Nope.

God, I love that Bentleys. The 3B engine does *not* spec the W7DTC
plugs; they are the <whatevers> you said above.

The size and heat range look different. Don't try this at home,
but it might be possible that the F7DTC that the 20V NA engine
uses is a better fit. I'm about to pop some into my 90Q20V.
