I have a 95 GT with lots of bolt ons. The motor is totally stock, bottom and top end. I have a Zex dry kit that I haven't installed yet.

I would like to run plugs one heat range colder than stock. From my understanding, copper core plugs are the way to go with 5.0s, so I am leaning towards a set of Autolites.

I just wanted to verify that Autolite 24s are one heat range colder than stock for my 95 5.0 before buying a set. Is this correct?

Anyone else have any different plug recommendation?

Thanks in advance.

yes 24's are one heat range colder than stock. Autolites get colder as the number goes down. 25 if hotter than 24.
