My opinion is NOS Mopar. I had Bosch in the past and they worked great but it seems all manufactures have changed their design. They used to have white ceramic bodies with three wires coming out to the three pin connector, now all seem to have metal bodies with four wires going to the three pin connector. All the recent ones I tested, Bosch, NTK, Omix do not have the correct resistance between A&B, 4 ohms but spec is 5-7 ohms and did not cycle properly based on the REM. See this post
