AEM 30-4406 -30-35 PSI Boost Gauge

Awesome

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.

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!

Works good. Easy to install.
