Here's an old post with good info about NGK's.

Another with response from Jeff Korn:

When I recently had my car apart for a heater core change, I switched out the stock AWSF32C plugs, with only 4K miles on them, to the NGKs (thanks for the tip, Nate!!), and the car runs great. I dont think it ever idled so smooth. No missing ever at any RPM or load. Gapped them at .032.
