bottom line almost no spark plug on the market is "crap"
you trying to tell me that ngk uses some alien form of technology that makes the fuel in nissans (which aparently must go throught the nissanification in the injectors making it different from all forms of fuel) burn correctly and no other plug company can get the spark right
Yes , alien lifeform spark plugs from mars to be exact.,
NGK is my preference. I ran some AC delco once cause they were out of NGK ones and one of the plugs was cracked when i switched them out at 10k .
If Ford or general motors is your thing sell your se-r and go buy a focus or a cavalier so you can run the autolites
ON topic :spark plugs have come along way, platinum, V tipped irridium etc.
all in all it depends on your aplication colder plug VS hotter plug etc.
