With some good technical knowledge about the spark plugs, it *should* be possible to spec out an NGK plug for the 16V heads.

You need to know the hex size (known to be 16mm), the thread size and reach, resistor plug (pretty standard for all cars now days), projector or non projector tip and possibly the reach, heat range, and any special tip design (probably not an issue here).

I'd venture to say that with a little bit of time and searching an NGK plug could be sourced easily.
