Cooling: Oversized 9A1 Engine Oil Cooler Porsche 981 Boxster Cayman 997.2 and 991

9A1 engines, like the prior M96 engine, have high operating temps including oil temperatures that can exceed 300F on a summer day on 3.8 models in a DE session. An upgraded oil cooler is a must to help keep engine oil temperatures in control on the track. Our upgraded Genuine Porsche engine oil cooler adds 5 additional plates to the height of the factory 3.8 oil cooler, so 19 plates total!

With the added oil cooler capacity, an upgrade to the cooling system including a low temperature thermostat and a CSF radiators (center as well as upgraded CSF side radiators) will help lower coolant temperatures which directly affects oil temperatures.
