      Video Review & Installation

      Justin: The K&N Blackhawk intake here will be a great choice for the 2018 and newer Mustang GT owners out there who are looking for a no-tune required intake that will deliver a very stealthy all black appearance and want to go with one of the most trusted names in the industry like K&N. Now, the Blackhawk will come with everything needed for the installation including the dry synthetic filter along with the heat shield all for right around that mid $300 price point. Since the installation will not require any cutting, drilling, permanent modification, nothing crazy, we're going to call it a one out of three wrenches on the difficulty meter here, about an hour or so to complete from start to finish, but you hang until the end of the video, we'll show you how it's done.So K&N is one of those household names in the automotive aftermarket and one that has been around doing their thing for a very long time. And the Blackhawk here has been a popular intake choice for different generations in the past and now is available for the Gen 3 Coyote again found in the 2018 and newer Mustang GT. Now, as the name implies, the Blackhawk is all about murdering out or blacking out 99% of the intake including your synthetic dry filter, and even smaller things like the included clamps. The only exception here with this intake is this little plaque on the actual mandrel bent aluminum tube, which has been milled and the K&N logo is shining bright but everything else is done up in all black.But breaking things down even further, you're going to find the Blackhawk like K&N's other intake offerings currently for the new GT will feature that open element design which is going to have its pros along with some cons. The pros here will no doubt be the dramatic increase in noise coming from under the hood under hard acceleration, along with a much cooler look compared to a more traditional sealed enclosure. Now, the one big drawback with something like this is that you're not fully isolating the filter from any hot possible engine bay air from entering the intake itself, and that's where a sealed enclosure or airbox will get the nod.But what does it all mean when it comes time to talk about power? Well, K&N claims 9 horsepower, 23 pound-feet of torque with the Blackhawk installed, and that is without the use of a tune. And if I were to guess, that would probably be crank numbers and not tire numbers because the reality is a no-tune required intake like this will typically yield high single digit gains to the tire at best without the use of a tune which again, this intake does not require. It can run one with it if you'd like but it's certainly not a necessity. Now, that's not to say there aren't other benefits here with the K&N intake installed including the small bump in power, along with a little bit more throttle response and the much cooler look, but I don't want you guys thinking an aftermarket intake like this is going to set the world on fire in terms of gains to the tire.But aside from the benefits and the look, the Blackhawk here will definitely deliver some really nice components including that black aluminum intake tube we've already talked about in addition to the filter and airbox. Now, as we mentioned earlier guys, this intake is going to be a little bit unique because unlike the traditional oiled cotton gauze filter that K&N typically includes with their systems, the Blackhawk here is going to go a different route. Instead, they're going to utilize a dry synthetic material, so still going to be washable, still going to be reusable, but it won't need that extra step of re-oiling before the install, which some owners might see as a benefit. Now, in regards to actually cleaning the filter itself, K&N states this thing can go up to 100,000 miles before it needs a deep cleaning but depending on your area, you might want to consider cleaning it a little bit more often.Last but not least, guys, K&N does kick in all of your hardware, your couplers, your clamps, things like that needed for the installation, in addition to your molded heat shield here, which as you can see, does tap into your factory cold air system or ducting, I should say, from the front of the car to help get all that fresh cool dense air on to that synthetic filter as possible. And to help seal out any possible hot engine bay air, K&N did include this kind of weatherstripping to be topped off on that airbox to seal to the underside of the hood again in an attempt to block out all that hot engine bay air because this is not a sealed enclosure. But as promised, let's get into the installation with the Blackhawk on our 2018 GT. So without further ado, here is that detailed walk-through along with a quick tool breakdown.Man: Tools required for this job: diagonal cutters, needle nose pliers, push pin removal tool, three and a half millimeter Allen key, 4-millimeter Allen key, 16-millimeter wrench, 3/8-inch drive, quarter-inch drive, extension, T20 Torx bit, 7-millimeter socket, 8-millimeter socket, 10-millimeter socket, and a 15-millimeter socket, optional is an impact. Today I'm going to show you how to install this K&N Blackhawk cold air intake. All right, we're going to start off by popping the hood. We're going to first start off by removing our battery cover and disconnecting our negative side of our battery. All right. Now, to remove our factory engine cover, we do have to move our factory strut tower brace, it's a 15-millimeter deep socket.All right. Now, with the strut tower brace removed, we can remove our two 10-millimeter nuts. There should be two covers on here, ours are missing. So with this, there's going to be two pressure fittings in the front, two in the back. And just set this off to the side. All right. Now underneath the hood, we're going to be removing some of the factory connections like the mass airflow sensor here, just a little red tab underneath that plug, pull back, pull it out, set that to the side. Now this is your sound tube that emits that exhaust note inside the cabin. We are going to use a pair of needle nose pliers and bring this clamp back until it locks into place like that. Now we can pull that off, maybe use a pair of pliers or a flathead screwdriver.All right. So what we're going to do with this vacuum line is twist it towards us so we can expose that whole tab back there. With fingernails on both sides lift up on it, just put that back in its place so we don't drop that. And we're going to move on to this. This is your PCV over here. It's going to be underneath that one right there [inaudible 00:07:26] things up. Now with that out of the way and that, we can start working on our clamps and the bolts to secure the airbox itself. All right, now we're going to disconnect our sound tube right here, just pull that right off. And then with a 10-millimeter socket, we're going to be removing the single bolt holding our airbox in. All right now I'm using a 7-millimeter socket for my hose clamp on the airbox. Now with this, we're just going to move it to the side. It clicks like that. You can pull it off. All right, now our airbox is ready to come out as one. So what I'm going to do is lift up on this, pull it away from the body there and remove it.All right. So now I have all the parts for our new cold air intake laid out on the table. And this little weather-stripping here came in one long strip. I cut this to 34 inches and this to 9 inches as it says in the instructions, and I'll show you how it goes on. We're going to start at the bottom edge over here and just slip it on past those grooves. And now for the turns, you can cut it. We are going to make the turn because it is pretty flexible. And I'm just going to go back around, make sure it is seated evenly all along. Going to move on to our nine-inch section. Now we're going to take the part that mounts your air filter inside this box. There are threaded inserts. We're going to use the supplied hardware and get them started here. These are 4-millimeter Allen heads. All right. Now, we're going to install our fresh air duct, and you'll see that there is a little cutout here, we're just going to need to position that into the grooves here. Now, this is flexible so you can work it into place.Now, we're going to install this in the car. All right. Now we're going to be putting our new heat shield and air duct in. We're going to make sure our mass airflow sensor is out of the way and we're going to sneak our air duct into place and that goes forward into the grille here and sits over top. We're also going to make sure our little nutsert here is in place, and we are going to be reusing our factory hardware which was that 10-millimeter bolt. Slip that in. Restart that by hand and tighten that up. All right. I'm just going to check again, make sure my fresh air duct is in its spot. It is. All right now we're going to get our air filter in there, but first, we have to switch over our mass airflow sensor from our old stock intake airbox to our new elbow.All right. Now using a T20 Torx bit, we're going to be removing our factory mass airflow sensor. We're going to set this off to the side. Make sure your gasket stays in place like that. Set our factory airbox is out of the way as well. All right. Now with the new intake tube in front of us, we are going to set our mass airflow sensor in place, gasket into place as well. Now, there is new hardware. This Allen key head screw. All right. That's ready to install in the car.All right. Now we're going to be installing our hose coupler to our airbox. This is on by an 8-millimeter hose clamp. I'm just going to set it up all the way against that box. And then always put your hose clamps in a nice easily accessible area. Now we're going to bring this tube. Now, we're not going to tighten this one down a whole heck of a lot just to have a little play when we put that other elbow on. All right. Now I'm going to slip one of my hose clamps onto my intake tube here and my intake tube onto the throttle body right here. Make sure it's on all the way around, slip that into place. And then we'll put our tube into its place. Think I need to loosen up my hose clamp here just a little bit then I can slide that into place. Again, put that clamp somewhere that you can access it nice and easily. Tighten that down. And now we can get our pipe exactly where we want it, which is there, put our clamp around it.All right, now I have a 90-degree elbow here for part of our vacuum system. I'm going to thread this on my hand first, and then use a 16-millimeter wrench to just snug that up. You wanna get this into a position where it will accept that vacuum line, just get it right on there. We'll wait to connect all those until we get there. All right, now we're going to plug in our mass airflow sensor extension wire, and we are going to plug in just like that, lock it down, go underneath this elbow here and then connected to our stock mass airflow sensor. Clip it in, lock it in place. Now we can start reconnecting some of our tubes. We're going to be removing the sound tube in a minute, though. PCV goes on like that, you can hear it click in. And then this vacuum line again clicks in just like that. Now, we're going to get the sound tube out of the way and get our filter in place.All right. Now we're going to be using a push pin removal tool to lift up on this Christmas tree clip holding our sound tube down then we're going to use our 8-millimeter socket to undo this hose clamp. And then pull the sound tube out just like that. All right, now we're going to take our supplied plug, plug it into our sound tube. And we are going to over-tighten this hose clamp right here until it clamps down on that plug. Make sure it goes in evenly, [inaudible 00:15:38] use my [inaudible 00:15:39] a little bit there. All right, so that's pinched down on that sealing it all from the firewall. Push that pin back in. All right. Now we're going to slip our filter in place. I have that hose clamp on there, make sure it goes on evenly, top and bottom. Again, position that hose clamp in a spot you can easily access it.All right. Now, we're going to replace our engine cover. Very easy way to tell this is in place is just to get those little press fittings started. Make sure your oil fill neck goes through. A pain sometimes so I like to put it on an extension socket. All right, with those tight, we're going to be putting our strut tower brace back on. Putting this into place you can start over there because this side, you have to move this positive wire loom out of the way. Start your nuts. I'm going to tighten these pretty evenly across, don't want this side poking up more than other. All right. Now we're ready to reconnect our battery. This is a 10-millimeter, put our cover back on.All right. That's going to wrap up my install of the K&N Blackhawk cold air intake and for all things Mustang, keep it here at
