    Review & Installation Video

    Review & Install Video

    Hey, guys. It's Sara with extremeterrain.com. 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 extremetrain.com.

        CA Smog Legal Aside from it "Passing" smog check does this kit come with the more important STICKER saying it is approved for use in CA?

        • Hello, unfortunately the RedRock 4x4 Cold Air Intake Kit - Black Wrinkle Coating (12-17 Wrangler JK) does not have a CARB #, therefor not being legal for use in CA.

        1 - I'd just installed my new air intake and I would like to know if i have to oil it ? 2- Need some washing tips for it to , first time that kind of air intake . Thanks Mitch

        • 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 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. https://www.extremeterrain.com/flowmaster-cold-airtake-filter-refresh-kit-8717-yj-tj-jk.html

        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.

            Review from RedRock 4x4 Cold Air Intake Kit - Black Wrinkle Coating (12-18 3.6L Jeep Wrangler JK)

            Certainly Cool

            With the excellent install video, the intake went in with very few hiccups. Be very careful removing the oxygen sensor. I looked at another video showing the removal of the clip. Just take your time and have a coffee. Only drawback for me (cuz I am old) is the added noise. Cool when I was younger but now near 60 I find it just slightly annoying. Having said that, the intake looks great, is cheaper than other brands and a no-brainer purchase.

            Easy install.

            The product was just as described and had all parts required to install. It really adds a great sound to the motor when you step on it. It seems to have added a bit more response as well. Installed at the same time as a RR throttle body spacer. The combination seems to have made a definite performance improvement.

            Great value!

            Install was pretty straight forward and easy. Just had to fight with the air sensor to remove it from the old one since it wouldn't come out easy. Once everything is removed from the old one, its was a breeze. Sound is good. We shall see on the MPG, not much on the performance side.

It took about an hour and a half all together, instructions were easy to follow. For the price you pay and the performance, it’s a great buy.

            Must have for Jeep folks

            This was easy to install, sounds great, does give a boost. I did it the same time doing a Magnaflow axle back kit and a throttle body extension. It’s literally like driving a whole new Jeep. Way more power even in higher gears going up hills. Box is tricky to install, pay good attention to the instructions. Instructions have been improved with pics and all, just take your time and pay attention. Install the rubber guards on the box before bolting it in place. A major bargain. I have about 1000 miles on it already, love it. Remove the negative cable on your battery first to avoid the engine light issues. I’m a novice and figured it out no problem. You can do this and you’ll love the sound and boost of not having your air restricted so badly.

            Exceeded Expectations

            First, I’ll just say......I’m not a mechanic. But I installed the intake myself. Outside of a few challenges with some tight spaces and having to blindly put a wrench on a couple of bolts, it was an easy install. Instructions that came with the unit are poor. Photos are dark and you can’t tell what’s what. So highly recommend watching a good installation video. Sounds great and looks great. You can feel a little boost in power. I was skeptical about any mpg impact, but based on first tank of gas, mpg went from 17.5 to 19.2. I’ll believe it after a few more tanks. I have a 2018 JK Sahara Unlimited. Highly recommend this intake.

            It was a fairly straight forward install. About 1.5 hrs. Added almost 1mpg and added a nice gravely sound when the throttle kicks up. I’m getting ready to pair it with the Red Rock exhaust so hopefully it will sound Bad Azz when it’s done. Lol.

            Jeep roar!

            Easy install, took about 30 minutes. Definitely a difference in throttle response and a big smile when you smash the peddle to the floor, very throaty tone as the 3.6 gobbles up the air. Mileage increase, not so much having to much fun making Jeep jeep roar.

            Easy install, nice sound

            Install was relatively easy, with instructions that were easy to understand. Just a few bolts and a sensor needed removal/replacement.
