Only think I can say compared to the authentic AEM gauge is that this one responds just a little slower but is still accurate. ### ⭐⭐⭐⭐⭐ Review *by G***O on 5 January 2026* Funciona perfectamente ### ⭐⭐⭐⭐⭐ Review *by A***R on 30 July 2025* This kit comes with everything you need and works great with accurate readings. Easy to install, looks good, and even customizable. Both the wires are more than long enough for any mounting location. I have been using this gauge for the whole summer in my Boosted car and it has held up great. Also it's way cheaper than the name brands and I can't see why you wouldn't go with this. ## Frequently Bought Together - Wideband UEGO Air/Fuel Ratio Gauge 52mm (2-1/16”) with 4.9 LSU Sensor, Digital AFR Controller Gauge, Wideband O2 Control Sensor kit | 0-5V Analog Output (10-20 AFR Range) - GlowShift Universal Black Single Gauge Swivel Dashboard Pod - Fits Any Make/Model - Swivels 360 Degrees - ABS Plastic - Mounts (1) 2-1/16" (52mm) Gauge to Vehicle's Dash - GlowShift Tinted 7 Color 30 PSI Turbo Boost/Vacuum Gauge Kit - Includes Mechanical Hose, T-Fitting & Wiring - Multi-Color Display - Black Dial - Smoked Lens - for Car & Truck - 2-1/16" 52mm --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/432122408-fhrhry-wideband-uego-air-fuel-ratio-gauge-52mm-2-1](https://www.desertcart.vu/products/432122408-fhrhry-wideband-uego-air-fuel-ratio-gauge-52mm-2-1) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-11*
