Monitoring the temperature of the air going into your engine is critical to safely extracting the most power from your engine, especially when dealing with forced induction. Cool, dense air will always make more power and contribute to less detonation. AutoMeter’s dual channel air temp gauge allows you to monitor the air temp before and after the intercooler, as well as allowing you to monitor the difference in temps. This lets you see if your intercooler is up to the task and ensuring you're not causing unnecessary harm. Configurable warning set points and peak recall provide crucial feedback that allows you to keep your eyes on the road. AutoMeter’s patented Pro-Control output enables you to set up the ground-controlled output to control intercooler sprayers or other devices.
Feature Points
  • Monitors both upstream and downstream intake air temperature to accurately measure intake tract/intercooler efficiency
  • Displays both pre and post intercooler as well as temperature difference
  • Configurable Pro-Control output allows gauge to control exterior auxiliary devices based on downstream temperature (intercooler sprayer, water/meth, etc
  • User programmable warning functi
  • Peak recall/memory
  • Display in Fahrenheit or Celsius
  • Includes two 3/8” NPT threaded air temp sensors, 12ft long wire harness, mounting hardware, and detailed installation instructions
  • 12 and 16 volt compatible, works with nearly every street car or race car electrical system

HI, was wondering if both upstream and downstream temps are displayed simultaneously or do you have to switch back and forth? Any links, video or images of this gauge in action would be great. Thank you.

Asked by: Joe Thomas
Hi Joe, You can set this gauge up so one sensor displays on the peripheral bar graph, and the other sensor displays on the center digital display. Thanks, Jim

Can this be dimmed? I live in a very dark environment and these become a flashlight in my face if not.

Asked by: Dread53
Thank you for the question. Yes, the 6158 can be dimmed. Once 12V is supplied to the white wire, it will enter a dimmable mode via that white illumination wire.

I am just wondering if you make a cobalt series, dual channel air temp gauge in C°?? Cheers

Asked by: Andrew Byskov
Hi Andrew, thank you so much for the question. This Dual Air Temp gauge actually has a setting to easily switch from a Fahrenheit to Celsius reading.
