I've always stood behind NGK, but I run the "V Groove" plug. Its the same number as the one that runs in it stock just has a "V" or "Y" at the end of the model number.

The manual will tell you the plug gap to run. Really no need to do anything other then the factory settings. Durning the winter if you live in a very cold enviroment you could go one plug hotter and your local auto store could give you the proper model number for that.
