The shop manual say 11lbft, plug manufacturers mostly say 13-15lbft. I always shoot for 150lbin (12.5lbft) using a 200lbin capacity 1/4" drive torque wrench. This places the setting in the upper end of the wrench's range where it will be more accurate.
If all you have is a 1/2" drive torque wrench then either get a 1/4" tool, or make them hand-tight + 1/16th turn. There is no way that a 1/2" drive wrench will be sufficiently accurate at 11-15lbft

^^ I would just use a torque wrench...spark plug blowouts are definitely not something you want to deal with...even though yes lots of people have torqued down their spark plugs by hand with no issues...not a risk i'm willing to take.

With sufficient wrench turning experience it is quite possible to torque them properly without a tool--I have done this on many engines over the years.
However, on an engine with a known issue I think it unwise. Since you will likely be using a socket wrench handle anyway, why not use a torque wrench?

but you guys are right it makes sense to use the right tool for the job.
