Prosport Bosch Wideband LSU 4.9 5-Wire O2 Sensor (Universal; Some Adaptation May Be Required)

Wideband Oxygen Sensor. The Prosport Bosch Wideband LSU 4.9 5-Wire O2 Sensor is a precision sensor that measures exact air/fuel ratios across a broad range from rich to lean mixtures (10:1 to 20:1). It is designed for performance and tuning applications, providing accurate air/fuel data essential for optimizing engine performance, emissions, and fuel economy.

Construction and Appearance. This sensor features a planar design with a two-part sensing element for rapid and precise oxygen measurement. It includes an internal heater element that reaches operating temperatures around 700 to 800 °C within 20 seconds, enhancing sensor responsiveness and durability.

Installation. Installing this sensor requires basic mechanical skills and fits standard oxygen sensor ports without the need for drilling. Some adaptation may be needed depending on the specific exhaust system configuration.

Application. The sensor is designed as a universal fit and is compatible with a wide range of aftermarket wideband air/fuel ratio monitoring systems, making it suitable for various tuning and engine management setups where precise AFR readings are critical.
