      Video Review & Installation

      Justin: The Series 63 from K&N will be for the 2018 and newer EcoBoost Mustang owners out there who might be looking to make the switch to an aftermarket cold air system and want to go with one of the most popular options on the site from an industry leader. Now, the Series 63 will not require the use of any custom or canned tuning and can be had for that low to mid $300 price point. Install according to the site, guys, gonna get a strong one out of three wrenches on the difficulty meter and will take about an hour or so to complete from start to finish, as we'll show you later in the video.So the Series 63 from K&N, otherwise known as their AirCharger system, is going to be one of the more budget-friendly options from K&N that will appeal to newer EcoBoost owners looking to add a little bit more performance and a little bit more sound but without ultimately breaking the bank. Now, in fact, at the low $300 price point, the Series 63 is going to be one of your more affordable options, again, from a big brand name like K&N currently here on the site.But let's talk a little bit more about your power expectations here with the K&N, and while the company doesn't offer any specific dyno numbers with this particular kit, I would say the realistic expectation, in my humble opinion, is going to be high single-digit, low double-digit gains. But ultimately, every setup is going to be different. Dynos are different. Conditions are different. So basically, in other words, guys, expect some gains, but I wouldn't expect anything like 20- to 30-wheel with an intake like this without any aftermarket tuning.Now, one thing you can expect here is a noticeable increase in volume under the hood of your EcoBoost, thanks to the open or exposed filter design. Now, a setup like this will result in a noticeable growl under hard acceleration coming from under the hood, along with some increased turbo sounds as well with the EcoBoost platform. What I mean by this is maybe a little bit more spool noises, as well as more of that recirculating or blow-off valve sound, which is a lot more audible with a filter design like this as opposed to a sealed enclosure like your factory airbox or other aftermarket systems that might incorporate a sealed enclosure. So long story short, guys, if you like hearing the extra sounds, if you like hearing that added growl, maybe a little bit more spool noise, or some of those more blow-off valve type noises, you're certainly gonna dig the open filter design like this. On the other hand, if you prefer more of a factory-like experience, you don't need all of those extra sounds, well, you might want to consider an aftermarket system that's going to incorporate a sealed enclosure instead.Let's move away from the benefits and talk a little bit more about construction and what's actually included with the kit. First and foremost, guys, I do wanna talk about your roto-molded plastic intake tube here. Personally, I'm a big fan of plastic tube designs such as this because they are really good at reducing heat and heat soak, and as you may or may not know, heat is oftentimes the enemy of performance. So a big-time fan of the roto-molded plastic tube.Now, on top of that, you are getting the K&N filter here, which is basically what the company has built its reputation on over the years. This guy is going to feature a few layers of a cotton gauze material. At that point, that cotton gauze is sandwiched between epoxy-coated aluminum screens and then lightly coated with their signature oil. Now, because the K&N does use an oiled filter, you can wash this. You can reuse it over the years and, obviously, recharge it with the K&N signature oil, being careful not to over-oil the filter itself. This is a design that's obviously gonna save you money over the years because, as opposed to buying a new filter every few thousand miles, basically throwing out the old one. Basically, clean it, re-oil it, and you're good to go.Now, we already talked about the tube here, the roto-molded plastic tube being great for resisting heat. Well, helping to resist heat even more will be the included heat shield that will isolate the filter from the hot engine bay air, along with the included weather stripping here, which will help that heat shield kinda seal to the underside of the hood. Now, it should be noted, guys, that, ultimately, if heat is your number one concern with an aftermarket system, typically, an enclosed airbox design is gonna be the way to go. However, if you're not the type of owner who sits in traffic all the time, or if you're not living in a crazy hot climate, or you just really value hearing the system and all the cool noises that you can expect with an open-element design, well, then, ultimately, this will be the best bet for you. So basically, it comes down to what's most important to you, guys, at home, what do you value most, and making your decision from there.After that, though, guys, basically, the rest of the kit is gonna be used to get everything in place. That includes your couplers here, everything is included, filter adapter, and, of course, all of your clamps and hardware. Now, the K&N, again, guys, has been made here in the U.S.A. It is backed by the company's 10-year or million-mile warranty just in case you run into any issues over time.Now, the Series 63, at this time, is not currently CARB certified, at least at the time of this video, but it does have a ton of positive reviews here on the site, over 100 4- and 5-star reviews, to be exact. So as always, guys, feel free to read up on some of those product reviews, check out some of the customer-submitted images, to see what this thing will look like underneath the hood of your ride before pulling the trigger. But now, let's shift gears and talk a little bit more about getting the K&N Series 63 installed on your EcoBoost at home. And to give you a better idea of just how the job will go down, check out our detailed walkthrough and tool breakdown right now.Man: Tools used for this install, needle-nose pliers, quarter-inch drive ratchet, quarter-inch drive extension, 7, 8, 10, and 13-millimeter sockets, 4-millimeter Allen head, and quarter-inch drive swivel.First thing we're going to do is disconnect our air temp sensor and take our seven-millimeter and loosen up our clamp here.Next, we're going to remove this spring clamp and remove this hose from our air intake tube. I'm going to take my needle-nose, squeeze this together.Once I get it off the tube, I can just move it out of the way for now. Now that we have this hose out of the way, we're going to remove our PCV by pushing the gray clip on the side and just lifting up. We'll get that out of the way. And now, we'll take off our clamp down at our turbo. Now, I'm going to take my quarter-inch drive with a seven-millimeter. We're going to loosen this hose clamp right here, coming off the turbo. I'm going to get in there. I have a swivel on here. You might want to do that. It makes it easier just to get in there and loosen that clamp up.Once we have that loose, now we're going to be able to remove our air intake tube. Now that we have all our clamps loose and our hoses removed, I'm going to pull this air intake tube off our turbo, down there, like that, and give it a tug up top. That's going to remove our stock air intake tube.Now that we got our air intake tube removed, we're going to remove our airbox. We're going to remove these clips right here, plus this 10-millimeter. We'll take the cover off first, remove the air filter, and then I'm going to lift this box right out. First thing we're going to do is take our clamps loose, pull the top of our box off, remove our stock air filter. I'm going to take my quarter-inch drive with my 10-millimeter. We're going to loosen this bolt up and take it out. Pull that out. Now, I'm going to just remove my airbox just like that, and now our old airbox and air intake tube is removed.So now that we got our stock airbox off, we're going to start by installing some of the parts onto our new air intake system. We're going to start first with putting our rubber on it. It's going to go all the way around this. Then we have some brackets to put on the air temp sensor. But first, I'm going to start by installing this. We're going to take it, and you're just gonna push it down on top and just bend it around.Now, once I got it all the way around, I'm going to make sure it's pushed down all the way. Now, we'll go on to installing our air temp sensor into our intake tube. Now, I'm going to install this rubber grommet into our air intake tube. I'm gonna get it started, push it down in. It's definitely a tight fit. So you're gonna have to move it around.Okay. Now that I have that in, now we'll install our air temp sensor. Now we're going to put our air temp sensor in. We're gonna have to push, like that, get it down in, and it'll go up to that little stop there. Now that we have that done, we're going to install our air filter holder in our airbox.So this air coupler here that holds our air filter, we're going to take these two Allen head screws. We're going to put them through the back here. That's going to hold our air filter once we get it in the vehicle. I'm going to start these. I'm gonna take my four-millimeter, my quarter-inch drive ratchet, snug these up.Now, we'll install some of our brackets onto our airbox. So now we have a bracket here that we have to install. We're going to take our 10-millimeter. We're going to mount our bracket. I'm going to put it through the other side, get it started here. And I'm not going to tighten it all the way yet because, once we get in the car, we might have to move this bracket around a little bit. But this 10-millimeter here, I'm gonna snug it up. And it's still able to move when we get it inside the car.So now, what we're going to do is install our rubber coupler onto our intake tube. The bigger end is going to go on to this. I already got it on. The smaller end is going to go to the turbo. I'm going to install this hose clamp now before it's in the vehicle, just make it easier. And we'll get it on. I'll take my quarter-inch drive. It's an eight-millimeter. I'm going to snug it up. Then I'm going to take my other hose clamp, make sure it's loose, and just hang it on there for now until we get it onto the vehicle.Next, I'm going to install the other rubber coupler onto our intake tube. I'm going to put our clamp on a while, slide this over, just get it where it's got to sit here. I'm going to snug this clamp up the 8-millimeter. I'm going to leave this one just a little bit loose. That way, if we have to pull it out for adjustment, we can still move it around. And then I'll just slide this one on. I like to put the hose clamps all in the same direction so, when you tighten them, they look nice. Next, we're going to go to the vehicle, install another bracket, and then we'll start assembling our air intake system.Now, we're going to install this bracket that was supplied in the kit with the 13-millimeter that was also supplied. It has a flat washer and a lock washer. There's already a hole that's threaded into the frame here. We're going to install this into that hole, and that's going to hold our airbox. So I'm going to start it and get it pretty tight, but still, it'll be able to move a little bit. I'm going to install it straight up just like that. Now, we'll get ready to install our airbox.Now that we have everything assembled, we're going to take our airbox. We're going to slide it down in place here and line it up with the screw down in the bottom of the bracket we stuck on. I'm going to take my 10-millimeter and get that started. Once I get that started, I'm going to take my air filter now. I'm going to put it in place and get it onto our air tube there so that it's where it's got to be and make it easier than when I bolt it up. I'm going to take my 10-millimeter, reach down inside here, snug up that 10-millimeter I started. And then I'm going to take my other 10-millimeter, and I'm going to line up our bracket that we stuck on on the side here. I'm going to stick that on. I'm gonna tighten that up.Last, take my eight-millimeter, tighten our clamp up on our air filter, and now we're ready to stick our air intake tube on. So now, we're going to stick our air intake tube in. I'm going to fish that down in, slide it onto our turbo, and then stick it onto our airbox over here. Just want to make sure it goes all the way around, like that. Push back on our tube over here, I might have to loosen that hose clamp up just a little bit. And there we go. And now that we have that on, we'll tighten our hose clamps, install our two tubes that we took off, and hook up our air temp sensor. Now, I'm going to tighten our two hose clamps here and snug this one back up. Now that I have those done, I'm going to take this wire connector they gave us in the kit. I'm gonna plug it in. It's just gonna make it easier to get it a little bit more length on that. Now that we have that done, we'll go down and snug our clamp up down at our turbo. Now, I'm gonna get in here to tighten up our eight-millimeter clamp here down at our turbo.Now that that's done, we're going to hook up our PCV and install our other hose. Now, we're going to install our PCV. I'm gonna fish it down through here, put it on top of our air intake tube. Now, we're going to install our hose on our tube. The spring clamp is a little tough to get it to go on once you get it down over. Now that we have that on, our air intake system is installed.That wraps up this review and install of our K&N Series 63 AirCharger cold air intake for '18 to '21 EcoBoost Mustangs. Thanks for watching. And for all things Mustang, keep it right here at
