- HFP-WBS49 is a professional-grade wideband Lambda (O2) sensor designed for high-speed, high-accuracy monitoring of air-fuel ratios in performance-tuned engines
- Precision Controller Compatibility: Specifically engineered as a direct replacement for the AEM 30-2004 sensor; compatible with the AEM 30-4110 Digital Wideband, AEM 30-0300 X-Series, and various Autometer, FAST, and Dynojet controllers
- LSU 4.9 Architecture: Utilizes the superior Bosch LSU 4.9 design, offering faster light-off times and higher accuracy than older 4.2 sensors, all without the need for periodic "free-air" calibration
- Extensive Cross-Reference: Replaces multiple performance and OEM part numbers, including Autometer 2243, FAST 170408, AC Delco 213-1572, and GM 12575657
- Important Fitment Note: This sensor features the ROUNDED electrical plug. Please verify your harness before purchasing, as this unit will NOT work with controllers requiring a square-style connector
