    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.

    Technical Note. The K&N Cold Air Intake is not designed for vehicles equipped with a Body Lift.

    • 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.

    Does the CAI void factory warranty

    • Cold air intakes usually won't void the factory warranty unless they require a tune. However, we recommend checking with a Jeep dealership to confirm.

      Should have bought earlier. Got 1.5 mpg.increase and I do notice better throttle response. Install was pretty easy after watching on YouTube. Tip, put together air box before pulling everything off. I did that one morning ( about 1 hr.) and next day took out factor unit and installed new. ( about 2 hrs.) seems to go easier for me that way.

      Love it!!!!

      Went in pretty smooth ...I'd say took about an hour to do...I was also installing a dual battery system at the same time ...so it seemed longer ...but it was pretty quick...looks great and works perfect!!!! The only complaint I'd have is it's a bit tight getting the sensors back in lol but...take your time and you wont break one like I did ....

      Immediate difference in power and sound

      I have owned my jeep for over four years and the only mad I had made on it was changing the antenna. Pathetic, I know. This CAI was brought about by my desire to have more horsepower, and it didn’t disappoint. I know my jeep very well, and I could tell there was an immediate difference in the responsiveness to pressing the gas pedal as well as the acceleration capabilities. Plus, that low engine growl is just so cool! Installation was fairly straightforward, but the instructions were horrible. No step told you which bolts/pieces to use; you had to keep referring back to a chart on the front page that had a minuscule diagram showing how things fit together, and hoping that you could follow the lines. Also, putting the filter cover on it was an incredible pain in the butt. The holes did not align and trying to bend and mangle the pieces together to get the screws to fit was incredibly challenging, even with two strong people doing it. I don’t know what the answer to this problem is, and if the intake would work as well without the cover (as some other models are designed) but it is a definite detractor. Other than that, I am very happy with this product.

      Good performance... misssing hardware

      Great CAI. I love the sound and I have noticed an increase of MPG. The only issue was that Hardware was missing and it made it hard to complete the installation. I had to go out to a hardware store and spend extra money on bolts that were missing.

      great performance boost for little cost

      this air intake not only looks and sounds great but the slight kick this provides makes you want to stomp on the pedal all the time and hear it roar. however at lower rpm the jeep is quite and civilized with a small noticeable change in horsepower. perfect intake to me.

      More Power!

      I was hoping for a little more mpg as my Jeep is my daily driver. It was never promised, I was just hoping. As far as performance goes, It is all that is promised. A definite gain in acceleration and somewhat noticeable horsepower. I don't drive my Jeep hard, so I don't feel qualified to rate horsepower. You can feel the torque on acceleration, and can definitely hear it! I like it a lot!

      Great overall

      Install took me about 2 hours all in all (kept going back and forth from the instructions and a YouTube video to figure out EXACTLY what bolts / screws / nuts went where, the instructions weren't so specific step by step). Only complaint is, like some other people, the crankcase vent hose is too small to fit over the nipple of the breather hose under the engine cover. I cut the hose on one side about an inch, pulled it over the nipple as far as I could, and used high temp auto electrical tape and a zip tie to secure it past the nipple. Now I need to figure out a more permanent solution. On a quick trip down the road though, definite increase in throttle response and more gutteral sound on acceleration. Will update with MPG in a few days.

      Took about an hour and a half to install, including removing the stock intake. Just be careful moving over the air intake sensor, those things are fragile and expensive.
