      Review & Installation Video

      So if you own a '13 to '18 3.6-liter powered Ram 1500, you're looking for an excellent first mod, you want to clean up the engine bay with a really cool intake, something that's old school looking but more importantly you want to make some impressive horsepower and torque gains without actually tuning your truck, then you should be checking out the K&N Series 77 cold air intake. Underneath the hood, let's face it, that factory intake system is pretty ugly. You got that really bulky plastic box there with that paper filter kind of suffocating that motor and you got that really ugly plastic intake tube with that cover over there. It just doesn't look that good in my humble opinion. K&N does away with all of that, they got a classic kind of hot rod look here. You got the open element design. You got a powder-coated heat shield here which does retain the factory cold air inlet by the way, getting that nice cold dense air to the motor to make that performance and you got this really nice metal intake tube here which is aluminum, by the way, it's not steel, so you're not going to have to worry about that rusting out on you. This also installs very easily. Our site says it should take you two or three hours with moderate skill. But honestly, this is probably one of the easiest installs you can tackle. I'm gonna give this a very soft two out of three wrenches on my difficulty meter. You only need basic hand tools, you should be able to get this done in about an hour or two and that's honestly if you're taking your time. So again, you want a good first mod for a 3.6-liter powered Ram 1500, you want to clean up underneath the engine bay there, start making things look the way they should, and you want to make some good performance, go ahead and stick around. I'm gonna show you guys exactly what tools you need in just a second and then I'm gonna walk you through the entire install step by step. All, right guys before we start installing our intake, we'll need to grab a couple of standard drive ratchets and we're also gonna need an eight-millimeter and 13-millimeter socket. Lastly, you're going to need a five thirty-seconds Allen key, a measuring tape, a Philip's head screwdriver, and a cutting tool or a pair of snips. Optional but helpful tools include a long extension and some spray lubricant. All right. We're starting over on the driver side here. We're gonna disconnect our intake temperature sensor, just press down on it like so, then we're going to loosen the clamp that secures the intake to the throttle body using an eight-millimeter socket. All right. Next, we're gonna disconnect the breather hose located back here behind the cover, just press on it on the bottom and the clip should release like so. All right. Next, we're gonna disconnect the clamp here that secures the tube to the factory airbox. You're also gonna need that eight-millimeter socket. All right. With everything disconnected you can pull the factory airbox out of the vehicle, it's just held in with a couple rubber grommets so you don't need any tools for this one. All right. With our airbox out of the way we can also remove the factory air tube. Now it might be held on with some rubber grommets in the back, you just gotta kind of wiggle your way out of them. All right. So now we have our factory air system removed you can see what a nice upgrade the new K&N system is in terms of aesthetics, right? We're ditching all this ugly plastic, we're getting rid of this big ugly box here. We got a really nice black powder-coated heat shield. You'll be able to see the conical filter in there doing its job underneath the hood with the motor on and you got this really nice intake tube here made out of aluminum with a nice silver finish on it. So overall very old school classic look from K&N and rightly so, right? We definitely don't want any boring stuff underneath the hood. But before we ditch all this stuff we have to do a couple of things, we have to pull a rubber grommet on the bottom of this, transfer it over to our new heat shield and we also need to make sure we rescue our intake temperature sensor. All right. Once you've rescued that grommet and the temperature sensor you can discard the factory air system. Next, we're gonna assemble our heat shield here. You got this fresh air scoop that you need to secure to the primary box. To do that you're gonna grab four of the Allen head bolts provided in the kit and you're gonna need one of those crushed washers and flat washers for each one. Then you're also gonna need an Allen key, specifically a five thirty-seconds. All right. Now we have our heat shield assembled, we're going to install the adapter for the air filter next. If you hadn't guessed why you have two extra screws, well, they're gonna fit inside these little threaded holes right here so you're also gonna need that five thirty-seconds Allen key that we were just using. All right. Now that we have our air filter adapter in place we're gonna cut our edge trim piece here into two sections. One's gonna be 29-inches and one is gonna be twenty-three and a half inches. All right. With those trim pieces cut, you could start applying them to the airbox. The long piece goes on top like so and the small piece is gonna encapsulate this cold air scoop. All right. Next, we're gonna install that rubber grommet we took from the factory airbox in the hole here on the bottom of the new one. This is a squeeze so it's helpful to spray it down some spray lubricant or some WD-40. Once that's in place you can install your air filter. You're gonna need a large clamp in the kit and you're also going need that eight-millimeter socket that you've been using the whole time. All right. Now you can finally put your heat shield aside, we're gonna do a little bit of work to our new intake tube here. We have to install this little fitting here for our breather hose. It's gonna go on the threaded holes right here. Now, these are plastic threads so you want to keep them hand tight. You don't really wanna use any tools on these so you don't strip them out. Then once you got that fitting in there you can install your intake temperature sensor in this little rubber grommet right here. All right. Now our air tube is also ready to go. The last thing we have to do is set up our new breather hose. Now they provide a really small clamp in the kit. You'll need to Philips head screwdriver for this guy. Go ahead and throw this barbed fitting in the end of there and secure it with that clamp. All right. So we turned a bunch of hardware and parts into a couple of primary components. First thing we're gonna do is throw our new airbox in place. It does secure with some of the bolts inside the engine bay so you're gonna need a 13-millimeter socket. I'll show you guys where those go. All right. So, before we throw the airbox in you're gonna be pulling these two 13-millimeter bolts. Again you'll need that 13-millimeter socket. All right. Now you can throw your airbox in. Make sure the cold air scoop lines up with that hole inside the fender and also make sure that rubber grommet you just installed lines up with the little plastic stud underneath then you can throw those bolts back in place and tighten them down. All right. With the airbox secure, we're gonna throw on our intake tube here. It's helpful to have the intake slide on to the airbox side first because that coupler has a little bit of flex in it. Once you get that flush, go ahead and slide the other end onto the throttle body and tighten down all your clamps with that same eight-millimeter socket. All right. While we're over here we're gonna reconnect our intake temperature sensor and we're also going to throw on our breather hose extension. So once you got those final clamps tightened down that'll wrap of this very easy install and that also wraps up my review of the K&N Series 77 cold air intake fitting your 3.6-liter powered Ram 1500. I'm Travis, thanks for watching, and for all things Ram, keep it right here at

        Great upgrade

        This has been a great upgrade, horsepower gains may be small however if you know your truck you’ll feel it. Paired with pedal commander was a great idea as well. Took time night before to put major components together and that was pretty simple, install took less then an hour once I popped the hood.

        Nice addition

        Had this on for a couple of months and I'm very satisfied. Install took right at an hour and everything fit perfectly. Have noticed a slight increase in MPG and throttle response.

        WORTH IT

        I was looking for a little more power out of my truck and this was perfect, I have a Magnaflow side exit exhaust on the truck as well, with the intake now it sounds much better when i get on the gas especially at full throttle. It was a direct fit and Looks way better than the factory plastic air filter box and engine cover, worth every dime.

        Great Product and Easy to Install

        Product works great and was easy to install. It gave my 3.6L a bit of a rumble that ive been looking for and has helped with throttle response. Little on the pricey side, but overall very happy with the purchase. With light mechanical experience, install is quick and easy, took me a little over an hour doing it outside in the cold.

        At first I wasn’t seeing any improvement, but after about a month I went from 19.3 mpg to 22.2 mpg. It sounds great and was very easy to install.

        Easy intall

        Super easy install, fits like a glove in my 2018 RAM 1500. Some hardware was missing, but the issue was easily resolved by calling the number on the instruction sheet. KandN over-nighted the hardware, and UPS dropped it on my porch the next day.

      5 Top Rated Questions

      Does anyone know if when the cold air intake is installed does it have any effect on the vehicle/engine warranty? And does the engine need to be re-tuned after installation?

      • This will not require a tune. We are unable to advise regarding your truck's warranty, as the dealer makes this determination directly. We recommend consulting with your dealer before modding your truck with an intake. The Magnuson-Moss warranty act basically requires the dealer to show proof a product caused the issue in order to void the warranty, but no one wants to have to argue with the dealer.
