Can I use this kit but still keep my green filter or do you have to use the filter that comes with the kit? Newbie here ;-)
Great product I love the sound and the excellent throttle response. I noticed that my filter is getting dirty, as to be expected, how do I clean the filter?
Will this intake go well with the Borla Cat back i have on my 2014 Focus ST?
how much horsepower will this add?
I saw your response about the Roush vs. Cobb for CAI in a 2015 Focus ST. When I contacted Roush they said they don't have one for 2015 models currently. Do they have to wait for approval from Ford or something? They say theirs doesn't void warranties.
I need some clarification. I asked a few days ago if the Cobb CAI was compatible with the 2015, I was told it wasn't and that Cobb was modifying to fit the 2015. If this one fits 2015, why doesn't Cobb's fit. Is this item a verified fit?

The Roush kit comes with everything necessary to install on your Focus including this inlet tube which comes in black. We actually powder-coated ours white to match our car. Comes with the silicone couplers, hose clamps, seal, a new box and a reusable filter. For this installation, you need a quarter inch ratchet, 7 mm socket, 8mm socket, 12mm deep socket, extension, flat head screwdriver, flashlight and scissors.
Our Roush cold air kit is going to replace our air box lid with a high flow lid, we'll replace this tube here as well while still keeping the stock mass air meter. The first step is to remove our engine cover. Simply pull straight up and put it aside. The air box lid is held in place by these four bolts here, so we'll remove our stock paper filter, and we're going to remove the factory clamp for the rubber boot here and the other one on the side.
I'll separate it from the cam cover and remove. Now we can remove these two mounting bolts here from the cam cover to get the rest inlet tube off. This is your normal 8mm, but for this we're going to need a deep socket and you want to make sure you keep this, because this is actually one of the mounting points for your factory engine cover and you will reuse it.
I'm going to disconnect the PCV from the back of the tube. Simply squeeze them together and push backward. The last plan for removing the stock air tube is kind of hard to see but it's down behind the cam cover, it's the same size as the other one. Simply remove it and pull the whole tube off.
You want to remove the steel inserts from the factory air tube, you're going to use two of them in your new Roush. Simply push up on the metal insert, pull the insert out and then remove the washer. Now, we'll install the inserts we just removed on to our Roush inlet tube. Now, we'll install the coupler onto the tube here, and install the supplied clamp.
Now, we'll connect our cold air kit to the factory lower tube on the turbo, this will be the hardest part of the installation, since it's so far down the engine bay. You'll notice we actually put some towels on top of our engine to protect our powder kit, we do the same thing with the stock paint as well.
I'm going to tighten the clamp up by hand just to get it to hold before going there and tighten it down for good. We'll reach behind and connect our PCV to the inlet, pull our towels out, now connect to our meter, now tighten down the factory clamp. You want to install the Roush supply washer underneath this and then reinstall the factory bolt.
We'll reinstall the factory mounting stub for our cover. We'll reinstall the bolt to the throttle body, we'll then install our new filter. Now, we'll install the factory screws from our factory lid into our new Roush open lid and tighten everything down. Now, install the seal which snaps into place. Now, cut off the excess. Our last step is to reinstall our engine cover and our installation is finished.
A Roush cold air kit is definitely a lot less restrictive, so it should pick up some horsepower without any additional tuning necessary. Installation should only take you around an hour and you'll be back on the road in no time.
