2001 F-150 4.6 am doing 50,000 mile maint. had some transmission fluid issues so i figure while i'm at it.......question
is does anyone have a pref. between NGK or Bosch,or are they
about the same. i have heard the "exploding"/Vibrating loose
plug issues and so i thought i would ask the forum. also
have been looking into warranty specs,and i am not sure
if i am going to have an issue with either of these or not yet.
just seeing what works for you guys.....Thanks.....Dave

 

NGK or Bosch?
None of the above.....Motorcraft is what I would use

 

I agree, Motorcraft double platinum!!! Autolite is basically the
same plug, both are made by Honeywell.....

 

Thanks guys,well give it a try.....Dave

 

as stated above, my vote goes to motorcraft/autolite . And dont forget the plug wires. Expensive but i used genuine motorcraft for my replacement wires.
