I need some experienced posters to give me some insight on which is the best type of plug to use. The current plugs in my Civic are NGK PZFR6F Platinums. I've priced the Iridiums at $12.99/ea, which seems steep for a spark plug. There are also several types of platinums available as well.

Might as well pass along a source that I found. Left click below:

go iridium, most of the users here use iridium, including myself, they just seem to burn hotter, platinums just dont seem to do as well in our cars, stick with ngk iridiums, its what everyone will tell u anyways
