NGK BP6ET work too - they are tri-electrode too.

The Bosch tri-electrode plugs do come pre-gapped - there are
different gaps available.   Bet you don't get any choice
at the generic parts stores.

I have also run Autolite Platinums (quiet out there).
No noticeable difference from the tri-electrodes
with boost set at 1.8bar.
