    Review & Install Video

    Hey guys, I'm Ryan with extremeterrain.com and today I'm here to review the RedRock 4x4 cold air intakes. Now, RedRock offers two version of this. One is for the '07 to '11 Jeeps with the 3.8 liter motor and the other is for the '12 to '16 with the 3.6 liter. So make sure you get the right one for your rig. Now these cold air intakes are going to give you a few additional miles per gallon. They're going to give you a little better throttle response and you're definitely going to notice some more noise from underneath the hood when you step on the throttle. Now unfortunately, you're no longer going to have that factory air box, which is there to keep some water out of the motor when you're off-roading. So, if you do plan on going off-road and doing any water crossings, you're going to want a snorkel if you want a cold air intake. These systems are really simple. There isn't much to them. This one works well. It looks good and the black wrinkled finish matches some of the other under hood components. This is definitely one of the least expensive systems on the website. But to be honest, I don't see a reason to spend more on a system with a similar design. This one works great, it's no frills and it'll keep some money in your pocket for your next mod. Now this cold air intake system completely removes the restrictive factory air box in place of a air intake tube, a heat shield and a conical air filter, which is both washable and reusable. Now this system includes everything you need to get the cold air intake bolted into your Jeep. You should only need a couple of tools, a few wrenches, some Allen keys and a flat head screwdriver and less than an hour of your time. If you're curious what other people are saying about this intake system or you want to see pictures of it installed on other Jeeps, make sure you check out the customer submitted images and reviews on the website. So that's my review of the RedRock 4x4 cold air intake. It's an affordable no frills system that gets the job done. Now remember there are two versions of this system, one that fits the '07 to '11 JK and the other the '12 to '16. So make sure you get the right system for you. No matter what you need, we have it right here at extremeterrain.com.

    Improves Power. A RedRock 4x4 Cold Air Intake kit will completely replace your JK Wranglers restrictive factory air box and paper filter element with a high flow filter assembly for a noticeable increase in horsepower and torque, all while providing filtration of harmful power robbing dust particles.

    No Tune Required. Unlike other Cold Air Intakes on the market for the 3.8L V6 Wranglers this RedRock 4x4 CAI does not require a computer re-tune. The engineers at RedRock 4x4 really did their homework to improve your JK's power using the factory tune.

    Reusable Conical Filter. Included in this RedRock 4x4 kit is a High Flow reusable conical air filter. So there is no need to go out and buy a new filter every few thousand miles. Just clean the filter, re-oil it, save money, and go!

    Easy Installation. The RedRock 4x4 Cold Air Intake kit is engineered to be easily install with just basic hand tools. There are no modifications required for a clean straight forward installation. All parts and instructions are included.

    Not CARB Certified. This RedRock 4x4 Cold Air Intake is not CARB certified, therefore it is not legal for use in California or other states adopting California emission standards. Not legal for use on pollution controlled motor vehicles; intended for off road use only.

    Application. This RedRock 4x4 Cold Air Intake System is specifically designed to fit the 2007-2011 JK Wranglers equipped with the 3.8L V6 engine and does not require re-tuning the vehicle's computer for operation.

    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?

    • 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.

    Does this intake actually come with a K N filter or is it another brand ? I’m looking for specifically a K N .

    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

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

      Sounds good!

      Even my wife likes the aggressive sound it makes under heavy throttle. I will agree with other reviews that the instructions are not that great. Specifically the fact that there is not any guidance on the best way to remove and re-install the intake air temp sensor. I checked that installation took me an afternoon by the time I went and bought another IAT sensor after carelessly breaking it as I mounted the tube to the throttle body. I could do it in less than hour now that I know the trick to removing the IAT and then after putting it back in the new tube, rotating it in to position.

      Noticeable Air Flow

      For the money, this is a great product. As good or better than the others at twice the cost. Does produce a nice sound under the hood. Some might find it too loud, but I like it. Lets me know the air flow to the intake is great.

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

      Air intake

      I bought this hoping for a bit of better throttle response from 2nd to 3rd gear! Very happy so far, great sound to it and much better response.. I'm giving a 4 because putting the filter onto the tube,is very tight and took myself and son to get it fully seated properly Otherwise I'd give it a 5.

      Awesome Modification

      Overall this product is very nice. It fits very nicely, sounds awesome, and increased the horsepower just a bit. As you get on the throttle, you will feel the front end of the jeep rise a little more than usual, and it picks up speed a little faster than with the stock intake. Love this intake!

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

      Terrible instructions, product seems okay so far

      Don't even bother reading the included instructions - just find an install video online. The instructions leave out several tools that are **required** for the installation - wrenches in several sizes and snips/cutting tool - and doesn't tell you what to do with half of the hardware. Even following an installation video I was left with a half full bag of hardware at the end that I still have no idea what it was for. I honestly expected the instructions to be at least decent considering the reviews. They weren't. Watch an install video that actually explains what goes where. The product does change the sound of the engine a little bit but I did not notice any change in the performance of the engine. I have not run it long enough to determine if there is any improvement in fuel economy.

      Nicely priced intake!

      I had bought this not knowing what I was going to gain performance wise, and I can say that I am not only freeing up a little bit of horsepower but I am also gaining more fuel efficiency, I noticed around 3-5mpg more which isn't all that much but its a jeep not a Prius they aren't supposed to be fuel efficient, so gaining any more fuel efficiency is a god send, I would definitely recommend this cold air intake by redrock 4x4 to anyone who does a little more driving with their jeep or someone who's jeep is their daily driver. the instructions are very straight forward and installation took me no longer than 45 minutes.

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

      Install was really easy.

      I purchased the CAI for my '18 JKU because I wanted the added power and throaty sound. The Red Rock definitely delivers in that department. I was also really hoping to get another mpg or 2 out of it... Not happening. At least not for my Jeep. Actually, it dropped. I was averaging around 17mpg before. Now, I'm lucky to see 16. That's the only reason I only have it 4 stars. But, the install was super easy and it definitely has more passing power.

      Nice little performance boost

      I've been using this cold air intake for just over 6 months now. I purchased this hoping to let the engine "breath" a bit better. Installation was straight forward, remove the old air filter box and duct work, install the bracket, tube and filter and you're done. In my case the threaded rod that secures the tube to the bracket was short by about a 1/2 inch. A quick trip to the hardware took care of the issue (reason for afternoon install time rating, it should have been a hour project) . After installation the engine seems to have a bit more pep and I'm seeing a couple of miles per gallon of gas mileage gain (city driving), and when you hit the peddle hard, you get that woosh sound of air sucking into the intake ;). It's been holding up well with my weekend Florida off road tips and and I haven't notice any issues with water getting on or around the filter when I hit the occasional mud hole

      The filter whistles

      I like the look of the intake and I think it helps with throttle response but it has a high pitch whistle every time you step on the gas. It’s annoying. Thinking about installing a different filter.

      Installed with a rugged ridge throttle body spacer and am happy with the result. Didn’t take long at all to do and now my throttle lag is gone. Not too sure how much my gas mileage has increased since I’m having a hard time driving conservatively with the extra acceleration.
