How do you use sea foam?

Personally I use it via the gas tank on both the truck and ATV.

The basic way most people use it is through the upper intake manifold. Those are all the videos on youtube you'll see with the white smoke flowing from the tail pipes.

Disconnect the vaccum line (on my last LS2 it was at the rear of the intake mani) and have the engine running. Fill a cup with the Seafoam and slowly let the engine suck the seafoam into the upper manifold and into the combustion chambers. The goal is not to kill the engine but to keep it running. Once all the seafoam is in turn the engine off and let sit for 10-15 mins then start it back up-done.

In addition to the above you can also add Seafoam to the crankcase (oil) and the fuel to clean the fuel system. If you have adapters it can be added directly to the fuel rails for a more direct approach to the injectors.

Just my tid bits I know about doing it
