    Accurate and easy to read

    I have used both 30 & 60 psi range gauges and I will never be using any other brands boost gauges. Easy to read, even in off road applications. Comes with all needed hardware for installation.

    AEM 30-0300

    One of AEM's newest most recent wideband for 2018... This gauge is also on social media as 1 of top ten to choose, and I believe 2nd or 3rd in the order... I chose this for the quality of this being the first single board design and jst hobby style harnesses to plug and play to the guage... The setup is also great bc it is also a lambda and uego read on the LSU aswell... This means e85 compatible... The no obstacles that were of AEM guages of yesterday are in the past bc this opens doors for more of these guages to be standard so the harness is plug and play the guage is single board, has digital dim and blackout feature.. So many things that make this a can't go wrong choice, other than being pricey in the market; which was only thing was and I waited for a great price.. This is AEM's newest and these dont need a freeair calibaration when newly installed and also the LSU can be used in the bk right of offroad setups or can be traditionally welded with the sleeve bung... Too many things not enough to say about how great this is... Perfect is all I can really say...

    Peace of mind at a Glance!

    This is one of the best gauges for monitoring A/F because of the big red easy to read from a glance numbers as well as the parameter light that will definitely let you keep your eye on the road / track ahead and still catch a glimpse of the green light without actually looking directly at it. It's just in your line of site so you know your A/F is fine

    Yeah boi

    I read and followed the directions for the oxygen sensor install angle and fixed any exhaust leaks. it works great and can finally fine tune my carburetor.. I found out why one of my many carbs always got horrible mileage even with very lean jetting, the idle air bleeds were about .012" too small

    Instant reading results.

    If you spent money on an engine build and want to keep an eye on your afr's this is what you need. This gauge and sensor assembly are so quick to read data and update so you know exactly where you need more or less fuel to keep your engine safe and running at its peak performance levels. Hook up is so simple, just need a power and ground and plug in two connections. Cheap insurance when you start thinking of how much you spend on an engine build, or can spend rebuilding if you didn't have this gauge

    A+ Best wideband on the market at this price point.

    Works great. Comes with nice high quality covered wiring harnesses with nice weatherproof connectors. If you want to know exactly what your engines afr is spend the money on a good wideband like this one.

    Best Wideband

    I always used Inovate gauges for tuning but after all the research I did the AEM X series had very good reviews for giving quick time readings so I got this and wasn’t disappointed at all. It also reads lambda on the spot which is good for tuning with other fuels.

    AEM makes some great stuff

    I've installed a couple of AutoMeter AFR gauges, and while they're good, I think this AEM is better. The wiring is higher quality, the gauge itself is almost 1/3 the depth, and man it's reaction time is fast. Just a good product. AEM makes some good gauges.
