2013 Focus ST I had watched numerous videos of lots of different applications from basic filters to full CAIS, so I knew what I was getting.The filter itself is top notch and the box lid does make noticeable improvement over stock, although patience is required when fitting as it is quite rigid. With this kit, I found personally that throttle response is improved and the performance sound is great, you actually get to hear the recirc valve now. I can't say that there is any difference in outright performance as I can't notice but over long runs the engine temp is cooler and takes less time to cool. I would recommend this kit 100% to anyone thinking of replacing stock.
