Great Quality, Little Pricey

Installing on a 2006 ZX3 2.0 was straightforward. Took longer to remove the factory intake and snorkel, than it did to install this one. This intake tube and filter paired nicely with my Cosworth intake manifold and throttle body. Although a little pricey, with shipping not included, I don’t regret purchasing this!

Installed in 2010 Ford Transit Connect

I love the product. I installed in a 2.0 Duratec Ford Transit Connect van. Things that were different: 1. Had it use a 76mm to 70mm intake reducer. 2. Relocate and push the transmission cooler return line toward the driver side. 3. Drill and Retap the frame boss for the FSWerks rubber mount. 4. Plug an emissions port with a vacuum cap. 5. Fabricate a breather hose from the valve cover.

Wow! Uncorked

Install was easy as hell, Paired with the race exhaust, header, Brisk spark plugs, and 93 octane tune this realllly opened it up. Above 4000 rpm it almost feels as if you’re giving it a little shot of nos. Don’t get a tone of induction noise from it or at least that I can hear but it really woke up the car. Well worth the 200$ would highly recommend buying it if you want to feel a bit more power.

Works and fits great!

Definitely added a little bit of power especially in cold weather you can feel it. Fit perfectly and adds a bit of sound but my exhaust is so loud I can't hear it from inside the car normally.

High quality, noticeable improvement

Removal of the oem airbox and installation of the intake was very simple. noticeable improvement to mpg, as well as acceleration and sound. had to use a heat gun to get emission cap to fit, and maf sensor had to be removed from harness and rewrapped, but no issue there. well worth it

Installed on a 06 ZX4 ST, replacing the "lifetime" filter assembly. This is my second Focus project.

Get one. You won’t regret it.

Install was simple and straight forward. Much lighter than the original. And I love the growl the intake now makes when I step on it.

Big difference!

Very easy to install, the placement is perfect for making power and protecting the filter, and the overall sound is 100x better! Highly recommend!

Sounds great

I’ve got a 2010 Focus SE with a muffler delete and 1 of 2 resonator delete. This produces a nice deep tone (as far as 4 bangers go) and really knocks the droning noise down on the highway/interstate. Only reason I gave it four stars is because the emissions cap that came with it did not fit. I had to go to a hardware store and get a rubber plug. It’s been installed for a couple weeks and haven’t had any issues. Not a huge deal but slightly annoying. FSWerks, I’d consider including the plug in the kit rather than the cap.

Installation and Performance on a 2011 Ford Focus SE

To put it in I had to first connect my valve cover hose and the emission hose, remove the MAF sensor from the old intake and manage to make the wiring harness string from one part of the engine bays sidewall and drape it loosely until I could easily plug it in. Removing the old air box and intake was pretty easy, however removing the sensors and fitments from them took a lot of prying. The emissions hose in the bottom for the 2008-2011 ford focus needed some greasing to fit well in there and be snug. To actually get the filter in I had to remove the fender well, place the filter inside, and then put the new air intake on the throttle body. Honestly had a lot of fun doing it, and for a beginner project working on their first car without there being any kind of documentation on the internet for how to do it I honestly struggled. All in all I'm happy with the product, had fun installing it and will definitely be buying more products for my vehicle from FSWERKS in the future!

Not as easy as I thought

Ok, so it was a little complicated that I was expecting. I’m so super glad that a few people made YouTube vids, that helped me. Overall, wasn’t bad, sounds amazing and I’m super happy

Perfect placement and great quality

The cold air intake went on perfect without a hitch! The filter placement is in the part of the Engine bay where it’s nothing but cold air love it!
