Howdy, I have a 2004 Infiniti FX35. I am replacing my camshaft position sensors bank 1 and 2. I notice my current sensors are metal at the ends, and most of the replacements I've found are plastic. Trying to understand the differences between these, because the metal ones are significantly more expensive and I can only find them OEM.

OEM:
23731-AL61D

Left shows what I pulled out of Bank 1 (OEM). Right shows the plastic alternative.



I don't want to make a mistake in installing one that wouldn't work or would cause more problems, so any recommendations is appreciated.

It really shouldn't matter as long as it is the correct part number (or equivalent). I suspect that the metal is aluminium.

My engine wouldn't turn over with the plastic one, but it was used so could have been bad. Ended up just unplugging and replugging all my aluminum ones and reset the ECU after an oil change and my P0021 code went away. Thanks for the input!
