autolite was the factory plug for ford for quite a while untill they made motocraft
and yep them ac delcos sure are crap
since they are the stock plug in my gmc and have over 100,000 on them and still no misfire
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
