 horsepower over our baseline numbers and gains of as much as 24 horsepower and 13-pound feet of torque under the curve. Now, JLT was actually one of the first companies to market with their 2018, specific Cold Air, as the small tweaks and lower hoodline of the car did ever so slightly change the fitment. Now, JLT actually claims they borrowed some of the inspiration from their GT 350 kit, along with computer redesigning a new system that fit the redesigned S554 2018. But with that said, let's break down some of the stats for the new JLT, and on the surface, guys, you're looking at their tried and true Coyote recipe here. And that is the one-piece plastic intake tube with the integrated mass air flow housing. And on the topic of that mass air flow housing, again, guys, you're looking at the largest currently in the category at a massive 120-millimeter opening here. Now, that's actually up 10 millimeters over their existing '15 kits to '17 kits.So, for guys out there just saying, "They just rebranded their original S550 intake," that's simply not the case. Now, the theory here is the bigger the opening, the more air you can attempt to stuff into that really great performing 2018 intake manifold. But, again, because you are looking at such an upgrade over the factory size, the use of a custom tune is absolutely required here. Now, topping off that massive 120-millimeter opening on the intake tube is the equally large S&B 5 by 7 filter with the power stack filtered ends. Now, JLT also likes to point out that they do build in a bell mouth and radius the end of the tube to help get a nice smooth flow or signal over that factory mass airflow sensor, which is something your tuner will be very happy to know, and will help ultimately dial in that tune a little better. Now, that filter is oiled, it can be washed, reused, reoiled as needed. And finally, guys, JLT does throw a one-year warranty at this thing in case you run into any issues. But let's get into the installation here, guys, and honestly, Cold Airs will be one of your easier days in the driveway or garage even for the most novice mechanics out there. So, we're sticking with a one out of three wrenches on the difficulty meter, and maybe 30 minutes to an hour of your time, depending on how fast you like to work. And to give you a better idea of what you're in for, here is a detailed walkthrough in addition to a tool breakdown.Man: For this installation, you're going to need a few simple tools, the flathead screwdriver, a Phillips head screwdriver, T20 Torx bit, a short extension, an impact gun or ratchet, a 10-millimeter socket, a 15-millimeter socket, and a pair of pliers. To begin this, we're going to go ahead and remove the tower strut brace if your car is equipped with it and our engine cover. After that, we're going to go ahead and remove our factory intake, and it's just a few bolts, it's a 10 millimeter down here on the inner fender well, few vacuum lines, and a hose clamp. Let's get started. Using a 15-millimeter socket, we're going to go ahead and remove the two bolts on each side that hold down our strut tower brace. I'm using an impact gun, you can also use a ratchet. Now, over here, on our passenger side, we're going to go ahead and have to remove our battery cover. And that's just one or two clips, and it pops up and out of the way. Now, that our hardware is removed, we're going to go ahead and lift our strut tower brace up and out of the way, and just set it off to the side, we're going to reinstall this later.Next, we're going to come in here and take off our engine cover. We're going to start by removing these little caps that cover up the bolts and then the 10-millimeter nuts that are underneath. Now, that the caps are removed, we go ahead and remove the 10-millimeter retaining nuts. Now, just put it off to the side, we'll be reinstalling this later. We're gonna be taking our factory cold air unit out as a whole assembly, and it's very easy. We're gonna go ahead and unplug our mass air flow sensor, and we're going to disconnect a couple lines that are connected to the tube and loosen up our clamp, and a one single 10-millimeter bolt here on our wheel well. Using a pair of pliers, just go ahead and remove the sound tube off your intake tube. Next, we're going to remove our PVC line, and these are very simple to take off, you just pull this little clip back, and then it unlatches it. By pushing in on this black clip, we just slide our vacuum line out, tuck it out of the way. And with a Phillips head screwdriver, go ahead and loosen the clamp on your throttle body. Now, with your 10-millimeter socket, go ahead and remove the bolt retaining it to the inner wheel well.Now, that everything is disconnected, we're going to go ahead and remove the hook from our throttle body and slide the whole unit out as a single piece. As you can see with our factory intake and our new JLT intake, you notice that the new JLT intake tube is very smooth and free-flowing, it doesn't have the bellows, like the factory one. This is where your horsepower comes from. We're going to install a new JLT intake, but first, we're gonna remove our factory mass air flow sensor from our factory air tube. Using a T20 Torx, go ahead and remove the factory mass air flow sensor from your intake. Now with your factory mass air flow sensor, it's going to have an O-ring around it that was using your factory intake. We're going to go ahead and slide that off because we're going to use a new rubber gasket that comes with our new intake system. We're going to replace it with this gasket. Now, using the new hardware that comes with your kit, this is gonna be a Phillips head screw, makes it a little easier, not everyone has Torx bits. Now, go ahead and slide your mass air flow sensor inside your new intake tube, and secure it down.Now, that that's together, we're gonna go ahead and get the rest of our intake installed in our 2018 Mustang GT. We're going to begin the installation of our intake by installing the new airbox that comes with it. Slide it down into place. Once the new airbox is in place, go ahead and secure it with the factory hardware. Now, with our new intake, we get the option to use or not use our factory sound tube that goes through the firewall. If you would like to use this to retain the factory sound tube, what you're going to need to do is measure down just a few inches from your PCV line, and you're going to drill a hole there and install the fitting that comes with it. Now, for this video, we are not going to use that. Next, we're going to go ahead and install our reducer onto our air intake tube, followed by our air filter. Once this is all assembled, we can go ahead and install it into the vehicle. We'll put our clamp over the end of our filter, and then go ahead and slide our filter onto the air of the intake tube. Now, that our air filter and our reducing coupler is on our intake tube, we're gonna go ahead and tighten down the clamps. Then, we're gonna go ahead and install it on our vehicle.Now, with your intake assembled, slide the clamp over the coupling, and the coupling over the throttle body inside the new intake into place. Then, tighten up the clamp. Now, we're almost done with the installation of our intake, we only have a few parts left here. Just gotta go ahead, and we make our connections to our mass air flow sensor, our PVC, and our vacuum line. And we just have one little heat shield that goes over here, and will be complete. Go ahead and slide your foam heat shield down over the intake tube, into the airbox. This will keep any engine heat away from the air filter, making sure that your cold air stays cold. Follow that up with reconnecting your mass airflow sensor, slide your PCV line in until you hear the click, and lastly, install your vacuum line. Now, that your intake is installed, you can go ahead and put your engine cover and your strut tower brace back inside. And you're gonna want to get your tune installed before you go ahead and drive this. This intake does require a tune. Once your tune is installed, you go ahead and enjoy your new JLT Cold Air Intake for the 2018 Ford Mustang GT. And for more parts and videos like these, make sure you visit us at americanmuscle.com.
