Wideband O2 Sensor Kit

Good air-fuel ratio data is important to a good tune and ensuring long term engine health. We offer 2 versions of O2 sensors, the Bosch 4.9 LSU and the 4.2 LSU. Either can be had with a stainless steel weld bung, Connector with terminals/seals and a heat shrink boot to make for a cleaned sealed install.

The 4.9" is an 840mm (roughly 33") lead.
The 4.2" is an 630mm (roughly 25") lead.
