      Review & Installation Video

      Hey, guys. It's Sara with And today, we have a review and install of the RedRock 4x4 Cold Air Intake in Wrinkle Black, fitting your '07 through '11 3.8-Liter Jeep Wrangler JK. This kit features an aluminum pipe with a powder coat black finish, a heat shield with the same finish and a conical reusable air filter. This intake provides better flow when compared to your factory airbox and it has no tune required. So one thing to note with this intake, because of the design, it will not protect against water as nicely as some closed box designs or some snorkels would. So if you frequently go off-road and encounter water, you might want to consider one of those options. But for the average Jeep owner just looking for a nice cold air intake, this one gets the job done. Coming in at around $150, this is the most affordable option in cold air intakes for your JKs. I'm giving this install a two out of three wrenches on the difficulty meter. It can be done in approximately two hours and features a directed bolt-up installation. All right, with that said, let's jump right into our install. For this install, we used a 3/8 drive ratchet, a quarter-inch drive ratchet, a 3-millimeter Allen key, 12, 10, 8 and 7-millimeter sockets, several extensions, a 10-millimeter wrench, cutters, and a flathead screwdriver. All right, so the first step in our install is to remove the plug for the IAT sensor at the back of your intake. You can push back on this red tab or you can use a flathead and gently push back with this. Once the red tab is released, press down and remove the connector. Using an 8-millimeter socket or flathead, remove the clamp holding your intake to your throttle body. Pull the PCV hose off the back of your airbox. Now we can remove the four metal clips holding the top of our airbox on, there should be two at the back and two at the front. With the top of our airbox free, we can now lift it out and remove it. Remove your air filter and set it aside. Now we can remove the lower portion of our airbox by gently lifting up and wiggling. This should free the three pins on the bottom. At this point, we're gonna remove and transfer over the IAT sensor from our old intake tube into our new one. Grab this and wiggle it free. If it's fighting you, you can lube this up a little bit just so that it will come out. Replace the sensor into our new tube into the rubber bushing here. Now we can assemble our airbox using the small hardware, washer and nut. Line up the plates on your airbox and get your hardware through. Make sure there's a washer on each of these bolts. Make sure you have a washer on these. Grab a 3-millimeter Allen key and a 7-millimeter socket and tighten these down. At this point, we can install the weatherstripping on the inside here where your air filter will go and also along the top. Line it up on the ridge here and just press it on. Press down on the weatherstripping and make sure it's seated as you go. If your piece is too long, you can trim it down. Now we'll take the larger piece of weatherstripping and run it along the top here and you do have to run it down this corner a little bit here. Get it started at the far corner. And when you hit this bend here, you might want to just give it a notch in the backside here with a set of cutters so that it can clear this bend a little easier. Bend the end of this weatherstripping down this corner and seat it along the side. All right, now that we have our factory intake on uninstalled from our Jeep, we can put it side by side with our RedRock intake and really check out some of the differences. Now right off the bat, you may have noticed the aluminum pipe which is powder-coated textured black which matches your heat shield. This is gonna be great for when your hood is closed, the heat shield is gonna protect your air filter against the heat from the engine and when your hood is open, it's gonna look great giving you that nice aftermarket appearance to your engine bay. This air filter is also washable and reusable which is gonna save you money down the road when compared to your factory paper filter. So this entire combination is gonna breathe better than your factory intake, giving you a little bit better throttle response and that nice aftermarket sound. All right, so let's get this installed on our Jeep. We do have to remove one 8-millimeter bolt that's holding on our fan shroud in order to install it to our heat shield here. Grab your 8-millimeter socket and let's get this off. Now we can install our heat shield, line it up with the 8-millimeter bolt that just came off. Grab your 8-millimeter socket and tighten this down. You may need a small extension to clear this. Grab your long hardware and get it through the holes in your airbox and also through the rubber grommets that we're attaching your factory intake. Now we can install the larger washer and nut on the end of the two long bolts. You will have to go underneath your heat shield to do this. Grab a 10-millimeter socket and wrench and tighten these down. Grab the two smaller clamps and slide them over the end of your pipe. Slide it over your throttle body, the smaller end of the coupler will be going to it. Get your clamps in place and then grab an 8-millimeter socket and tighten them down. We now install this spacer between the bottom bracket on our intake pipe and the heat shield. There should be a small hole at the heat shield underneath where your air filter will pass through and that's where we're gonna install this. You also want to grab two nuts, one for either side of the spacer. Grab the rubber spacer and line it up with the hole in your heat shield as well as the bracket on your intake pipe here. Make sure you put a nut on either side with a washer. Grab a 12-millimeter socket and tighten down the nut on the inside of your heat shield. Adjust your intake pipe so it slides over top of the stud. Grab your 12-millimeter socket and tighten this down. Grab your larger clamp and slide it over the top of your filter and slide your filter over the end of the pipe. Once your air filter is fully seated on your pipe, line up your clamp and tighten it down with an 8-millimeter socket. Grab one of your clamps and slide it over your PCV line and slide that line over the port on your intake. Grab your 8-millimeter socket and tighten it down. Grab your connector and reconnect it to your IAT sensor and press the red tab down. All right, so that is gonna do it for the review and install of our cold air intake. Remember for all things Jeep, keep it at

        4 2018 Wrangler - Wes2018 Installation Time: Less than 1 Hour

        Good Bargain Overall

        I waited until I drove this a few weeks to post a fair review based on direct observation. I hate trying to assess a product from the 5 star reviews and reading about 1st time buyers who are REALLY excited about shiny new parts in the box and super fast shipping. I choose a kit in the lower price range for a few reasons. Given the basic function and purpose of a cold air intake, manufacturing quality would have to be pretty shoddy to affect functionality (looks aside). The components in this kit are built well enough for the cost, and do look good so to spend twice the $$ on a higher end brand doesn't seem practical to me. I'm not a brand snob, so I trend toward functionality and "ok" good looks. The instructions are not newbie friendly by any stretch, but if you already know what you're doing, you should wrap this up in no more than an hour and a couple beers. So, opinions aside, my gains are as follows: 18.6mpg avg before / 19.2mpg avg after. Throttle response improvement in the lower gears is noticeable, but just slightly. On the highway in 6th, it takes a bit less throttle load going up the long slopes. Again, noticeable, but just a bit. If you sit in your jeep everyday on the same route you'll notice the minor performance improvements. You will also notice a throatier induction tone under load. I will add that over this test period I filled up at the same station with the same fuel grade every time. Also same routes and driver/driving habits daily so the mpg averages are over a broad enough span to qualify as baseline data. Overall, this kit is a good set up for the price. Also note that at roughly $50 for a replacement OEM quality air filter on this 3.6 you can invest $150 for a cold air solution with a reusable KandN style element that should last beyond several stock filter changes otherwise.

        Easy installation, and it does make the engine sound better at low rpm. gas mileage is also slightly better. Defiantly worth getting.

        So far good.

        Thank God for a kind brother-in-law who likes to install such things. He really had fun and said so. He rarely speaks, but this thing made him happy. He said it's was amazingly easy. Easy for him to say, and do. I'm very grateful to Scott and hope to reward him soon for having so much fun playing with my Jeep. Drove it 7 blocks to the local Dairy Queen and like the new bit of zip. Now in confinement 'till virus siege is over. Will probably go nuts 'till we can get out and leave pavement.

        Fitment was pretty good. I knocked off one star for lack of manufacturer support for not offering a filter sock. I did find one that just barely fits. It’s a... Spectre Performance 9731DK. You can find it on Amazon For about $13.

        Bought and installed the Red Rock 4x4 cold air intake. Have not had a chance to check performance improvement yet. Install was not as easy as they make it look and sound. Does not align as needed. Had to add my own “engineering” for the install!

        Cheap alternative to K N

        Install was easy enough, Like others have posted, the Throttle Body connector collar is a bit on the short side for the 3.8 wrangler but if you place it at its limits it all goes together well. Actually took about an hour, the selections below don't offer that selection.

      • The filter on the RedRock 4x4 Cold Air Intake Kit will come pre-oiled. At your normal filter replacement interval the filter should be removed, cleaned and re-oiled. Any filter recharge kit, such as the K&N Filter recharge kit would work.

      I have been doing research on which CAI to buy and I have read that it is common for the check engine light to come on. Will this CAI cause my check engine light to come on? 2015 WRANGLER

      • Check engine lights coming on after the installation of a cold air intake are usually attributed to installation errors or a retune being required but not completed. Unlike other cold air intakes on the market for the 3.6L V6 Wranglers, this RedRock 4x4 CAI does not require a computer re-tune and is engineered to work with the factory tune on the Wrangler.

      How easy is it to order a second RedRock air filter? and does Extreme Terrain carry them in stock?

      • While we do not offer replacement air filters for the RedRock 4x4 Cold Air Intakes, any universal replacement filter with a4" connection that is 9" long with a 5" diameter will work with the cold air intake.

      How do you clean the filter when it gets dirty? What products will I need to clean it? And how often do I need to clean it?

      • Thank you for your question! To clean an oiled filter you will need a refresh/recharge kit. I listed an option that we offer down below. Depending on your usage, a filter should be cleaned every 30-45K miles.
