      Merideth: If you're in search of some better performance for your 3.6 liter, this K&N Series 77 High Flow Performance Cold Air Intake will be a great addition to your 2020 or newer 3.6-liter Gladiator. Now, this intake will do a great job of getting rid of that restriction that your factory air box had to offer, replacing it with a high-flow setup that will help your engine breathe a lot better. Not to mention, this will be a great addition if you're tired of swapping your factory filter every couple thousand miles and you're looking for a high-quality intake system that will offer better filtration and better longevity to not only the filter but also your motor.Now, by increasing the airflow, you will be getting some better horsepower, torque, and even some better fuel efficiency. And this intake will do exactly that without needing a tube.When it comes to the horsepower increase, K&N lists a 10-horsepower increase at 5600 RPM. So, keep in mind, those horsepower increases will be at the higher RPM ranges but you'll definitely feel that in your throttle response, especially when hitting the gas, like getting on the highway.This will also have a heat-shield application to prevent any hot engine bay air getting to the filter but, if you do go off-roading in a wetter climate where you come in contact with mud or water often, I would just keep in mind that this is not as protective as the factory air box or a closed system will be. Now, in addition to the performance, you'll also be getting a sporty appearance underneath the hood with the polished intake tube and the red filter.This kit will come with a high-quality oil filter that will trap all of the contaminants before getting to the intake system and will be reusable for up to 100,000 miles for your Gladiator. And the heat shield and intake tube will be made of durable aluminum materials and the intake tube will be polished for a more classic appearance and the heat shield will have a textured black-powder coat finish on top. Now, this kit will come up with everything that you need in order to get this installed in your JT, including all the clamps and the seals and the hardware and does not require a tune in order to be installed, making this very straightforward.When it comes to the price, this will come in at roughly $500, putting this at a pretty average price point for a high-quality intake system. Now, other options on the page may come in different configurations with different style components that will change up the performance slightly. Now, for example, some may come with a dry filter instead of an oiled filter. Not to mention there are some of those options that will come with a air-box design or a closed-box design, compared to this heat shield here, which will provide a little bit of extra protection but won't be as high-flow as this choice.Now, in my opinion, I think, if you're looking for a premium choice for a high-flow cold air intake that's gonna give you a good amount of performance and a sleek look underneath the hood, then this is gonna be a great choice.Now, like I mentioned before, install will be very straightforward at a one out of three wrenches on the difficulty meter, taking you about an hour to get the job done with some pretty basic hand tools. Now, at this point, we can head over to the shop and check out a detailed breakdown of the install. So, it's gonna wrap it up for me, let's go ahead and get into it.Man: Tools required for this install include a ratchet, a 7/8 wrench, a clip remover tool, a 4-mil Allen bit, an 8, 10, and 13-millimeter sockets. What's up, guys. Today we're gonna be installing a cold air intake on our Gladiator. So, let's get started.So, to remove our stock intake, we have a 10-millimeter bolt on the passenger-side fender, two 10-millimeter bolts on the front of the engine bay. We have to disconnect our PCV line, which we can do by pressing the tab and pulling out. We'll disconnect our air-temperature sensor, our clamp on our throttle body, and these two push clips on our intake tube.So, first, we'll remove our three 10-millimeter bolts. So, I'll grab a 10-millimeter socket and we can get this first one out. Next we can get the two on our rad cover. Now we can pop out our two push clips and remove our air-temperature sensor. And now we have a little black tab on the right side here that we can press in and pull out, and then we can twist our sensor out of place.Next we can disconnect our PCV line by pressing in on this gray tab on the right side, pulling back. And then we can loosen the clamp at our throttle body using an 8-millimeter socket. And now, with everything disconnected, we can pull back on our intake tube and lift our whole intake out of the truck.And then, once we have our whole intake assembly lifted out of the truck, the only thing we have left to do is remove this 10-millimeter bolt right here. Our aftermarket air box is gonna be bolting in here. We'll take a 10-millimeter socket and get this out.So, now that we have our factory air intake taken out of the truck we can start to assemble our air box. Now we have these two posts that are gonna go into our grommets to secure it down. These are gonna go on these two holes. To mount them up, we're gonna be using our M8 bolt with a locking washer and a flat washer. And that's gonna come from the inside. And then we can thread...and we'll just do the same thing for the other one. And then, to tighten these down, we'll use a 13-millimeter socket. And then, to grab onto these legs, we can use a 7/8 wrench.Next we can install our filter coupler. This is gonna come in from the bottom side. And then from the top we're gonna use our M6 Bolt with a locking washer and a flat washer. And we can just thread that in from the top. And then we can take a 4-millimeter Allen bit to tighten these down.Next we can attach our filter to our coupler. And I'll slide our clamp over the edge of our filter. And then we can slide it on just like that, rotate our clamp up into position, and take our 8-millimeter socket to tighten it down. Now we can run our rubber seal around the outside of our air box.Next we can install our intake tube into our air box. So, we have our coupler. It's nice and labeled with a number on there that the directions correspond to, to keep them straight. So, we can slide our clamp over that, slide that on there. And then we'll take our other clamp on the other side, slide our intake tube into our coupler. And then, once we have both clamps where we like them, we can tighten them down with an 8-millimeter socket. And then our last step, before we get this into the truck, is to take our air-temperature sensor and push it into the grommet on our intake tube.Now, the last thing we have to do before we drop our intake into our engine bay is to install our coupler onto our throttle body. So, we'll grab a clamp and our coupler. And then, once we have that in place, we can take our 8-millimeter socket to tighten down our clamp.So, now we're ready to get our intake into our engine bay. So, we can slide our other clamp over the coupler on our throttle body. And then we can lift our intake into place. We're gonna line up these feet here with our grommets that our stock air box came out of. I'll push it down into our grommets to lock it into place. And then you can get your intake tube and press it into the throttle body coupler.Now we can take our other M6 bolt. This is the one with the hex head. We're gonna be putting this through the hole in our air box where we took that bolt out before. And we have a spacer for in between, so, we'll thread our bolt through, get it through our spacer and then down into that hole. And then we'll take our 10-millimeter socket to tighten that up. And now all we have left to do is reconnect our PCV line, tighten down the clamp on our throttle body, and reconnect our harness for our air-temperature sensor.So, that'll wrap up this review and install of the K&N Series 77 High Flow Performance Cold Air Intake for your 2020 and newer 3.6-liter Jeep Gladiator JT. Thank you for watching. And for all things Gladiator keep it right here at
