I wouldnt do that unless you have something to regulate and slow the flow of that sea foam into engine down. If you suck it in too fast you could bend valves. The brake booster vacuum hoses would be the best place to put it in. Also after it sucks in shut the engine off and let it soak to eat carbon up. Then later start it up and blow it.
