I wanted to use the RaceAir but be able to adjust CFM. I purchased my own voltage regulator as the Boost was just out of reach for me. Works flawlessly, albeit not nearly as convenient as the Boost would have been. It blows well and I picked up a spare PCI filter. If you are looking for a black outlet, give PCI a call. They are not on the site but they do have them available depending on your setup.
