Porsche part equivalent
 

I am aware that Porsche sources many car parts from other brands: BMW, Audi, and VW to name 3. For instance, the lifters used in my 986 S are apparently the same as found in the BMW parts bin. My question is, does anyone know of a list or resource to find the equivalent part number? For example, the lifters at Porsche are part number 99610504172, so the corresponding BMW # would be .....
Thanks for any info you might have! :)

BMW part numbers
 

Go to realoem.com

Thanks, but this doesn't give me the equivalent part number. I would need to already know the BMW part.

Didn't know about the BMW parts, thought it was mostly VW/AUDI. I usually find that when a part doesn't start with 986/996 there's a good possibility it's a generic or VW/Audi part. But that's my rule of thumb.
