digital, analog, or both?
I'd say go for it. Don't know, what do you have for stock guages and how accurate are they? I know in both of my Fords it's the typical C(old), H(ot), or "Normal". (same bs with voltage and oil pressure). Would like to get rid of them simple because they're inaccurate and don't give actual numeric readings...just "Normal" or not.
