It is, I went to AEM’s website and compared the part numbers and pics and it is exactly the same. I installed it per instructions and warnings and it is working perfectly. It’s a good deal and a great product. ## Frequently Bought Together - AEM 30-0300 X-Series Wideband UEGO AFR Sensor Controller Gauge - HP Tuners PROLINK+ Cable with Analog and CAN Bus inputs for External Sensors Using MPVI2+ and MPVI3 OBD2 Scan Tools, Cable Only - 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 --- ## 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.pl/products/545054883-aem-30-0300-x-series-wideband-uego-afr-sensor-controller](https://www.desertcart.pl/products/545054883-aem-30-0300-x-series-wideband-uego-afr-sensor-controller) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-06-03*
