I had one on order for over half year and cancelled it. They said they were waiting for cores. I know a guy who used to work for Denso and still has contacts. We called the other day and were told They are NLA and won’t be produced again. Fortunately if you look hard enough on the internet you can find a Denso one. After the ones on amazon we’re swooped up I looked for days til I found some and ordered a few.
