many sites have huge errors. I just found one of the top makers of thermostats (2 diff co.s were both wrong)
This is not rare.
best it to decide what part you want and what brand, or OEM.
you can see the diffs , here
https://www.trademotion.com/partloca...?siteid=214330
see part and year of applic.
best deal on o2 is , find the Brand and PN first, never trust anyone on Fleebay to sell you the correct parts, find out yourself then order by exact pn.
OEM or other wise,.

please do go to Bosch and look up your car. ( never trust my pn, as it could change)
