      Video Review & Installation

      Hey, guys. So today we're checking out the Redrock 4x4 Cold Air Intake fitting all 2018 and newer 3.6 liter V6 JL Wranglers. So if you're looking for some better performance for your JL at a very affordable price, this option by Redrock 4x4 is going to be a great choice to take a look into. Now, this will do a really good job at opening up a lot of airflow when it comes to helping your engine breathe better, increasing your horsepower, your torque, you're throttle response, which will be great if you're looking for a little bit of extra get up and go off the line in those higher RPM rangers, especially in situations like when you're getting on the highway or just driving around town. This is also going to help out with your efficiency, helping out your miles per gallon. So if you are a little bit concerned about that, this is definitely going to help you out a little bit there.Now, as far as the overall build, this is going to be a very streamlined and a pretty simple build. It's pretty straightforward. Now, this is going to have an oiled cotton filter, so it will be reusable, perfect for anybody out there who is a fan of an oiled filter and want something that they can maintenance overtime for the lifespan of the intake and overall the jeep itself. This is also going to have a heat shield design so it will be a little bit more open. This is still going to seal at the top, making sure no hot engine bay air is going to get to that filter, keeping it cold, keeping the filter running efficiently. However, the heat shield is not going to be as protected as an airbox design. So I would just keep that in mind when shopping around.So I would say this is more for somebody who is in a drier climate or a hotter climate, that's not doing a lot of water forging or a lot of mudding, they're not necessarily concerned about maximum protection, they're really just looking for something that's solid, straight forward and is still going to get a good amount of cold air to that filter. Not to mention the intake tube is going to be a straight shot from the filter to the throttle body which is going to get rid of all of that restriction. Overall, it is going to be a very efficient system. And like I said, this is a no-fuss system, very simple and straight to the point. And that's why it's going to be so affordable. So speaking of that affordability, this is going to come in at roughly $175, which in my opinion you really can't beat for a system like this. Now in comparison to some other choices, like I said, this is going to be pretty straightforward in the fact that this will have an open heat shield design.Some other more expensive options are usually going to have an enclosed box, whether that is made of aluminum, like this option or a plastic material. And then some other choices are just going to have a different setup as far as the filter is concerned. They might have a dry filter or they may have a filter that is a little bit smaller or a little bit bigger. It kind of depends on your personal preference. However, again, I think if you're looking for something that is incredibly affordable and is straightforward to the point, going to get the job done, going to get the performance that you're looking for out of your JL, then this is going to be a great option. Now as far as install is concerned, I'm going to give this an easy one out of the wrenches on the difficulty meter, nothing you can't get done in your driveway in about an hour with some pretty basic hand tools. So speaking of the install, let's jump into that now.The tools that I used for my install were a trim removal tool, an impact wrench, a flathead screwdriver, a pair of channel locks, a pair of snips, a quarter-inch drive ratchet, and an 8-millimeter, 10-millimeter, and 14-millimeter socket. So the first step of this install is obviously we're going to pop open our hood and then we can move on to our IAT sensor. We have to disconnect that sensor and get the clips removed from our intake tube. So for this, we're going to need a trim removal tool. So your IAT sensor or intake air temperature sensor is going to be right on the side here. We're just going to press down on that clip and pull back. Then we can remove the two clips that are holding in the wire to the resonator here. Using that trim removal tool, just going to pop those out of place. We'll put that to the side. Next, we can address this hose on the side here. All we have to do is press down on this gray clamp and pull back, get that out of the way. So next we can disconnect our intake tube. So we're going to loosen up the clamps and then take off the two bolts on the front here. So in order to loosen up those clamps, I'm going to use an 8-millimeter socket. There's going to be one at the airbox and one at the throttle body.Once the clamps are loosened, we can grab a 10-millimeter socket this time and we can take out the two bolts at the front. And then at this point, our airbox is still connected but our intake tube is not, so we can wiggle that out of the way, and then we can work on our airbox. So in order to get our air box out, this is only going to consist of one bolt, which is a 10 millimeter bolt over on the side of our quarter panel here. I'm going to take a 10-millimeter socket and remove that. And then once that's removed, what we can do is just give it a good pull up. It's going to be held in by a couple of grommets down at the bottom. You just have to give it a good pull and we'll be able to pop that out of place. So before we put our new intake together and get this thing installed on our JL, I did want to show you the factory one next to this new one side-by-side, give you a little comparison, show you some of the similarities and differences between the two.Now starting off is just a brief overview of our factory system. We're going to have an enclosed airbox design that's going to protect the filter inside. Now the filter inside is going to be a paper filter or a paper element that's going to do a pretty okay job at filtration, but not really a great job when it comes to airflow and performance. And then moving over to our intake tube as you can see, this is going to be a little smaller or pinched, and we're going to have a couple of resonators on there that are going to cause a bit of restriction when it comes to airflow. So overall it's an okay system. It's good for stock performance, but when you're looking for a little bit more performance and cold air, better airflow, better filtration, this is where this option comes into play. Now the heat shield design is going to be a big switch from our factory air box, which is enclosed. This is going to have a more open design, it's going to bring in a lot more air, but it is also going to come with a seal to make sure that it seals around the hood, keeping any hot engine bay air away from the filter. Now, speaking of the filter, this intake is going to come with a large conical filter. Now, this will be an oil filter, so this will be reusable in comparison to our factory one, which you will have to replace every so thousand miles when it does get dirty.Now, with this one, all you have to do is clean it. You can re-oil it and then you can pop it right back into your intake. Overall a nice system and it's also going to have that oily residue that's going to trap all of the micro contaminants, dirt, dust, whatever's going to come in contact with that filter. This is going to do a really good job at filtering that as it says in the name. But it's also going to open up a lot of space for airflow at the same time. So you're getting some better performance when it comes to optimizing the airflow and also optimizing the filtration so you kind of get the best of both worlds when it comes to this filter, not to mention it's a very large filter. It's going to do a good job at tucking in a lot of air to get to your intake manifold.Now moving on to the intake tube, as you can see, this is not going to have any resonators and it is going to be a straight-through flow style design in comparison to our factory one. So this is going to optimize that airflow and optimize that performance, getting the air as a straight shot from the filter directly to the throttle body. Now, the heat shield, as well as the intake tube are going to be made of an aluminum material. So I would keep that in mind when you are shopping around. But those are going to have a nice textured black powder coat finish on top to protect that aluminum underneath from, of course, any corrosion, but it's also gonna add a nice off-road or aggressive touch to the inside of your engine bay. Not to mention, this is going to come with everything that you need in order to install it, silicone couplers, as well as all the clamps and hardware in order to get it in your JL.So speaking of that, why don't we put this together and get it installed on our jeep? So our first step on the table to getting our new intake set up is to swap over our IAT sensor. So this is going to be located right on the side over by the resonator. Now we just need a little flathead screwdriver. You could use really anything for this, a pick would work as well. But you just want to make sure that tab goes over the little slope here and we can twist it, give it a good wiggle and pull that back. It's going to have a little O-ring around it so it might take a little bit to get it out of the factory intake tube, but once that's out you can just put it down. So we can grab our new intake tube and our provided grommet, and we can get this fitted into the intake tube.It might be helpful to grab that flathead that we used just to get it lined up at first. All right. Once it's sitting flush, just want to make sure that it's sitting flush on both sides, we can take our IAT sensor and wiggle that down on it. Now it might be helpful to actually grab some white lithium grease or a little bit of grease just to put on that O-ring there. Once that's flush, you want to make sure that it's turned to the correct angle. Just want to make sure that it's facing the opening so it gets the right read and then we can work on prepping our heat shield. So what we can do at this point is take our weather stripping, and we can start to install this around our heat shield. Now, if you do need to trim it, you can. Just make sure that it's sitting over those corners correctly. So if you do need to trim it, I just recommend that you do so with a pair of side cutters, this is going to cut through it the easiest. There is metal on the inside of this stripping. So side cutters are usually the best when it comes to that. So once that is on, we can install our studs down at the bottom.Now, these are going to go into the grommets that are at the bottom of where the airbox or the heat shield is secured. So what we're going to do is just take our provided bolt and lock washer and thread this on here. Then we can grab a 14-millimeter socket and tighten those up. Next step we can secure the double-sided isolator to the side of our heat shield here. Now, this is going to act as a secure point for the side of where our airbox is usually secured. So this is going to go through the mounting point over on the side here. I'm going to take the flat washer and nylon lock nut and loosely thread that on. And once we get into the engine bay, we'll tighten that up. But at this point, we're ready to head over to the jeep. So first, I'm going to start by dropping in the heat shield. As you can see, there are two grommets on the bottom there. Now, if they came off with the actual airbox when you took out the factory air box, you just have to pop them off. And they go on either side of this little air dam here. So what we're going to do is just line up those posts, give it a good push down on in.As you can see this little isolator over on the side, we're going to have a welded nut here. Now there should be two bolts here. One of our bolts is missing, but this is actually going to thread into that. So we're going to lean this forward and we're going to try to thread this into place. So what we can do is take a 10-millimeter socket and we can tighten up this nut here. And then once it's tight, it should actually... So if the isolator is having a little bit of trouble moving, you could either install it first before the airbox. I like to install this airbox first, just so we know where everything's going to be before we pop this into place. But you can take a small pair of channel locks and just turn it to tighten it up against this bracket here if it's not tightening by hand.So once that's tightening onto the factory bracket, what we can do is take a 10-millimeter socket and tighten up this nut here. So now we can install our intake tube. We're going to have two different style couplers here. The straight coupler is going to go right onto our throttle body and the other one is going to go from the intake tube to the heat shield over there. So we're going to focus on the throttle buddy one for the time being. And you want to make sure that the hardware for the clamps is facing in a good direction for you to be able to tighten it and adjust it later. So I'm just going to pop this over our throttle body to start.Now, if you do have to loosen up the clamp a little bit, just to get it over the throttle body, we can do that then we can pop in the intake tube. Now once the intake tube is on the throttle body, we can install our second coupler down at the back, making sure that it is on all the way and that our clamp is again facing a good position. Then we can take the piece that's going to attach to the intake tube to the filter. Now, the filter is going to go around this larger piece and it's going to go through the heat shiled just like that. So we're going to attach that, make sure it is going around both the intake tube and the mount. So once all of those are mounted up and all the clamps are lined up, we can tighten everything up with an 8-millimeter socket.Next, we can grab our filter and we can pop it over the mount there, making sure that it's sitting on there correctly. We can make sure that large clamp is over that filter and then we can tighten it up using that 8-millimeter socket. So last but not least, we can make sure that our hose is attached, give it a good push down and then we can plug in our IAT over on the side. Once that clicks and you make sure that everything is secure, then you're all set to go. So that is going to wrap it up for my review and install.
