AEM X-Series Wideband O2 Air Fuel Ratio Gauge Kit – LSU 4.9 Oxygen Sensor + 15*4.3cm Decal, Model 30-0300 30-4110

Take control of your engine's performance with the AEM X-Series Wideband O2 Air Fuel Ratio Gauge Kit. Designed for those who demand precision and reliability, this AFR gauge kit includes everything you need to monitor and adjust your air/fuel ratios (AFR) for optimal performance, efficiency, and engine health.

Key Features:

🌟 Advanced Wideband UEGO Sensor & Controller
The Bosch 4.9 LSU sensor accurately monitors your vehicle's AFR during the tuning process, ensuring that you avoid dangerous lean fuel mixtures that can lead to engine damage. With the LSU 4.9 0258017025 oxygen sensor, this gauge delivers precise and real-time readings from 10:1 to 20:1 for gasoline and other fuel types like E85, ethanol, and methanol.

📊 Digital LED Display with Color-Changing Needle
Designed with a 52mm (2-1/16”) gauge housing, the X-Series AFR gauge features a clear digital LED display and a sweeping LED needle that changes colors to show the shift from rich to lean AFR. This visual feedback allows you to monitor the exact condition of your air/fuel ratios, making it easier to adjust for peak performance.

🔧 Easy Installation & Customizable Design
The kit comes with everything you need to set up your wideband AFR monitoring system. The gauge housing fits most gauge pods, and the included Bosch 4.9 LSU sensor and weld-in bung ensure a smooth installation. Plus, with interchangeable black and white faceplates and black and silver bezels, you can easily customize the look of your gauge to match your vehicle’s interior.

⚙️ Wide Compatibility & Versatility
Ideal for use with EFI and carbureted applications, this X-Series Wideband AFR Gauge Kit works with various fuel types, including gasoline, E85, ethanol, and methanol. It provides 0-5V analog output for use with data loggers and engine management systems, making it perfect for professional tuners and car enthusiasts alike.

Why You Need the AEM X-Series AFR Gauge Kit:
