Install and warranty notes: Mount it where it sees a representative exhaust sample, as close to vertical as practical with the wiring facing up, and away from the tailpipe end where fresh air skews readings. Protect it from condensation and excessive exhaust heat. Bosch's warranty excludes aftermarket use, so Link provides no warranty on the LSU 4.9 sensor.
