JJ-CCR oxygen sensor more than 3 months

JJ sensors are described in the manufacturer's instructions as suitable for use only up to 3 months after their manufacturing date. However, provided the sealed bag containing them remains unopened, the sensors are suitable for use for up to 1 year after their manufacturing date.

Due to this discrepancy between the instructions and actual effectiveness, we have to offer all our remaining sensors old than 3 month at a lower prices. These sensors are guaranteed by us to function perfectly throughout their lifespan, at less 12 months...

The current batch of sensors are of: 2025 August
