Product Description

The Innovate Motorsports 3737 is a universal Bosch LSU 4.2 wideband oxygen (O2) sensor designed to deliver accurate air-fuel ratio measurements during tuning, calibration, and performance monitoring. Featuring a 5-wire configuration that compensates for temperature and signal variability, this sensor provides dependable data essential for high-precision engine tuning. It is commonly used as a direct replacement for original sensors in Innovate wideband systems such as the LM-1 and LC-1, and can be integrated with a wide range of gauge or controller products when proper wiring and interfaces are used.

Ideal for performance enthusiasts, engine builders, and tuners, the 3737 sensor enhances the capabilities of AFR (air-fuel ratio) monitoring systems by offering reliable readings across a wide range of operating conditions - including naturally aspirated and forced induction engines - when installed in an exhaust sensor bung or adapter. Because it is a universal part, fitment depends on matching the sensor to the correct controller and adapter setup rather than a specific vehicle application.
