The FSWERKS Cool-Flo OEM air intake is the system of choice for those who are looking for gains without attracting too much attention, visually. The air filter mounts inside of the factory airbox*, as you can see in the images above, giving you a stealthy appearance. We replace the intake tract plumbing that leads to the turbo inlet with our mandrel bent 3" aluminum tubing and include our high performance Green air filter. We also include a 4 ply hi-temperature silicone coupler, stainless steel hose clamps, rubber mounts, and instructions. Features laser cut brackets and tig welded construction. Upon installation you will hear more of the turbo spooling and diverter valve sounds to go along with your newly discovered power and torque.

The FSWERKS Cool-Flo OEM kit is available in a wrinkle black powdercoated finish. Limited Lifetime Warranty on entire kit.

*Factory airbox not included

Note: A noticeable increase of induction noise is created with all open filter air intake kits. Only the ITG filter part#15BH-262 in the stock air box will maintain OEM like sound levels. 

This product is not CARB Exempt and is not legal for use on public roads in California or other states adopting California emission standards.

FS Werks Cold Air Intake Green Filter

Shipment was super fast, installation was start forward, and the intake looks amazing and sounds even better! Really opened everything up to more air going into the engine. Super happy with it and can tell a difference already! FS Werks is top notch and glad to be running their products on my Focus ST

Install was a breeze with the supplied instructions. The intake sound alone makes it worth the purchase!

Great Product, Better Company

Fits great. A little bit of work to get installed but not terrible. Took me about 90 minutes but I also changed the spark plugs at the same time. Car sounds better and feels like it has more torque, even without an updated tune. I can't say enough about FSWerks as a company. I originally ordered the pre filter for the green filter bc I live on a gravel road. FSWerks called me a couple days later before shipping to inform me that the pre filter would not work with the CAI I had purchased and asked if I knew that or had ordered it without knowing. I explained that I didn't know and they refunded my credit card for the amount of the cover. Great customer service and excellent attention to detail. I will definitely do business with again.
