What engine are you referring to?
For a stock carbureted bug engine the standard Bosch plug is a W8AC (equivalent to the old W145 specified in the manual). For severe service you might want to go one heat range colder to a W7AC (W175).
I do not recommend Bosch Platinum plugs with a stock ignition system.
This assumes original-style Type I heads with 14mm, ½" reach plug threads - there are heads out there with 3/4"-reach, even some that take 12mm plugs. If you're talking about a Type IV, that's a whole 'nuther answer.

For a stock to middling T4, the Bosch triple electrode W7DTCs work VERY well, and last a lot longer than a Super, at least.
They may require less timing than what you have been running, suggest Jakes recommendation od 28BTDC total mechanical, or even LESS.
(You will want more initial. I currently run 15 BTDC, 26 total + vac can)
These woudl PROBABLY also work well if you have a T1 w/14mm,3/4" reach plugs (many aftermarket heads) but as I haven't had a T1 in ~20 years, I'm only guessing.
The NGK equivalent to the W7DTC (BP6ET/281...sumthing) is EVERY BIT AS GOOD as the Bosch plug, and is available everywhere for ~1/2 the price of the Bosch plug.

Addendum to Newtons first law:
zero vehicles on jackstands, square gets a fresh 090 and 1911, cabby gets a blower.
EZ3.6 Vanagon after that.(mounted, needs everything finished) then Creamsicle.
