    Review & Install Video

    I'm Ryan with ExtremeTerrain.com and this is my review of the K&N Cold-Air Intake, available for all 2007-2016 JKs. When taking a look at these cold-air intakes, you have a couple of different ones to choose from. One is the 57-series which is a carb-exempt, 50-state legal intake, the 63 which is not legal in California but should give you a few more horsepower, and the 77 which is the aluminum version of the intake. A cold-air intake on a Jeep is for somebody who wants a little bit more sound out of their engine, who wants a little bit better throttle response, and possibly some increased miles per gallon. A cold-air intake is not going to provide a ton of horsepower gains on a Jeep just because the factory intake isn't that much of a bottleneck. However, a lot of people do feel a little bit of a power increase after installing something like this. It is important to note that when you install a cold-air intake on your Jeep, you do get rid of the factory air box, which can be a little bit detrimental if you're somebody who takes your Jeep off-road in wet conditions a lot. But, if you do decide to go with a cold-air intake on your Jeep, the K&N ones are a good way to go because they're moderately priced, and they all include K&N's famous reusable and washable filter. Depending on which series you choose, you're either gonna get a polyethylene or an aluminum air intake tube that's molded specifically to fit in your Jeep and designed to work with your factory vent and air sensor. You'll get a heat shield and all the brackets and hardware necessary to get everything installed, including a washable and reusable K&N air filter. Now, because this setup is designed specifically to bolt into your Jeep, it will be bolt-in. You won't have to cut or drill anything which makes the installation really easy. However, because of that, it's very important to make sure you get the one that's designed for your specific year because Jeep did change engines. Because this is designed to be completely bolt-in, the install becomes very easy. The first step in the process is to remove your factory intake tube and air box, then install the heat shield and all the brackets that come with this kit. From there, you'll install your air filter and, finally, your air tube. The whole installation should take about an hour and you won't need any specialty tools, just some hand tools. Now, there are a bunch of companies out there making cold-air intake setups very similar to this, and some of them are less expensive than this one. This does come with the washable and reusable filter which may be worth a couple more dollars to you. It really just comes down to your budget. If you want to get one of these setups that's similar, that costs a few dollars less, I think that it'll have the same effect on your Jeep as this one will. So if you're looking for some extra throttle response, a little more sound from under the hood of your Jeep or a few extra MPGs, a cold-air intake might be the way to go, especially if you're somebody who takes your Jeep off-road only where it's dry or stays out of the puddles. If you're looking for a cold-air intake and you want one that has a reusable filter, the K&N is a really nice option. So that's my review of the K&N Cold-Air Intake, available for all 2007-2016 JKs that you can find right here, at ExtremeTerrain.com.

    Superior Performance.The K&N Series 77 High Performance Cold Air Intake is specifically designed to provide improved throttle response and guaranteed horse power gains. Completed with a washable reusable performance filter you'll also cut out the costly expense of replacements. This intake features an air dam and a stylish polished aluminum tube to assist in providing colder, denser air to your engine faster for effective power gains, whether you're on or off road. 

    No Tune Required. Unlike other cold air systems on the market, the K&N Series 77 filter requires no custom tuning or re-programming of your Wrangler's computer to operate. Simply bolt it on and you're ready to go, enjoying better fuel economy and performance with the turn of a few wrenches.

    Increased Airflow. The K&N Series 77 upgraded filter allows a higher amount of air to enter your Wrangler's intake, letting your engine breathe more combustion-aiding oxygen for better performance and throttle response. The stock, asthmatic intake severely restricts your Wrangler's ability to pull in air, but the Series 77 provides the perfect solution. The Series 77's polished finish adds some nice underhood styling, too.

    Durable Construction. Designed to replace your JK's weak factory intake, this kit features an aluminum tube to provide superior air flow without weighing you down. All the necessary hardware for installation is included in the kit, along with stainless steel clamps and accommodations for your mass air sensor. This intake is finished with a large, 6 inch red cotton gauze filter, to provide increased filtration over your flat, factory air box, and is easily washed and reused for continual performance.

    Installation and Warranty. This kit is easily installed with common hand tools for a straight forward installation that generally takes 90 minutes or less. Backed by K&N's Million Mile Warranty, this cold air intake provides both you and your JK with unrivaled security and performance for years and the many miles to come.

    Application.The K&N Series 77 High Performance Cold Air Intake is specifically designed to fit 2012-2018 Jeep Wrangler JK models with a 3.6L engine.

    CARB Certified. Best of all this K&N Series 77 High Flow Performance Air Intake Kit is 50-state smog legal for the 2012-2014 Model Years under Carb EO# D-269-48.

    WHAT'S THE REAL DIFFERENCE BETWEEN THE RED ROCK COLD AIR INTAKE @ $153 VERSUS THE K N COLD AIRE INTAKE FOR $344?

    JIMQ

    • K&N will offer a bit more gains, as well as arguably the best filter on the market against Red Rock which will have a nice filter, but not quite the quality of a K&N filter.

    Hello, I want to get a cold air intake that will work with the edlebrock supercharger. Do you know if the K/N one will and if not which ones will work in concert with the supercharger? Thanks!

    • The Edelbrock Supercharger Kits come with a specific CAI for the system. We cannot guarantee that the K&N Series 77 High Flow Performance Cold Air Intake will fit and function properly with the Supercharger.

    will this product give a stock 2015 JK a good sound to it? I want more of a growling sound but I don't wanna change the exhaust system just yet, what do you recommend?

    awarner196

    • The K&N Series 77 High Flow Performance Cold Air Intake will increase the engine sound level, which typically will be a bit deeper and throatier than what an exhaust will do, though at a much lower volume than an exhaust.

    I just installed this cold air intake and was wondering if I have to be careful going through puddles at all? I know of friends that have gotten water in their engine in low cars...

    Anonymous

    • Hello, As long as you are not blasting through puddles you should be okay. On smaller cars the air intake has air channeled in from the wheel well. This is not the case on jeeps.

      Thicher gage steel

      Works as expected, although the intake tube is about the thinnest steel they coul possibly use. I actually began to crush one end by HAND tightening the stainless bands on the end.

      Get what you would expect from an aftermarket intake. Responsive pedal and a deeper growl. Would recommend if you're looking for a little more excitement out of your breadbox.

      Cold air intake

      I purchased the KandN cold air intake and installed it in about an hour and a half. The instructions were easy to follow and the old air intake came out easily. The new parts fit well and the only problem I found was the oil breather hose would not fit on the engine connection. It was too tight. I’m going to try putting it in hot water and then see if I can get it to slip on. Otherwise, everything seems fine. The throttle response is much better. I will check to see if mileage is better. Power seems better but not able to measure.

      Breath Easy

      Cold Air Intake has made an improvement in engine response. It took longer than expected to install due to a fit problem of the filter cover and wrong size crankcase oil vent hose. Hose is a 1/2" , but it is a fuel hose which is to stiff to stretch over the existing plastic nipple on the engine. Excellent product and guaranteed to increase horsepower.

      Performance gains

      Definitely recommend this kit. Took about a little over an hour to install and performance gains were immediate! I have noticed an increase in gas mileage between 2-3 mpg and averaging around 21 mpg (well if I don't want to hear the throaty growl of the intake). It was been installed for over 3 weeks and no fitting complaints. Everything is solid!

      Great sound and performance, difficult install

      I am an admitted novice, but I found the parts for the lid of the intake to be VERY difficult to fit. In fact, the front lip of the lid is not attached as I type. Make sure to have a socket set prior to starting this project. You will need it to take off one of the bolts and to reattach it after install of the intake. Removing the intake and placing the new intake was the easy part! All of the auxiliary stuff proved most difficult for me. That being said, the sound and performance gain are great! My wife drove my Jeep yesterday and called and asked why the engine sounded so different, then she said, "Oh yea, you installed that air thingy!" HAHA, yes I did...

      Followed the directions and was super easy to install. Took me 30 minutes and I have no skills in mechanics. Just need the basic tools they tell you on the installation package and there you have it. Gives my 2014 JK a more throttle-like sound, definitely some increase in MPG and response in my Wrangler. Definitely recommend!!
