Prosport Premium Series gauges are the top of the line in terms of features and included parts. A push-button on each gauge activates the peak-hold feature, which lets you know the highest point that the gauge has reached. It's great for racing or other conditions where you can't be staring at your gauges the whole time. These gauges also have a user-programmable warning function, so you can (for example) program your boost gauge to blink and beep if boost exceeds 21 psi. (The beep function can be disabled.)

The gauges are available in amber/white backlighting, and can be wired to display in one or the other color, or switch based on whether the car's lamps are on or off.  (Note that Prosport's "amber" color looks a lot like "red" to us.)

Like more expensive gauges, Prosport Premium Series gauges can be daisy-chained together. Just wire up ONE gauge for power/ground/lighting, then run a short jumper harness to each additional gauge! Jumper harnesses are included with each gauge, of course.

Oh, and best of all, this gauge has both "opening ceremony" behavior (just like those mega-buck gauges everyone wants), as well as a shut-down display!

60mm gauge size. Reads 30 in-Hg to 30 psi.  Includes sender, complete wiring harnesses, gauge mounting stand, gauge cup, hood, and installation instructions.
