Mishimoto Performance Cold Air Intake Kit Focus RS 2016-2018

A well designed cold air kit is a basic performance upgrade that could be beneficial to any vehicle, especially a turbo-charged car like our Focus RS. We're looking to make a little more power out of this car and have a little more fun with it, so today we're gonna install this Mishimoto Cold Air Intake. This kit is a direct bolt-on, includes all necessary hardware. Mishimoto claims 12 horsepower and 15 pound feet of torque with no tuning required.

For this installation you'll need a 1/4" ratchet, 7mm socket, 8mm socket, 10mm socket, 13mm deep socket, an extension, 10mm wrench, and a 4mm Allen key. Our RS previously had a cold air kit installed on it, so what we're gonna do is we're gonna show you some footage on how to remove the factory one, then begin the installation to Mishimoto. Our cold air kit's gonna replace basically this section right here, so we're gonna start by removing our engine cover so we have a little more access. To remove this pipe we have to remove this clamp here, this one down here at the box, and this bolt holding it to the engine. Okay, now we're gonna remove the tube. Disconnect this hose. So we'll disconnect the sensor. Pull the little plastic plug off, and carefully remove the airbox just by lifting up.

Begin the actual installation on our table. We have a little assembly to do with the box. The first thing you want to do is flip it upside down on the shelf section here, grab one of the larger screws with a lock washer, and thread this on. Just get it hand-tight. This will have a little bit of a movement up and down, so just get it hand-tight for now. Then you want to grab this bracket with a round end here in this little slot, this will go right here. And again, grab the second of the larger bolts. Leave that loose enough to move around, as well. Gonna grab this longer bracket and on the side here with the two holes -- the inlet duct -- just gonna go right here next to the bottom hole. Just get it snug. Now on the bottom of this bracket, facing down, we're gonna install another stud. Again, just snug; leave it loose for now so it moves around a little bit. This bracket here with the slot, this is gonna sit right inside the lower air duct here. Secure it with the supplied hardware.

Now we're ready to install the inlet on the car. You want to grab the inlet pipe itself and the smaller clamp, and make sure it's orientated so you can get to it when it's on the car. Now we're gonna fish the inlet tube down there and connect it to the turbo. Then get in there and tighten it down. We're ready to install our airbox. There's a couple little pieces we have to install still, though. These two pieces are gonna come off of your stock airbox. This is a lower duct, this is just one of the mounting pegs. The mounting peg is gonna go right here on this stud, just slide it right on, and the lower duct is gonna go down here with this bracket. What you want to do is lift the bracket up; install the duct so the bracket clamps it into place.

The box is gonna mount in the same location as the stock box, using the three factory locations. You got one down here, one here, and then the factory one up here. You want to make sure they're all seated, then we're actually gonna tighten the brackets down and get the box where it belongs. With the box secure, then we can rotate this into place. Then tighten that down, as well. We're gonna put the airlet sensor in. We'll install the cable clip, there's a little notch on the back. Now we're gonna grab this bracket here. Again, use your original rubber grommet from the factory inlet tube, and it'll insert through the top. Then you're gonna screw it to the bottom of the tube. And again, leave it loose. We want to make sure we can adjust it when we get it in place. I'm gonna put the clamp back here on the inlet hose. I'm gonna put the intake tube into the airbox and sort of shimmy it into place. Connect to the tube.

Okay, now we're gonna install this bracket here, over the factory stud. Now we're gonna reinstall the factory nut on the stud. You line that up, install a mounting stud for the cover. Gonna bring the warm air clamp up into place here on the inlet tube. With the tube in place, I'm gonna reach behind it here, install the PCV line. Make sure it clicks. Now we'll grab the vacuum line, put the rubber grommet in the back of the Mishimoto tube, flip it in up top here, then plug it in the valve cover. Now we're gonna line this bracket up over here and reinstall the factory bolt. Then, using a 10mm wrench, tighten the bolt underneath. Coming back over on the airbox side we're gonna plug our sensor in, then install the other duct. Now we can install our filter. Now you want to make sure all your hoses are tight with everything in place. First we'll start with the hose up here, and then tighten the hose at the turbo.

Now the last part of the installation is to install the airbox lid. Just get all the bolts started before you try to tighten anything down. Reinstall the engine cover, and your installation is finished. Let's fire it up and hear how it sounds. As we've come to expect from Mishimoto, the cold air intake kit for the RS, it fits really well and it looks great under the hood, and should make some power, as well. Installation's not terribly difficult, figure about an hour to an hour and a half; you'll be back on the road in no time.
