if you live in a cold area go with the copper iso. if you live in a warm area go with the iso thermal.

^ What if you live somewhere that is warm in the summer and cold in the winter. It doesn't hurt to have Copper Iso in warm weather too???

No it won't hurt, but if he lives in CA or AZ like you and I do, IMO that's just throwing away your $.

iso thermal 5/16" for 220 shipped

What if i live in a cold place but only drive it in the summer??LOL

I thought it alternated from hurricane season to summer. I lived in Orlando for a bit. I miss the humidity. A dry heat is not better, that's bullsh*t.

i would get the copper, its only a little more

I would still go for the copper iso. It's just a few bucks more, and what if you do need to drive in some cold weather...i'm sure you don't want to restrict yourself.
