COBB Cold Air Intake System Focus ST 2013-2014 is rated 4.8333 out of 5 by 12.
Rated 5 out of 5 by from Great Intake! Very pleased!! Great sound, and is way better than the cramped stock stuff. Make sure you read the .pdf instructions and grab some Silicone spray. When you're done, make sure the wipers went back on that the correct angle. If it rubs on the fuel line, a slight change in angle on the line (it should be parallel with the ground) is the difference between rubbing and perfect clearance - thanks to Cobb for figuring that one out. (I'd also like to add that there's MUCH more sound and power with an AccessPort)

Rated 5 out of 5 by from COBB Focus ST Intake I installed this today. What a pain in the neck it was to get the clamp at the turbo undone. FYI, get a box wrench/ratchet 7mm or else it'll be a pain. I got the intake in easily other than that. The video doesn't really discuss when you remove the stock intake you must remove the rubber adapter that's also on the turbo inlet pipe. Other wise sound item and very pleased with it.

Rated 5 out of 5 by from Amazing I love my ST and I know Cobb makes awesome performance parts, so it was not a doubt in my mind to get this intake. After I put it in I can feel the power difference. I can also hear the turbo so much more. If you love your Focus ST then I would recommend this intake!

Rated 5 out of 5 by from Excellent Product Installed this on my right hand drive Focus ST. Looks and sounds great. This is a real quality product, and fast shipping. On right hand drive the intake can hit the Brake Master but with persistence it was done.

Rated 5 out of 5 by from Easy Upgrade/Brilliant results Bought less than a week ago, got it in last night, installed in an hour. Couldn't be happier with the results. Cobb makes a great product and CJ Pony Parts has the best videos to help with the installation of all their products. Both of these companies have gained inspired loyalty from me already!

Is there any word yet on whether this will fit the 2015 ST ?

Asked by: CAL ST
According to Cobb's website, this is NOT fit a 2015 ST. They're developing a new one that will.

COBB Cold Air Intake System Focus ST 2013-2014 Video Transcript
By Bill Tumas: Last time with our Focus ST project car, we had it on the dyno, where we saved some good gains from our Borla exhaust system. Now that we've improved the exhaust, the next logical step to make in horsepower is going to be to improve the intake system.

Today, we're going to remove the stock air intake and replace it with this cold air kit from COBB. COBB is well known in the sport compact market for their excellent finish. Their cold air kit for the Focus ST is going to include the cold air piping itself, silicon couplers, all necessary hardware, and reusable green air filter. They also give you a nice collection of swag, including a license plate frame, a couple of decals, and even a mail-in postcard, where you can get a body-color decal for your cold air kit.

For this installation, you'll need a 3/8th ratchet, short extension, 15mm socket, 12mm deep socket, 10mm socket, T30 torx bit, 1/4-inch ratchet, a couple of extensions, 8mm socket, 7mm socket, and a small flat head screwdriver.

Our COBB cold air kit is going to replace the factory piping that goes from the turbo behind the engine and then over here to the factory air box. We're going to start by removing the engine cover and then the cowl cover, to give us easier access.

To remove the upper cowl cover, we've got to start by removing the wipers. Little rubber covers, you simply pull up on these and remove the nut underneath. Once the wiper's off, we'd start with the lower cowl with the two torx screws, one located on either end.

Next piece of hardware we've got to remove is underneath these covers. They simply pop straight off. Remove the single bolt on each side. Once the hardware's out, we can remove the cowl.

Now we'll start the factory air intake tube removal by removing the mounting stud here for the engine cover. Just remove the bolt right next to it that holds it to the engine cover. Now the bolt to the throttle body.

Now remove the rubber coupler from the box here. Sometimes it's easier to take the battery cover off to get our socket in a little bit easier. Once we get that loose, we move over to the turbo side. The clamp on this side is going to be at the bottom of the air intake tube all the way down by your turbo. Pretty much, right down here, in the back of the engine. Small screwdriver or a small ratchet, you should be able to get down in there.

Now we've got to remove the hose from the back of the intake before we take it off. Disconnect this hose here so we have a little more room. Remove our stock air intake pipe. Here you see the turbo. Now, I'm going to take the silicone reducers supplied by COBB, put the small end on the turbo itself.

Put a little bit of silicone spray inside the tube to make it easier. Put it down to the place onto our turbo. Make sure you put the clamp on first. Make sure it goes all the way to the bottom and it's seated. Slide the clamp down over the end.

Put another one of the larger hose clamps over the pipe before we install the actual three-inch COBB pipe. Again, I'm going to spray a little bit of silicone on the end here to make it go easier on the silicone coupler. Now, we'll slide the clamp into place and tighten it down. You don't want to tighten it all the way at this point. Just get it snug around the top of the silicone coupler. We'll come back and tighten everything down once we've fitted the rest of the kit.

Now we'll put our last two hose clamps on the last silicon coupler, here, and connect it between the main pipe and the air box. I'll go back and tighten the clamp on the turbo side. We have the pipe adjusted so that everything's fitting pretty good, but to get the bolts in here, we're actually having a clearance problem with the fuel line. That can happen with some installations. In that case, I want to use the bushing up front, just to lift this up for extra clearance.

Put the factory spacer underneath. Then reconnect the line we disconnected earlier. Reinstall the stud for the factory engine cover. Now reconnect the hose on the back of the intake, and move on to the air box. Now, remove the four bolts that hold the air box cover on. These will stay attached to the cover, so just once you have them unthreaded, just let them sit there.

Now, remove the factory paper filter. Now we'll install our reusable filter. It comes with a clamp. You really don't need it because it's such a tight fit in here, it's not going to go anywhere. Now, reinstall the cover. Now we can reinstall our cowl. Covers can go back on. Install the wipers. For the last step, we'll reinstall our engine cover, and our installation is finished.

We installed the white decal COBB provided, but, again, they do give you this postcard that you can mail in and get an actual body-color decal to go on your cold air kit.

Now we'll start it up and see how it sounds. Wow. That actually made a big difference. You can really hear the turbo through the intake now. Even the recirculation valve's a lot louder. Now let's get it out and take it for a test drive.

You can definitely hear the intake when you're driving, especially the high RPMs. It's not as noticeable as it was when we were revving it up in neutral, but you can definitely still hear it when you get on it. Feels good too. Car's really responsive. Can't wait to get it back on the dyno.

Our COBB intake fits great, sounds amazing, and by the seat of the pants, feels like it's making some horsepower too. Installations should only take you around an hour. Should be back on the road in no time.
