88-308-YAM
  • $89.95
Quantity

O2 sensors are used to accurately measure the proportion of oxygen in exhaust gases of combustion engines. This is critical when tuning modified watercraft engines. The wideband lambda sensor LSU 4.9 is a planar ZrO2 dual cell limiting current sensor with integrated heater. The connector module contains a trimming resistor, which defines the characteristic of the sensor and is pre-wired with a connector for PLX Wideband Air/Fuel Sensor Modules and RIVA/LC-1 Lambda Kits. Its advanced design, increased durability and enhanced level of accuracy make the 4.9 the benchmark for all O2 sensors today.

Key Features:

Advanced Wideband sensing element for an exact air/fuel measurement vs. a typical oxygen sensor which simply sends a rich or lean signal.
Robust sensor design increases sensor longevity.
Seared protection tube due to 100% functional quality test.
True Direct-fit' OE connectors and harness; threads pre-coated with anti-seize compound right out of the box.
