      Video Review & Installation

      Hi, guys. So, today, we're checking out the RedRock 4X4 Cold Air Intake in a Polished finish, fitting all 2018 and newer at JL Wranglers with the 3.6-Liter V6. So if you're in search of one of the most affordable options when it comes to a cold air intake, this option by RedRock is going to be right up your alley. Now, this is going to completely switch it up from the factory intake with an open heat shield design, a large conical and reusable filter, and a straight-through style polished intake tube. Now, this is going to be perfect for somebody who is looking for an increase in horsepower torque, and is also looking for an increase in efficiency as far as MPG is concerned, and even your throttle response.So, if you've noticed a lack in MPG, or you want a little bit of boost when it comes to your throttle response, this will be a great choice. Now, this will have a reusable oil filter that will cut out a lot of restriction from the factory option. So, it is going to increase your air flow increasing those gains, but this will last the lifetime of your Wrangler, so if you're looking for an intake that is going to give you some very easy maintenance, and that's going to hold up for a very long time, this, again, is going to be a great choice.So, I would like to mention, because this does have an open air box design or a heat shield design, that this is not really going to be for somebody who's doing a lot of water forging or a lot of mudding considering that this is a little bit more open and not as protected as an enclosed filter or enclosed air box design. I would recommend this to somebody who's doing some off-roading that does not require any water forging or is living in a drier climate and just wants a boost in the performance and also is looking for a sleeker look underneath the hood. Now, speaking of that, the polished intake tube and the black filter are going to do a really good job, creating a sleek look when you pop your hood, if you are looking to get rid of those factory plastics.Now, with that being said, I said before that this is going to be one of the most affordable choices, and this is going to come in at roughly $100. Now, in comparison to some other options, this is going to have a simple and no-fuss design. It's very straight and to the point, and I particularly like that out of this option. Now, some other choices are going to have a little bit more when it comes to the design, they may, again, have that enclosed air box design providing a little bit more protection. They may include a dial or an indicator saying that you need to clean your filter or you need to change your filter and so on. So, I personally like the fact that this is simple and to the point. It gets the job done, it's very functional, and it's going to give you those gains that you may be looking for out of a cold air intake, and it's also going to be incredibly easy to install.So, speaking of that, I'm going to give this a one out of three wrenches on the difficulty meter. You're gonna need some very basic hand tools to get the job done. There's really not much when it comes to installing this intake. Speaking of that install, let's jump into that now. The tools that I used for my install were an impact wrench, an adjustable wrench, pair of snips, a flat-head screwdriver, 1/4-inch drive ratchet, 14, 10, and 8-millimeter socket, and a trim removal tool. So, our first step to this install is disconnecting a couple of things from our intake. So, we can go ahead and take out the intake tube and the air box itself. Now, I'm going to start with our MAF sensor over on the side. There's a couple of clips holding the wiring harness to the intake tube, and also we want to get that sensor out of there so we can transfer it over to our new intake.So, I'm just going to start by unplugging it. And then there are two clips. I'm just using a trim removal tool to remove those. And you may have something else connected on the back by a clip. You can use the same trim removal tool in order to remove that over there. And then we can disconnect our breather hose over on the side. Now, this doesn't require a tool, all we have to do is just push down on this gray clip here and pull back. And then we'll be able to start disconnecting some stuff. So, I'm going to start with the two 10-millimeter bolts right up here at the front. Using a 10-millimeter socket, we can go ahead and remove those.After those are removed, we can loosen up the two clamps on the intake tube using an 8-millimeter socket. After those are removed or loosened up should I say, we can pop the intake tube off of the throttle body and off of the air box. Next, we can remove our intake box. Now, there is going to be a 10-millimeter bolt holding on at the front of the air box. I'm gonna use a 10-millimeter socket again. We can remove that. And then all we have to do at this point is really just give it a good tug up because it's held in by a couple of grommets down at the bottom. We can fully remove the air box. So, before we put our new intake together and get it in our Jeep, I did want to stop down and tell you guys a little bit more about this system, what benefits that this is going to give you in comparison to the factory one and some of the similarities and differences between the two sitting here on the table. Now, overall, as you can tell, this is going to be a big change from our factory system. And just a brief overview of what we have going on from the factory, we have an enclosed air box design, we have a paper element filter, and we also have a plastic intake tube that's going to have a couple of resonators on it. Now, overall, this works out for stock applications, however, when it comes to performance, you're not really getting a lot out of this intake from the factory.Now, moving over to this new option by RedRock, this is going to come up with a heat shield that's going to open up a lot of that space in comparison to the factory air box. That's going to allow better air flow and more air to come into that filter, and it is also going to seal to the hood to keep all of that hot engine bay air out. Now, in comparison to the RedRock option where the factory one kind of has a step up is a little bit of protection. It is enclosed, so it is going to protect the filter a little bit more, but when it comes to performance, that's where the RedRock one really shines. Now, this is also going to have a reusable filter. It is a large conical filter and it is oiled, so it will provide some better filtration than the factory paper element. It's also going to provide a better air flow and you can use it for the lifetime of your Jeep. All you have to do is pop it out, clean it, reoil it, and you can pop it right back in. Now, the factory paper element is only good for so many thousand miles. And as you can see, it can get pretty dirty and you will have to replace that for so many miles in comparison to this one where you can reuse for the lifetime of your JL. So, again, that is a big step up there. And since you can see that whenever you pop your hood, this is going to look a lot sleeker than at the factory setup.Now, moving on to the intake tube, like I said before, this is going to be kind of a standard set up for the stock design, but it is going to have a couple of resonators on it, which will cause a little bit of restriction considering that some of that air gets chambered in there and doesn't directly flow to the throttle body. Now, moving over to this new option by RedRock, this is going to be a straight-through style design. This is going to increase and streamline that air flow from the filter to the throttle body increasing your performance, and it is also going to have an aluminum design, which won't keep as much heat. And it's also just going to have a better look than the factory plastics, considering that this will have a polished finish, cleaning up the look of the inside of the engine bay. So, overall, this is going to really be a big step up when it comes to performance and when it comes to the underhood styling. And it is going to come with everything that you need in order to install it. It will be a pretty simple design, which I personally like. It makes it a no-fuss install and it really kind of is to the point when it comes to functionality and style. So, what do you say we go ahead and put this together so we can get it in our Jeep?So, the one thing that we do need to swap over from our factory system is our MAF sensor. This is just going to rotate out. There's going to be a little step here. It might be helpful to grab a flat-head, just kind of lift it over, and just twist it out and pull back. Now, we are going to have a grommet for our new intake. We're going to put that in the hole up at the front. Might be helpful, again, to grab a small flat-head screwdriver just to help it through. Then once it's sitting in there, what we can do is grab our MAF and wiggle that in making sure that it sits flush. So, once it's sitting flush, just make sure that it's rotated correctly. Next, we can take our seal, install this on the border, on the outside of our heat shield. You may have to trim it. I recommend doing this with a pair of snips. Now, there is metal inside of here, so just be careful. That's why I recommend a pair of snips. So, next, we can install our post. This is what is going to attach to the grommets where we need to install our air box here or our heat shield. You're going to be provided with a hex head bolt and a lock washer. And then we can thread this on to the bottom, same with the other mounting location. Then in order to tighten these down, I usually grab an adjustable. You could also use a 7/8-inch wrench, and then we're going to use a 14-millimeter socket to tighten those up.What we can do next is install our spacer. This is just going to keep the heat shield from rattling up against the battery box or the battery box bracket here. There usually is a 10-millimeter bolt that is attached. We do not have it in here. However, there is a welded nut on the other side. So, I'm going to take my spacer and I'm going to thread that in. It should be pretty easy to do by hand. And then once that's in there and pretty much hand-tight, we can grab our heat shield. And as you can see in between this air dam, there are two grommets. We can line those up and push those into place. Then you can put that spacer through and grab the flat washer and provided nylon lock nut, and we can tighten that up.I'm gonna use a 10-millimeter socket. Now, we can install our filter and our intake tube. What we can do next is install our mount for our filter. The larger side is going to go on the inside of our heat shield, and then we can grab one of our clamps and we can grab our coupler and put that into place. And we can also grab another clamp and put that into place. Now, for right now, I'm going to center this and snug this part up. We want to make sure that this is all the way over that mount for the filter. And that's gonna kind of hold it in place there. And we can grab an 8-millimeter socket, and I'm just going to snug this up for the time being. We'll completely tighten it down in a minute. All right. So, that is on there.Next, we can put the second coupler on the other side of the intake tube, making sure that both of those clamps are on because we're going to put that on the throttle body in just a second. Then we can line everything up, making sure that the intake tube is through and on the coupler on our heat shield. We can line this up and get this installed on our throttle body, set everything into place. So, now that both of our couplers are in place, both of our clamps or all of our clamps are in place, we can take that 8-millimeter socket and tighten those all up. All right. Then we can install our filter, making sure that our clamp is over our filter, and pop this down into place. You also want to make sure that the clamp is in a more accessible location, just in case you have to take it out and clean it. Once that is on there, we can plug in our MAF sensor and our breather hose. This is just going to slide on and click into place, and then we can plug our map sensor in. And after everything is plugged in and tightened down, then you're all set to go.So, that's going to wrap it up for my review and install.
