The FSWERKS Cool-Flo for the Focus ST/RS eliminates the factory airbox to allow for maximum airflow from all angles, yet still provide a barrier from engine heat. We achieve this by utilizing our powdercoated tig welded aluminum heat shield, which has a rubber hood seal that meets up with the hood when closed. Additionally, to further maximize airflow our heat shield incorporates a 3" inlet right at our high performance air filter compared to the factory 2.75" inlet. The factory airbox was designed, in part, to be quiet to meet the needs of the general population. Once the airbox is replaced with the Cool-Flo air intake system a much more aggressive and sporty engine note will be present. For the majority of auto enthusiasts, the resulting sounds of the turbo spooling and diverter valve whooshing is as greatly appreciated as the added horsepower and torque. We include all of the necessary hardware and instructions for installation. Lifetime Warranty.

Note: A noticeable increase of induction noise is created with all open filter air intake kits.

Cool-flo air intake system

Very easy to install. It definitely opened up for more air I can hear now how the filter is suctioning a lot more air. That car it is more responsive as well.

2014 Focus ST

So far the filter and shield have done everything they should. Factory intake piping is sufficient so I just purchased the shield and green filter and it does the job for the engine bay looks and little extra sound from the factory recirc valve. I highly recommend!

Awesome product guys

This intake fits perfect on my ST ....the power and sound is Awesome :-)


Exactly what I was looking for

Since it's rather debatable it an aftermarket intake actually results in any hp/tq gains I didn't really want the hassle and extra cost of putting in a new pipe, but I really wanted to hear the turbo spool and bpv go pssshh. This does that perfectly. The only reason I'm giving it 4 stars is due to having to loosen/ take off all the hardware keeping the shield on in order to remove the filter for cleaning/reoiling. It's only 3 bolts and a hose clamp but 2 are really annoying to get at under the filter. Anyways I would definitely recommend.
