'08 211 3.5 CGI - Which spark plugs?

[E55BOF]

The last owner of my latest car had a 'B' service done in October, but saved a few pennies by omitting the spark plug and brake fluid changes. The only spark plugs I can find for the car are Bosch; does anyone's experience recommend using anything else?

It's a 272.985 engine, though, not a 272.964. That may make a difference. The NGK alternative appears to be SILZKR7A-S, which looks to be not all that different.
