We took the Fiesta to the dyno a little while back and thought that it needed just a little bit more power so we wanted to install some performance parts. We looked to mountune to get the job done! We have done a lot of research into all of the options available for our little Fiestas and mountune seems like they have the most experience and knowledge about this platform. They have been modifying The Ford Focus and Ford Fiestas for years.
We gathered up some of the parts we have here, in stock and installed them. We got the quick shift bracket, the intercooler and the intake! Since we were installing these parts, we wanted to give you guys fairly comprehensive installations guide so you have something to use for informational purposes when installing your parts. We will continue to give you guys these informational how-to's as we build our Fiesta. We look forward to giving all of you guys some great information and have fun installing these great products on this car.
As we go along, we will give you some before and after data that we observe on our particular Fiesta (your experience may vary). We are excited to see just what we can do with this car, both on the track and on the dyno!
Here's a shot of everything we are installing this time around. From left to right we have the front mount intercooler, then the intake, and lastly, the quick shift bracket all from mountune performance.
In this particular write up, we are installing the mountune performance intercooler. When we first looked at installing this, we looked into the advantages of having an upgraded intercooler on this car. We saw that we aren't going to get much benefit without a tune at first, but the colder charge air temps will help keep detonation in check while we race it on those hot days at the track.
This is a little blurb from mountune about the intercooler
The Mountune Performance intercooler for the Fiesta ST includes everything you need to optimize and maintain the performance of your ST.
Using a 7-row extruded tube and fin core, the mountune intercooler gives a marked improvement in both Air Charge Temperature (ACT) and pressure drops, ensuring optimum charge air temperature and therefore power, is available from the excellent 1.6-litre EcoBoost engine.
The mountune intercooler has also been packaged to retain all of the extensive cooling pack features found on the ST as standard, ensuring optimum cooling is achieved.
Each intercooler is powdercoated to protect against oxidization and is hand-made and inspected in the UK; combined with the warranty benefits, this is the must-have intercooler kit for all discerning Fiesta ST owners!

Here's a nice shot of the intercooler itself. It is a very nice piece, with smooth transitions from the core to the couplers as you can see.
First thing we need to do is gather up our tools and start taking off the front clip. There are a few little screws and clips in the fender wells on the driver's and passenger's side. You can see three of them here.
Start by screwing the phillips clips out, then removing them completely as shown here
Then, just remove the torx screws.
Take the same three off of the opposite side fender well, now we can move up top, we'll need to remove the headlights to get to some other clips/screw/bolts. This is VERY easy; take this t30 torx bolt out here
Now we have a t30 torx bolt and a phillips plastic clip to remove up front. Simply remove the torx bolt and unscrew the clip, then remove it completely.
Once you get the bolts/clips loose, you can remove the headlight, exposing the wiring clip on the under-side of the assembly. You can see it here, all you do is squeeze the top/middle of the clip and pull it out.
Now we can remove the whole headlight assembly.
There are a lot of clips on the front of the car, but we don't have to worry about removing all of them, just these two.
Back in the fender well, you can access the bottom and three bolts that hold the front clip on the car. You can get to this one from the fender well, the other two you will have to get from up top. They are 8mm bolts. These will need to be completely removed in order to get the front clip off of the car.
From the top side, you can get a pretty good view of all three of the bolts you need to remove.
Here's a shot of them removed.
Now that they are out, the fender should separate from the front clip like this
Reaching in where you removed your headlight, you can see the back side of the foglight assembly. You will need to unplug these in order to remove the clip from the vehicle. Simple enough, it's just a squeeze clip, like the headlight.
Now, back to the underside of the car to remove some screws and clips. Here you can see the two screws and on clip on the right of the image, then there is a retainer on the left that just pops out when removing the clip.
One screw in the middle.
Then the same screws/clips on the other side.
Now, gently, and carefully pull the front clip off the front of the car, making sure that you have all of your clips and bolts and screws loose and set it aside.
Here, we can take our first look at how difficult it will be to remove the factory intercooler. It is pretty easy, as you will see.
First thing we did was remove the intercooler hoses off either side of the intercooler. They just take a flat tip screw drive or a 7mm wrench to get them loose
Once they are loose, they pull off, it takes a little bit of effort due to the grooves in the intercooler, but they will come off.
Next, we can do the other side. Same thing, loosen the clamp and pull it off.
Now we can get the plastic spacer removed. There are three bolts on the bottom side and 2 on the top, remove them and it will pull right off.
There are 2 bolts that come up from underneath that need to be removed to get the intercooler out of the car. One on each side of the intercooler itself.
Once those are removed, simply pull the bottom part out and drop it down and it will come out.
Here are some shots of the stock intercooler next to the mountune unit. The overall size is about the same, the design and efficiency of the mountune unit helps with intake air temps and pressure drop over the factory unit.
We need to transfer the rubber seats off of the factory intercooler to the mountune unit. They just pull off and slide right on.
When installing the mountune intercooler in the car, slide the top in first, ensuring the rubber seat sits properly in the top seat, then slide it in place.
Then you can run the stock bolts in from the bottom and tighten them down.
Next, we can slide the factory intercooler piping and clamps on the mountune intercooler and tighten them down.
Now take a look and make sure everything looks straight and everything clears.
We can reinstall the front clip now and take a look at the intercooler. Looks pretty good in there, don't you think?
We put the mountune logo on the front of our intercooler; this does not come with this kit.
We have yet to install a COBB Tuning Accessport on our Fiesta, but when we do, we will check in with some numbers. For now, it feels about the same as it did in stock form. The computer has a torque limiting table that it follows so simply installing this intercooler won't gain you much more than a more consistent power delivery and better turbo response. We have put about 400 miles on the car with this intercooler and everything seems to work great! We look forward to installing the Accessport and really open this thing up. Thanks for reading and we will update when we get some more stuff done!
