I'm changing the plugs today in the above vehicle. While I have the plugs out I was wondering if there would be any benefit to spraying any type of TGDI cleaner into the spark plug holes during this process and if so how long would I want it to soak? I have a can of Gumout Regane Direct Injection cleaner or could use plain carb cleaner or Sea Foam. TIA

I like AMSOIL Power foam. Although it won’t touch the intake valves. Unless your having issues I wouldn’t worry about it.
 
I wouldn't put fresh plugs in after a soak - good chance a chunk of deposit will flake off and fould a plug or stick on a valve seat. If you really want to soak, id put the old plugs back for a couple days of blasting then carefull ( cleanly) install the new plugs.
