I wanted to hear from some of you that may know more about BG than some friends of mine. They are recommending that i do a Full System BG treatment to my 02 wrx. From what i have read it goes through the intake and cleans out most of the build up inside. I guess there is also a coolant treatment as well. My main consern was the turbo. If i do this treatment will it have any bad effects to the life of my turbo. Or is this something good to do?
Any comments will help
