Good To Know
Q: Is this sensor compatible with my PLX wideband controller? A: Yes, this Bosch LSU 4.9 sensor works with PLX Devices SM-AFR and DM-6 wideband kits that use the LSU 4.9, providing a direct plug-in replacement.
Q: Does the sensor require free-air calibration? A: No, the LSU 4.9 uses an internal reference cell that maintains accuracy without free-air calibration, simplifying installation and ongoing use.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
