## Description

AEM 30-0302 X-Series Temperature Gauge, Black

Review: Excellent purchase - I’m very happy with the purchase, it arrived quickly and everything was in perfect condition and complete
Review: Don't go cheap on Chinese no name gauges.... - Just got this gauge for my car, got it installed and I gotta say its pretty nice. Its comes with everything you need and the wiring harness is long enough to reach pretty much any point in the engine compartment. Easy to hookup and the manual that comes with it is pretty easy to follow. I went ahead and plugged in my OBD2 scanner and pulled up the live data for the ECT sensor and compared that reading with the one on my AEM temp gauge and they matched up perfectly. I can give one piece of solid advice to anyone wanting a temp gauge for their vehicle, dont cheap out on chinese no name gauges....they will fail within a year or two. Bite the bullet and spend the money on one of these gauges, you wont regret it. This gauge also has a warning and peak function. It'll basically warn you by blinking rapidly once its reached the temp youve programmed it too. Overall very nice gauge.

### ⭐⭐⭐⭐⭐ Great guage
*by B***R on July 20, 2018*

Works great, love these x series guages!! Only downside is that it doesnt come with the faceplate i needed. I had to buy the extra faceplate for oil temp, at this price youd think they at least have the oil temp, but i cant give it 4 stars just for that.
