    E46 VS E46 M3 Aux Fan

    Anyone know if there are any differences? They look the same but the one for the m3 i can only find genuine for like $600. Rock auto shows the part number for the regular 3 Series will work which i can get aftermarket for under $200. Anyone aware if this will work?

    Someone correct me if I’m wrong, but a quick glance at RealOEM shows two different part numbers. 17117561757 for the non-M and 64546988914 for the M3. The biggest difference appears to be the shroud; not sure if the fan itself is the same. Hopefully someone else can chime in with a definitive answer.

      Shroud is different and won't work without modification, but you can swap just the fan into the M3 shroud.

        Could also use the aux fan failure as an excuse to ditch both stock fans and do a Spal conversion for ~$250 including brackets. I’ve been running a 2082 hooked up to an aux fan controller that I salvaged all year with no issues including in traffic and on track. Just modify the DME fan curve so it turns on 100% by like 85C. I made a thread in coding and tuning and got good answers about how to do it.

              There are no radiator upgrades, stock is best.
