Remanufactured? Considered it. I bought the OEX as my original died on a Saturday night and not to many options available on a Sunday. When the OEX started showing problems I asked around and re-manufactured units use aftermarket parts (from china). I think the issue with the OEX is that the regulator is not compatible with the Honda ECM signal and therefore could not regulate the demanded current. I thought the same may occur with replacement parts so decided on the new Denso.
