i just put autolites in my duratec and oh my god i wish i did it a long time ago. i had the Bosch+4 plugs and they SUCKED ASS!!! I WILL NEVER USE BOSCH AGAIN. those things must have retarded my timing because all sorts of things were wacky. i even had a slight tick in my engine. Once i changed the plugs, the tick went away, car is more responsive, fuel burns better so now my exhaust doesnt smell like [censored]. i recommend the autolites
