Generally speaking, you should pour the SeaFoam in the oil (1/3 can) and drive if for a few miles (I did for more than 150miles). This should allow enough time for oil sludge (if any) to be dissolved. Even though you add sea foam to intake (1/3 can), any dirt disloged can find its way into the oil. That is the reason to change oil after seafoaming, or waiting until oil change is due to clean with sea foam.

also, can i let my car idle after 15-30mins after use?
and how long do i have to high rev while its cleaning?
also, i have the ngk irridiums(sry if mispelled) and i think it has 1k miles on them.. could i just take them out and replace them with new cheaper ones to use for cleaning then put ngks back in, or is that bad?
First off, what engine do you have x99suplarax? I'm guessing 1MZ V6...
1. You don't need a set of extra hands for SeaFoam application, since you can accelerate the engine at the throttle body cable, but its easier with two. Its only during the application.
2. If you accelerate the car a bit, the engine won't bog down or die from not having vacuum on the line.
3. I don't see any problem with letting the car idle after 15-30 mins of use. Typically, once the car has rid of most of the smoke, you can drive it normally and rev hard to remove any leftovers.
4. If you still have the old plugs in, sure, change them if you want.
