NTC thermistors are non-linear and use a 'correction constant' so that software/electronics can linearise the reading. Porsche state the resistance and sometimes the beta value their sensors in the wiring diagrams. Typically the 'base' resistance is 10k, 15k or 25K usually stated at a particular temperature e.g. 10k at 25 deg C.
Even without this info, the resistance can simply be measured and the beta can be calculated. See here:

Option 1.
Since the only temp you really care about for oil temp is above 90 deg C, you should compare the Porsche and new sensors resistance in hot water at 90 deg C to say 100 deg C. Plot the 2 graphs. If they are the same base resistance and not wildly different then just use the old sensor.
Option 2.
Characterise/calculate the resistance and beta of the new sensor or ask the supplier - they might tell you. Then find another NTC with the same spec and buy it as a PCB component from Mouser - it will look like a small bead capacitor with legs. Drill out the old sensor housing and bond the new sensor into the old housing.
