      Video Review & Installation

      Hey guys, Joe from ExtremeTerrain and today we're going to be working with the K&N Series 77 High Flow Performance Cold Air Intake fitting all 2016 and newer 3.5-liter Tacomas. Now, this is going to be perfect for any Tacoma owner out there looking to get a little bit more performance out of their 3.5, horsepower torque, throttle response, induction noise, with a high quality and reasonably priced cold air intake. This kit features a high flow red lifetime air filter, which is not only going to look good in the engine bay, but it's also washable and reusable. So, if it does get a little bit dirty you could take it out, clean it, put it right back in and be good to go. We also have a free-flowing and high-density aluminum intake tube featuring that polish finish and the K&N logo right up front. Now, what that's gonna do is clean up some of the turbulence in the incoming air, promote a nice and smooth flow compared to our factory one which we're gonna get these two side by side in just a minute here, that's going to allow that air to come in smoother and cooler. Now, we're gonna show you how to install this in just a second, we're gonna put the Series 77 right next to our factory cold air intake, and you're gonna see just how much of a flow improvement this one is going to be, more free flow, less turbulence are all good things. We also have this heat shield out here that's going to keep the filter shielded from any warm air in the engine bay. And you know, cooler air means more dense with oxygen, more oxygen for the engine to burn is what's going to give you horsepower. This is going to be a complete drop-in replacement. There's no modification required, there's no computer retuning required. So, you're gonna see some of that horsepower torque, throttle response and induction noise, all without touching any of the computers in your Tacoma. So, this is going to come in in terms of price right around that $300 mark. Now, the market for cold air intakes on the Tacoma is going to be pretty tight, the range is usually $250 all the way up to $450. There's some outliers out there that do cost more but that's usually a good operating range. This coming in right at $300 puts it on the lower side to begin with. But if you were looking for an even more budget-friendly option, K&N offers a Series 63 which is basically going to be a very similar design, it just deletes that aluminum intake tube and replaces it with a plastic one. Before we move on to the install here, I did just wanna make a quick note. This kit is not CARB certified, so if you do live in one of those more emissions restrictive states, take a look, there's plenty of other intakes on our website that do feature CARB numbers. Now, with that being said install is going to be pretty easy, definitely something you could do in the driveway with just some basic hand tools. I'm gonna give it an easy one out of three wrenches on our difficulty meter, should take you at most two hours to get this hooked up to your Tacoma. So without any further ado, let me show you what you'll need and how it's done. Tools required for this install are going to be an impact gun or ratchet, small extension 12, 13, 10, and 8-millimeter sockets, 3-millimeter Allen key, 4-millimeter Allen key, 19 and 10-millimeter wrench, scissors, wire cutters, Phillips head screwdriver and a trim panel removal tool. So, for the first step of our install here, we're going to peel back our engine cover, pry up at the front and that'll pop right off. Now, that's going to reveal two things. First off the clamp around our throttle body, we're going to loosen that up with a 10-millimeter socket. It's also going to reveal the crankcase ventilation hose. We're going to pinch the clamp around that and just pull that hose off as well. Now as we move down our intake that's going to bring us to our mass airflow sensor harness. This is going to pop off, just pinch the back of that clip, that'll slide right off, but it is still connected to the intake itself. So, we're going to pry back here and release that. It's also held on with a Christmas tree clip right here, I'm gonna use a trim panel removal tool to get that out of the way.Continuing to move down here, the top half of the airbox is held on with these two clips, just peel back to release and you wanna make sure that those bands come out from underneath. That's gonna release the top half and we can pull that whole thing out. And it's obviously going to reveal our paper air filter here, we're going to pull that out as well. Now, as far as the bottom half of the box here goes, it's held on with two 12-millimeter bolts inside the box. You'll probably need a small extension to get to those. There's also one hidden back here on a foot that's holding it in as well. So we're going to hit all three of those and pull this out too. So, now we can move to the table, start assembling our K&N, we're going to start the airbox side and attach this coupler right here to secure our air filter with these 4-millimeter button head bolts included in the kit. Next up, we're going to attach this mounting bracket, it's going to go in this hole right here in the corner of this heat shield that's going to attach using the longer 10-millimeter bolt in the kit, a flat washer, and then the small 10-millimeter nyloc nut also included in the kit. Now, this bracket is slotted on one side and circular on the other. We're gonna make sure that that's slotted and meets up with our heat shield. Next, we're going to apply this rubber seal right here. This is going to go right on to this outer edge of our heat shield. They do give you just a little bit extra, so I'm going to use some wire cutters to snip that off. That's going to be pretty much it for our heat shield. I'm gonna leave the filter off for now obviously, we're gonna need to get to the floor later when we secure this to the truck. So, we're gonna put that aside, move on to our intake tube here. I'm gonna start with this fitting, this threaded, goes into this threaded hole right here. I'm gonna tighten it down with a 19-millimeter wrench but be careful when you do this. This is only plastic and it doesn't need that much torque. Good rule of thumb here is just get it hand tight, give it quarter turn.Next, we're gonna move on to this hole right here in our intake tube. That's gonna be for our mass airflow sensor. All we're going to do is pull it out of the factory one here and drop it right in. Now to get it off our factory intake tool, we're gonna need a Phillips head screwdriver, it's held on by these two screws right there and right there and to get it in K&N gives us some new hardware and these are going to tighten down with a 3-millimeter Allen key. Now, we're just gonna drop this in and the screw holes are all set. There's only one way this sensor is going to fit, so no chance of getting it wrong. Now, also when I pulled this out, the gasket underneath there did come with it, you wanna make sure that stays with the sensor. Now we're just gonna combine our two pieces together. Now the coupler for that goes in between the heat shield and the intake tube is going to be smooth around the outside. And this one which we are gonna get started on this end of the intake tube will have that little hump in the middle of it, this side is going to be for throttle body. Now all these clamps are the same size, they all get tightened down with an 8-millimeter socket. Now we're gonna hop over here and do the same thing for this side. Again, half of that coupler is going to be toward the throttle body. So, now we're just about ready to drop our Series 77 in our Tacoma, but before we did, I just wanted to pop that filter on there so we could get the full kit and compare it to that factory intake. We're gonna start at the filter and work our way back. So, this is going to be K&N's high flow red filter. Now, this is going to be washable and reusable. So, on top of looking good, you won't have to buy more paper filters like that one there, and you're also going to get an increase in flow as this is going to be again that high flow filter. Moving down to this heat shield design here. Unlike the factory, which is that ugly closed box, you get to see some of that factory intake but at the same time, keep it shielded from that warm air in the engine bay, just like our factory box. From there, the intake tube is going to be a high-density free-flowing aluminum that's going to be lightweight and strong, but again, also free-flowing unlike the factory one here, which features this flex pipe. All that's there for really is to make it a little easier on Toyota when they're installing the intake at the factory. After that it's just going to create turbulence, not with our new K&N system it's going to be smooth throughout sporting that polish finish and that K&N decal right up front. We're also completely deleting this big factory sound box right here. Now, all that's there for is to take away some of the induction noise, make it a little bit quieter in the cabin of your Tacoma. With that off of there, you're definitely going to be able to hear a little bit more induction noise out of the engine and on top of that, by getting rid of that we're also going to be cleaning up some of the turbulence. So, without any further ado, I'm gonna take this filter back off, we'll take our Series 77 back to our Tacoma and start to get this thing installed.Before we drop in our new intake tube and heat shield, there's actually a couple of rubber isolators we're going to need to install so our box can mount up cleanly. Now, this one right here with the female end is going to go in this hole right here. And as you can see, they're not supposed to thread down all the way. There's another one identical to that, that's going to go in right here next to this wiring loom. And this one is male on both ends, that's going to go in a threaded hole right here by our power steering fluid. Now, we're just gonna drop in what we built on the table and get that coupler started around our throttle body and at the same time, get our airbox lined up. Once we have this lined up, we're going to tighten it down with the two 10-millimeter bolts to those female isolators and a 13-millimeter nut on that male threaded stud. And again, these two bolts in the airbox are going to be 10-millimeters. Then we're gonna reach all the way down here in this tight spot. Then we can drop in our new air filter and again, you can tighten this down with an 8-millimeter socket or a flathead screwdriver.Now, all we have to do to wrap this up is plug back in our MAF sensor, get our crankcase vent hose connected again and tighten down the clamp on our throttle body 8-millimeter socket or a flathead. And finally, if you want you can pop back on the engine cover that meets up with a hinge in the back and then just comes down onto the studs and presses in. And that is gonna do it for my review and install of the K&N Series 77 High Flow Performance Cold Air Intake, fitting all 2016 and newer 3.5-liter Tacomas. Thank you for watching. I'm Joe.
