AEM Digital Boost Gauge - 30-4408
Need to know what boost you're actually running? The AEM digital boost gauge shows boost pressure from -30 to 50 PSI with a sweeping LED needle and a digital readout that updates in 1 PSI increments. You can glance at it mid-pull and instantly see if you're hitting target boost or creeping past it. The gauge also outputs a 0-5 volt analog signal that you can feed into a datalogger or standalone ECU, so you're not just watching boost on a gauge, you're logging it and you can review it later to catch boost spikes, leaks, or wastegate control issues.
Sweeping LED Needle with Digital Readout
The AEM gauge's got a sweeping LED needle that moves across the display as boost pressure changes, plus a digital readout that shows the exact PSI. The LED needle gives you quick visual feedback, and the digital readout gives you the precise number. You're not squinting at a needle on a mechanical gauge trying to figure out if you're at 18 or 19 PSI. You just look at the number.
Auto-Dimming Display
The gauge has a built-in photocell that auto-dims the display based on ambient light. That means you're not getting blinded by a bright gauge at night or squinting at a dim gauge in direct sunlight. It adjusts automatically, so you can actually read it no matter what time of day you're driving.
0-5 Volt Analog Output for Datalogging
The gauge outputs a 0-5 volt analog signal that you can wire into a datalogger or standalone ECU. That's huge if you're tuning the car or troubleshooting boost control issues. You can log actual boost pressure and overlay it with throttle position, RPM, and whatever else you're monitoring. If you've got boost spikes or the boost controller's not hitting target, the logs show you exactly what's happening instead of you guessing.
Interchangeable Bezels and Faceplates
AEM includes interchangeable bezels and faceplates in the box. You get a black bezel, a silver bezel, a black faceplate, and a white faceplate. Pick whichever combination matches your interior. You're not stuck with one look.
