seafoam

using seafoam in my fuel tank to make it run better? suggestions? is the seafoam like a gel...? pour it in the fuel and swish it around..?

Will It ruin my catalytic converter? Or do nothing? Where should I put it and how much. I only have 1qt. Will it help my car? Wat will it do to my specific car?

I want to seafoam my 2000 Bmw 528i, but I cannot find the proper intake vacuum hose Any help would be great. Pictures would be even better. I don't want to add the stuff to my oil or gas tank. I need it done by intake(Brake Booster) from what ive heard. Thanks...
