AEM’s digital display gauges feature a standard 52mm gauge housing that fits in most gauge pods and can be remotely mounted virtually anywhere. Each gauge includes interchangeable silver and black bezels and black and white faceplates to personalize the look of your gauge—it’s like having four gauge designs in one!

    • Its the best
Aem is the best and gave accurate boost readings. Setup was easy did it in my home garage

    • Quick and easy addition to my EVO X
I bought this to mount in my EVO X to watch my boost levels while driving and I am very pleased with the ease of installation and design of this gauge. I also like that they include two different color choices for the boarder of the gauge (black and silver). Installation was easy especially since there are YouTube videos available to show you how to set this up with. All-in-all, the ease of installation, color options, and accuracy makes this a good purchase and I would buy again if need be. ... show more

    • Love it!

The media could not be loaded. I had high expectations given the price point, I liked the fact it had customizable faces as I wanted white specifically. Only complaint is that the boost sensor wire was rather short when compared to their AFR gauge, I installed probably about 2 feet of wire to get the sensor connector from in my engine bay through my passenger firewall grommet and back to my driver side dash. My 07 Vibe is fairly compact so I was shocked the wire wasn’t longer, but it was easily fixable so I had no issue with it. It gives accurate and virtually instant feedback when vacuum/boost pressure changes at all so I’m very pleased with that. Includes a serial and monitoring wire as well if you’ve have another device that requires the sensor feedback which is super handy. Overall I’m very pleased at the price point, they even included multiple ways to integrate the gauge into the boost setup which was convenient. Lastly, it came with very detailed instructions so that was a plus! ... show more

    • A must have for boosted cars

AEM is a well known company in the car world, and makes high quality products. I purchased this gauge to replace a Prosport boost gauge that fried. Installation was painless and took roughly 20 minutes since I reused the air hose from the Prosport gauge. I strongly recommended that you buy an add-a-circuit fuse kit (ASIN B01LFXA5UA) if you don't have any, it will make installation much easier so that the gauge can be powered by one of your car's powered circuits, like the radio. The kit also comes with several butt splices although one would suffice. The cables for the gauge are extremely long, so be aware that you must have adequate room to tuck them away. I paired this gauge with an AEM UEGO Wideband gauge (ASIN B00N3VGPYS) and SMY Dual Gauge Cluster (ASIN B01M7MEKUS). The numbers are also very readable in the day time and stand out in the night, although the sweeping color band is a bit washed out during the day but still visible. No issues with this gauge and I'm very pleased! ... show more

    • An Ideal upgrade...part 2!
Previously, I reviewed the AEM air/fuel digital gauge, and along with this gauge and a customized gauge pod, my look now has a factory appearance! As previously mentioned also, I've been getting a lot of positive feedback. Case in point: I recently went to my old job where we were having a holiday breakfast (I'm retired). When I showed up with the new gauges and the customized gauge pod, the crowd went wild! My friends wanted to sit in the car and they wanted to know where I purchased the gauges. Of course, I volunteered the information, and also explained the ease in understanding the gauges as well as pointing out how much better they performed as opposed to the previous analog gauges I had. I never had the response with those gauges as I do now! I'm so glad I made the purchase. ... show more

    • Great digital boost gauge
I purchased this gauge for my STi. Install was easy, I made my own little bracket to mount it in the engine bay. The boost sensor I first received was defective, but I sent it in for an RMA and they got a new one to me very fast. The gauge is very readable in the daylight or at night. It is extremely responsive - probably as good as a mechanical gauge. Build quality is solid, and wiring it up was very easy (only 2 wires, +12v and ground). A T junction is provided to tap off the hose to your BOV/BPV. The only con I see to this gauge is there's no indication, other than the LED needle's position, when it's reading vacuum or boost. Sometimes when I glance at it quickly I see a 2 or a 4, and I don't know if it means a slight vacuum or slightly in boost. That being said, it should be quite obvious whether or not you're pushing 15PSI boost or 15vacuum, so it's not a deal breaker, just something that would have been nice. It's also extremely difficult to take a nice picture or video of this gauge in action. Pictures make it out to be very glossy/reflective, and it flickers in videos. ... show more
