K&NCold Air Intake System: High-Flow Air Filter, Increase Performance & Towing: Compatible with 2010-2024 Toyota: 4Runner, FJ Cruiser, 77-9034KP

So far so good. I just installed the chrome version of this on my wife's 2018 4SkinRunner and it fits perfectly. No modifications what-so-ever were needed. I'm not sure why Amazon and others say this is not designed for the 2018 Toyota 4SkinRunner and will not fit, because it did fit and it fits well. The one thing that I had seen and read about prior to getting it was having to redo the looming on the MAS sensor where it exits on an existing bundle, but absolutely nothing was required. If you do get this cold air intake, when you are finished, there will be nothing that the loom bundle and MAS sensor are restrained to as before installation. It's not that big of a deal, but what I did was take some zip ties and secure the loom bundle down to an existing bracket on the manifold. It worked perfectly, but not necessarily needed.What took the longest on the install was simply unscrewing and unhooking everything in order to get the engine bay properly outfitted to install the thing. Once installed, you wonder what all of the Toyota stuff on the intake was for. There is a lot more room without those "pod" like things that are connected to the OEM intake tube.K&N really thought of everything when they designed this. You have to remove the horn which is held on by one bolt on the fender wall, remove one bolt that holds the power-steering reservoir on, and completely remove the air pump which is held on by three bolts, in addition to the original air box. There are a few electrical bundles to disconnect first and a couple of hoses to pull off, but it's really simple.Once you've got the K&N airbox bolted in place of the original; the horn, PS reservoir and air pump go back exactly where they were, but slightly altered to accommodate the K&N equipment. It's easy, trust me.The 4SkinRunner is my wife's vehicle so I don't really drive it that much. Occasionally, I'll take it to Tomball which about 15 miles away and I'm lucky if the mileage indicator will increase even a 1/10 of a mile with easy driving by the time I return. When I finished the install, I had my fingers crossed that everything would work ok and took it out for about a 6-7 mile loop around the area. I was flooring it, goosing it and basically everything that you don't do to conserve gas. When I started it out, the 4SkinRunner showed that it was getting 16.3MPG. (It's been on 16.3 for weeks.) Before I even got back it had jumped to 16.4MPG.The thing I hate most about the V6 4SkinRunners is how slow they are, coupled with horrible gas mileage. Of course, you don't buy one of these if you're concerned about the mileage; right? The fact that it jumped a 1/10th with what I was doing, has really got me hoping that there is much more in store in the mileage department on this thing with "normal" driving. And that, my wife will do.Does it get up and go any better? Well, it's hard for me to say since I don't dive it very much. However, I do know that it's fairly slow, but man, when I floored it, it sure seemed to get up and haul ass much better than what I recalled beforehand. I'm not sure if it's psychological or not, but it sure seems quicker/faster. I even tested it to get around some slow jerkoffs and it seemed very good at getting around them.At minimum, they are going to hear you, and you'll hear yourself too. It's friggin' loud and I installed the top cover to the filter which is optional. If you like a roar, you're going to love this. My wife will not like this beast that is lurking under the hood and has no clue about, until the first time that she puts her foot into her 4Skin machine. (Heck, she might come home and be all over me though.) If you're just doing normal driving, the sound is no different than stock. That's why I say she's going to get a huge jolt the first time she drives her right 6" Christian Louboutin into the gas pedal.So, only time will tell if this increases the mileage or not. I'll let her tell me if she feels that it has more get up and go. Of course, we could have bought the Lexus version which is either the GX460 or GX470 for a a lot of extra cash and gotten a V8, but you have to like the way the vehicle looks also and neither of us like the way the Lexus version looks, even though our other vehicle is a Lexus. The Lexus version is more up to date also, HID lights, etc., but it doesn't look as good as the 4SkinRunner, in our opinion.Back to the installation. If you have hesitated to get this due to not knowing if it will fit your 2018 4SkinRunner, don't wait any longer, because it will fit.The one thing that I would stress the most, is to make sure that you have a ratchet wrench with an extension, at least 6". Longer would be even better. If you decide to start and don't have the correct tools, you're going to be very irritated. Just go to K&N and look at the instructions and make sure that you have the few tools required. It's just that ratchet extension which is the most important.In addition, refer back to the parts and diagram list when going through the instructions, because the instructions are not good at all with which bolts, washers, etc. to use.Spend the few extra dollars and get the chrome version. It's looks fantastic.Cheers!

It works. I know people say that intakes don't really help anything, because Toyota already has cold air intakes, but it is a difference that I can feel.It is very noisy, if you don't want the hear that intake noise, don't buy it. I like that sound.It's not an easy install, some reviewers said that it trips CEL and it doesn't run. I would imagine that it is because they missed something here or there on the install. Probably the mass air flow sensor. This is the third intake I have installed on a car and I am happy with all of them. No trouble lights.Be careful with that MAFS. Dirt and alignment affect it.

The K&N cold air intake for a 2016 4Runner does not fit as perfectly as indicated. The parts are there and are of reasonable quality. The instructions were written by a not too savvy desk-jockey. You will need to use the online video, the provided instruction sheet and the installation instruction online to have a hope of figuring out your installation. The nuts, bolts and washers, referred to by K&N as "the provided hardware", make no reference as to which of the nuts and bolts and washers are to be used for the various parts of the installation, that is your prerogative, good luck with that. The crank case vent is set too high on the intake tube which prevents the engine cover from being installed. You will need to cut an appropriate piece from the engine cover to provide a clear fit. The heat shield cover does not fit as indicated so I needed to leave one of the bolts out. K&N advise the heat shield cover may be left off, that begs the question of how the cool air remains cool when it will suck in hot air from the engine compartment. After making the engine cover fit I started the engine. The engine now has a clear roar to it. Took for a test drive and immediately saw a noticible increase in pickup. When I put my foot down a bit harder on the accelerator there was a roar and a faster pickup. With regard to mileage, the jury is out, we shall see.OK folks, I have just finished 100 mile test for mileage in the 4Runner. The highway run of some 50 miles gave me 20.4 mpg whereas before installing the K&N my best was 17.9 overall. On my run back home through towns with stop and go traffic my mileage was 21.6 mpg. Now this may be predicated on the way I drive. Most of my driving was in the green, that is how I drive. If you put your foot down hard you will experience a considerable roar - like a mustang on heat - and you will accelerate quickly off the mark. So acceleration up and mpg down.To sum up, the pundits who say there is no advantage to a K&N CAI may be dependent on whether your vehiCle is an SUV or a car. All I can say is that I have proved the positive for my 2016 Toyota 4Runner. Quite happy with the results. Take care.
