What plugs should i run with P heads ? The plugs meant for that head ? Or a plug meant for a mustang e7 head ?

I am running the 764s right now, and thats what the explorer w/ p heads calls for.

Any input ?

 

Those should be fine for your car

 

The 764's that is[8D]

I use 104's in mine and they work pretty well also

the way I have always had it explained when I was reaserching it

764's or 104's for N/A or smaller nitrous shots

and

763's or 103's for forced induction or larger shots of nitrous (100+)

 

a autolite 25 plug does not have the proper length for those heads.. use the 764, the 104 is actually a colder plug

 

Aiight, i'm gonna throw some new plugs in before i drive 1300 miles. Thanks
