What are the best spark plugs I can put in my truck ? I have a 2012 STX 5.04x4.

 

Motorcraft. Stay away from Autolite.

 

Are there better types such as platinum or iridium (I think that's what it's called )

Motorcraft and autolite are one in the same, aren't they??

I have a mechanic friend who's put in who knows how many spark plugs, and while installing some motorcrafts once, out from the carton came an autolite plug. Weird.

 

I think Autolite is bit cheaper plug. Motorcraft for me.

 

What about Bosch spark plugs ? Anyone have opinion on them ?are they good?

 

No.

Stick to Motorcraft.
