OEM Versus After Market O2 and MAF

[AHall]

Hello,

I wanted to get some informed opinions on OEM parts versus aftermarket parts, specifically for O2 sensor. Also what about items like sparkplug wires and mass air flow sensors (MAFS). Some sites have indicated that the remanufactured MAFS are superior due to upgrading known failure points.

Thanks for your input.

O2 sensors, spark plugs and MAFs either work or they don't. If they don't work, replace them with a quality replacement.
