I’ve used the MD 8222 for 16 years no issue. Recently put a new one in for no reason, old one still fine but I kept it in the car as a spare along with a new bosche blue I bought 16 years ago but never tried
Bought the MSD after seeing this thread and Warren saying he tested them

Whether you can find one locally, not sure
