I had the part numbers but threw it away.
Every Porsche dealer has these numbers in his system.
If you already bought them and you're not sure that you got the right intercoolers, send me a picture. I can identify them immediately.
And if you don't have a Porsche dealer where you can go to (or the dealer is too dumb to search the part numbers for you), tell me. I'll find out the part numbers for you.
