Features & Product Details

This is AEM’s digital boost gauge. This 52mm gauge delivers unsurpassed accuracy, and visibility that you can rely on. Each gauge includes a 24 color coded (Red, Green, and Yellow) LED lights that will change from green to yellow to red for immediatereference to the boost levels, and an integrated three-digit display will reveal real-time boost.

The 52mm gauge will fit in most gauge pods for convenient installation, and can be remotely mounted virtually anywhere. Included are interchangeable silver and black bezels, and black and white faceplates to personalize the look of your gauge. 

The AEM Digital Boost Gauge uses an absolute manifold pressure sensor, which means at higher elevations, it will not exactly zero out as there is less atmosphere at elevation.

AEM Electronics Boost Gauge Digital 52mm ( Part Number: 30-4406)

Worked well for about 3 years. Then the digital readout quit all together. Then the green led started to dim. I would not recommend this for a reliable gauge.

Very high quality, I haven't gotten to install it yet because I don't wanna install it wrong and have a major boost leak. So I'm waiting till I know exactly what I'm getting into. Install you definitely have to know what your doing so you don't cut the wrong line. But since its similar to the AEM AFR UEGO Gauge I'm sure it's just as nice. I have both.

Don't Buy At Altitude 3 years ago

Really nice gauge, i like the "sweep" it does on start up and the digital output HOWEVER do NOT buy this gauge if you live at altitude because it will be off. There is no way to re-calibrate it either. I have contacted AEM and they state that their new series digital boost gauges will have a calibrating feature.

  • Q: Not showing the right boost.   Xavier7 months ago

    Does anyone else have the same problem of it not showing the right boost? My Cobb AP is showing 16psi where as my gauge won’t go past 9psi. I’ve had my gauge for 2 years and recently tuned my Subie and noticed this.

      A:  If you are experiencing different boost readings from your Cobb AP vs your AEM Boost Gauge, we would recommend checking all of your vacuum lines for the gauge to determine if there is a boost leak. As the Cobb AP gets the reading off the ECU, where as the gauge would read through what the AEM Boost Sensor is reading.

  • Q: LED Color Clarification  nsartori2083254701 year ago

    I have seen mixed answers for this. Are the sweeping LEDs for the gauge needle multi-color changing (red, yellow, green) or are they all green? Thanks for your input.
  • Q: plug and play  julius2 years ago

  • Q: Pod  09WRXlover7 years ago

    I see that it doesn't come with a pod . Would any 52mm pod work ? Because I am looking at the STRi 60mm Gauge Pod Visor with Visor but I don't want to spend the extra $30 for the for the spacers to make it 52mm. Would you be able to get the STRI pod in 52mm ?
    • 0 of 0 people found the following answer helpful

      A:  Hello, this will work in virtually any 52mm pod, and unfortunately we do not carry the 52mm STRi pod at this time. Thanks.
