I use to turn wrench's for a dealership and we exclusivly used BG products. And take this from a cetrified technician they actually do work. But they only work so much so its not always a fix all, if it clogged to all hell then the only real way to fix it is to take it out and either clean it or IMO if your taking the case out just replace the evap.
