That is an interesting comment -thank you. I thought that since it was the latest version ,it would be and improvement in de-foaming.
Even more strange ,the 987 parts came as part of the deep sump kit I mentioned. so the kit manufacturer went to all the trouble of supplying the later part with the intention that you dump the old defoamers.
here is a link to the kit:
2001 Porsche Boxster S Convertible - Oil Circulation - Page 3
Here is the original part number :
99610708054
The upgrade is the same as an '06 997. Sorry I had typed 987 above.
This ad has a photo of both the old and the new design.
Huge difference in design/size.
