This is a fairly useless modification on this car in my mind. It was already installed when I purchased the car. The issue that i have found is the location is right behind the battery and during install the stock snorkel was also removed from the radiator support. The end result is that the air filter may have more surface area, but it's drawing nothing but hot air anymore. I am currently working on creative ways to fix this issue. Stock airbox is not an easy thing to find for a SVT Focus.
