Thread: Autolite 104's during winter?

So, I currently have Autolite 104 plugs in my GTP as I planned to drop pullies but never got around to it. My question is, will they be fine to run as it gets cold? I know they are 2 heat ranges cooler than stock, and I'm figuring the cold will factor into that even more being stock. Should I be worried about anything or just leave them?

What size pulley do you have, and what do you want to drop to? Other mods?

might foul a little easier but should be ok.

Staying stock now, so 3.8.

You might not want the cold of a plug for a stock pulley. Even in the summer.

I wasn't planning on staying stock, planned on dropping to a 3.4 but never got around to it. Was just wondering if any damage can be done and what might happen if I run this cold of a plug in winter. Why wouldn't I want to Ricky?

I ran 104's on a stock pulley for almost 6 months and had no problems. The plugs did however need to replaced upon dropping to a 3.4 pulley. So I would think you would be fine..

You can notice fuel mileage go down.

Replace them with 606's or 605's, 104's are far too cold for the stock pulley.

Noticed this actually. I'm usually around 24-25 MPG, 20 MPG right now. I was shaking my head earlier lol.

The colder weather also does reduce your mpgs, but running that cold of plug is not needed. I would swap them.
