Fast O2 Sensor, Lsu 4.9 Wideband - 170413

This Wideband oxygen sensor is capable of measuring air fuel ratios much more accurately than a factory Narrowband sensor. This enhanced accuracy leads to more accurate tuning and more power and efficiency. The FAST LSU 4.9 sensor is accurate to Air/Fuel ratios as rich as 4:1 and 20:1 lean and is a direct replacement for the sensors provided with the FAST Wireless Air Fuel Meter.

A highly accurate O2 sensor, the Bosch LSU 4.9 is used in our single and dual band wireless air fuel kits under part numbers 170301 and 170302. Compatible with Gasoline, E85, Ethanol, Methanol/Alcohol and Diesel. High max temperature range.
