Sunpro Gauges. Many of you love to do little things to your vehicles to jazz them up a little. Here is something that not only looks cool, but serves a great purpose. That is adding a few gauges from Sun Pro. Sunpro has been making gauges since I was a kid, and if you ask me, they are still at the top of the food chain. I recently added a transmission temperature gauge and a boost gauge to my sons Ford diesel and of course, I used ones from Sum Pro. They were priced right (my water/oil temp gauge was $18) and also work the best. Installation was simple because the instructions were so good. Anyone wanting to add a little to their vehicle needs to look at the offerings from SunPro first. They are sold all over, and you can also go to SunPro.com. to look at their online catalog.
