My glowshift meter went out after a month and bought this to replace it. The glowshift lighting didn't match my 08 Volvo C30's OEM gauge lights but this gauge does it perfectly. About to hit 4 months, still reading accurately and haven't had any issues with the backlighting.

Great quality easy to install, package is kinda cheap but it includes all necessary things to install. Back-light is kinda crappy would definitely get an LED bulb.The gauge itself is awesome, Easy to read and looks great. Would recommend.

Awesome product and works perfectly. Very well made and made in the USA which is a big plus. Originally bought a gloshift gauge and what a piece of chinese made garbage that was. Go with autometer, you won’t be disappointed!!

Used this gauge to replace a faulty digital boost gauge, for that it worked perfect. My only complaint is that the gauge face was not centered in the housing. Each time the boost line was tightened on the back of the housing, the face moved slightly. Irritating, but livable.

This is a nice little gauge. Very responsive and accurate in my experience and comes with all the hardware you need for a quality install. The red illumination cap it comes with makes the gauge a great color match for the orange lighting you might encounter in a BMW or a 90s Audi (urS4/urS6 specifically, unsure about other models).

The gauge works accurately once you get it installed. Do not buy this for a pillar mount location with a standard pod depth (It won't fit). I had to buy a 1/8" npt female 45 degree fitting to 1/8" male to get this to fit in pillar location. This is only because Autometer use a 1/8" npt to 1/8 compression fitting to hook to the nylon hose. The nylon tubing/hose that it comes with should come with directions on how to straighten and use it. Out of the box this stuff it a nightmare to use. I finally found a video on how to straighten using a heat gun. This is not optional and must be done in order to use the nylon hose. If you don't do this the chance of kinking are almost 100%. Once you kink you have to buy a new tubing kit or buy a connector fitting. Once installed right the nylon tubing will read your boost more accurately and quickly then silicone tubing (the compression fittings are better long term, but made the installed more complicated).The worst thing about the gauge is the cheap light socket that this comes with. It doesn't even fit the back of the autometer gauge. It will fit in the slot and is designed to be rotated to lock in place. What they did is buy the cheapest socket and drilled these two dots for the flange dots to rest in. This does not work at all. The light socket will fall right out. The bulb socket is also loose and the bulb will fall into the gauge. This part is unacceptable. I would return the product if I hadn't already installed it. I replaced the bulb with an led blue bulb to match the rest of my gauge. I had to use a piece of 3M mounting tape inside the flange to both secure the bulb and secure the light socket to gauge. I then used one more piece on top for good measure. I do like how my replacement LED blue bulb looks like with the gauge and is the right light level for day and night with no dimmer. I also like that when this bulb fails I can replace it. My last boost gauge the internal LEDs failed and they are too small for me to fix. Overall all, Autometer needs to replace the light socket so it locks down and provide proper install directions for the tubing. If they did this I would recommend the gauge.

Mechanical so super easy install, just route a vacuum line to it and if you need to, the only wiring is for a backlight
