Swoop,

The Nissan K21 and K25 engines all come with NGK FR2B-D plugs.
There is a tech bulletin put out by Nissan not to use anything but NGK FR2B-D plugs as they have the last few threads removed so that they do not pull the threads out of the head due to build up of carbon.

Denso does not produce a plug with the threads removed and in the heat range that the NGK is.
