AEM 30-4406 Boost Display Gauge - 2-1/16" Diameter - 30-35PSI

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!

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!

Awesome

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.

Installed it on a 2018 fiat 124 spider. The t-boss is useless had to go buy a different one from home depot but everything else worked fine. Easy to install

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

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.

Let me start this review by stating that this is indeed a fine boost gauge, very precise, aesthetically pleasing, and comes with a black or white background for you to choose. Installation was easy, although the silicon pipe may come on short on some applications. It has some I/O port for logging, which I haven't used yet, so I will not delve on that. The bad: It is so sensitive that i becames somewhat annoying to see the vacuum change from 20 to 19 to 20 to 19 again and again all the time, when the car is in neutral. It would have been awesome if it had some function to mark max boost. The little green light that does the trick of a gauge needle, needs more illumination. Looks quite bright in the picture here, but in reality you will not see it on bright sunlight, specially if you are going 160 mph on the road. Ah, and no led lightning so if it is too dark, you will see the faint green light but no numbers!! (epic design failure!) For 140 bucks I think you deserve at least better design.

Great product, easy enough install. Sometimes the gauge sticks at 0 but other than that decent. Definitely could use a neg sign for vacuum or even a simple positive sign for boost.

works great and it a great little extra for any turbo/SC car. I've got mine fitted inside my MX5's vent and its a perfect snug fit. the only crit (and it's a tiny one) is that the included hose is quite small luckily its still more then I needed but I could see others needing more.

its the second time I buy this gauge , it work awesome . work better of conpetitor look fine into my car better price to amazone whit free shipping !

Great quality boost gauge, easy to install

Works good. Easy to install.
