The stock spec is .028". going to .030 or .032 should be fine and is a
common setting for many vehicles of that era. The water boxer does tend to
erode the center electrode over time. A reasonable replacement interval is
15,000 miles. Platinum's can go longer as the center electrodes don't wear.
While not listed for the application I like the Bosch Quad plugs, #4477.
These help to smooth out the idle and lower HC emissions as they miss fire
less.
