NOTE:  My opinion follows.
Single Bosch Plats are GARBAGE.  They are cheap plugs, utilizing a marketing
image to get folks to buy them (and overpay for what you get).  I'm guessing
any plug would be an upgrade...

Turbo guys, be careful here.  The single Bosch plats don't work well in our
cars.  I'm skeptical that the 4+'s will as well.  The triples seem to work
well.  So do the more expensive silvers.  I'm awaiting 4+ BTDT's on a turbo
car.  I think Mike at Ingolstadt West may have installed a set into a turbo
car.  I'll ask him, and report back with any news.
