I'm planning on changing the plugs in my 07 and have followed the various threads here about which tools to use and all. In the TSB 08-7-6, which I think is still the most current, it says to remove at room temp. Well, I don't have a heated garage to work in. What do you guys think about doing this job in 30 to 40 degree weather?

 

room temp is ~80 degrees according to them.

 

It's going to be months before my truck see's that type of temperature again.

 

Just start it up for a min or 2 then change them. And put a one piece plug back in
