Engineered for accurate air-fuel ratio monitoring, our oxygen sensors feature planar zirconia elements with response times of <100ms and protective stainless steel mesh covers. Wide-band (UEGO) sensors support lambda 0.7-1.3 measurement ranges for precise fuel tuning, while narrow-band sensors provide binary feedback for efficient closed-loop control. Platinum catalyst layers (99.95% purity) ensure long service life (exceeding 100,000 miles), and heated models (4-wire) reduce warm-up time to <30 seconds for immediate feedback. Compatible with popular OE designs such as Toyota O251, Bosch LSU 4.9, and Denso 234-9060, these sensors meet strict EPA and CARB emissions standards. Each unit includes a protective sleeve (10mm hex) for easy installation, with thorough resistance checks (heater coil 5-15Ω) and voltage output testing (0-1V) conducted before shipment. The oxygen sensors play a crucial role in optimizing fuel efficiency and reducing harmful emissions.
