For everyone's info..
I E-mailed NGK and got this response today.
Just for peoples future reference between NGK and Bosch.
According to my notes, Bosch WR7DC crosses to a BPR6ES NGK spark plug.
The BP8ES plug you purchased is two stages cooler. These plugs should
be a good starting point on a turbocharged vehicle. Thank you.
