<VV> spark plugs

[Bill Elliott]

Bosch Platinums have been extremely troubleprone in Corvairs for 
decades. While some people run them without (apparent) issues, in my 
experience (including a few years with a Corvair-only repair shop), no 
one has actually experienced superior performance with a Bosch Platinum 
over a Bosch Super while a great many people (including yours truly) 
have experienced significant drivability problems with them. I don't 
like them in general and in my experience very few cars actually run 
really well with them.

It's hard to find a better plug than a Bosch Super for the money and 
hard to find a better plug period than a standard NGK.

IMO the NGK wasn't worth the price premium over the Super, but the new 
Super Plus (replacing the Super) is more expensive and I think the NGK 
may now be worth the extra cost...  Additionally, Bosch has discontinued 
virtually all nonresistor plugs in the Super Plus series and I've 
experienced some premature failures and out of box failures...

The max gap depends on your ignition system, the plug, and the 
requirements of the engine (e.g. even with a hot ignition I don't run 
more than stock gap in a turbo...)
