    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.

        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.

        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.

        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

            Love it!

            Took me longer to take the factory system out. I couldn’t believe the quality of all the disparate pieces. Everything was metal (no plastic). Shocked for a system at this price. Can hear an audible difference when you step on the accelerator. I’ve got 35’s on my setup so I’m not ready to commit to noticeable power gains. That said, I enjoy the aggressive sound. This thing is solid and looks great in my super clean setup.

            Lots of pros-one big con

            Easy install, looks great, you do get an extra throaty sound coming from the engine bay when you accelerate hard, which I like. However, at cruising speeds, where the throttle is barely being pressed, there is a loud high pitched sound. I believe it sounds like air being sucked in. I can not duplicate while in park, but can duplicate with the throttle while moving endlessly. The sound is very noticeable with doors off and quite honestly sounds like brakes screeching. I put the old intake back on and it eliminated it. I tried to verify installation twice more and looked over everything. I couldn’t get it to stop. I will be returning.

            Easy as 1 2.....3

            I got this CAI in today and watched the video twice before install (be sure to do that, much easier). When I gathered all my tools and got started, I think it took roughly 45mins total if I count the 5 mins for removing the old air box. Now with all that being said, I’ll say this, you can hear this beast work! Hit the gas and you can hear this thing suck some serious air! Throttle response is noticeably better. Even just going easy on the gas, you can feel the quicker response. As for MPG, testing I did was cruising for about 20mins pre and post install at around 48mph. Wasn’t a lot of difference there, saw about 1 mpg after the CAI. Went from roughly 19.4 to 20.6 all in eco mode. Install is pretty straight forward and unless I missed it, there are 2 metal spacers that I didn’t see in the instructions or on the video. I put them on the bolts that went through the heat shield to secure it in the existing grommets, between the heat shield underneath into the grommets. Could be completely wrong but it worked and I believe may be more secure.

            RedRock cold air Rocks

            As a long time jeep owner, a cold air intake is the first mod i do! I like to let her breath. The RedRock cold air intake has proved to be a fantastic purchase. This CAI took no time to install and provided the throaty sound I was looking for. I saw a minor upgrade in fuel economy (1 or 2 mpb). The in the seat performance is quite noticeable in my opinion. For a budget friendly CAI you cannot go wrong with this bolt on mod.

            Red rock cold air intake

            I purchased this with a throttle body spacer. I noticed a difference in the sound from the engine. I can tell it draws more air in at mid range. Fuel mileage may have increased by .1 of a mile per gallon. This is after about 800 miles or so. I was hoping for more off the start power but it comes in much later than I expected. Overall I think it was worth the buy as opposed to bigger name brands that would do the same thing.

            it made an noticeable increase in power and mileage!!! it will pay for its self in a couple months of driving with the increase in MPG. it took me less than an hour to install and the best way is to what the video. I used lock washer on the screws that made up the box for more peace of mind. only question was is the filter washable and do I oil it???

            Strongly Recommended

            I will give you both the super quick review and the detailed review. In short, buy one of these as soon as you can. It makes a noticeable and significant performance difference for your Jeep. You'll love it. Now, here's a little more detail: I've run a CAI on other vehicles before with hit and miss - mostly miss - results. I put another brand of CAI on my '04 Dodge RAM 1500, 5.7L V8 hemi. The dealership promised 8-10hp increase and 2-3 mpg increase. Neither materialized. In fact, I couldn't find any difference whatsoever. I doubt that this is a brand specific issue which tells me that different engines react differently to a CAI. It also tells me that the V6 Pentastar engine, which is an excellent engine, is also air starved. Both my buddy and I have '15 Jeep Wranglers. Mine is Unlimted, automatic and has the towing package. My friend's is 2dr, standard transmission with aftermarket exhaust. The first install took about 2 hours. The second, less than 1 hour. The directions aren't very good but it's a simple install. The components are well made, tolerances are good and everything fits easily, the way it should. Stomping on the gas with the hood open, you could hear the filter chugging air. I have to say, I wasn't expecting what I found on the test drive. A few others have commented on the noticeable growl and I really like the way it sounds. This was an unexpected benefit. But the real benefit is acceleration gain from a standing stop. I won't put a hp number on it but it is significant. Very noticeable. It was even more noticeable in my friend's Jeep. I even stomped on the gas at 50 mph and heard the filter chugging air with that low growl and the Jeep surged forward. On top of all this, the RedRock is much less expensive than other CAI's out there. I can't speak for durability yet but as I said, the parts looked solid. I'll also be interested to see if I notice improved mph. All in all, a homerun. Buy one.

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

            Overall good

            Great product, I immediately was able to see an increase in throttle response and MPG with some good growl upon acceleration. My only gripe is that I have installed according to instructions and my check engine light will not turn off since it was installed. The code was for the sensor but I have tried reinstalling old sensor as well as buying a new one and the same issue persists.

            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.
