What spark plugs

May depend somewhat on what you have had done to your engine but alot of guys (myself included) use Autolite 24's for the street. I use the 23's (one range cooler) for the track. HTH
That will work just fine, or use AC R43TS. If you're equipped with a larger turbo, higher boost levels, etc, go with AC R42TS.

...or, the Autolites, whichever's the least expensive.
What plug gap are you guys running with larger turbos.
Still at .35 I heard some people have had a misfire from higher boost, so they closed the gap to .33 True or false
