im getting gauges soon should i go with eletrical or mechanical??

 

mechanical are cheaper, ele. are probabley not as hard to put in. most on here have mech.

 

but which work the best or does it matter??

 

My mechincal gauges have worked flawless for over 40K miles / 2 years now. I would suggest DiPricol gauges being they are the most inexpensive set you can buy. But they are of good quality and design!

I got my setup at...
