Thank you for the reply.
But I am looking for the Alfa part number. I live in Costa Rica and I need to buy the part online and not all online stores ships to US or Costa Rica.
I need the piece as as possible as my car is not working right now and the part is not available in the only Alfa dealer in CR and the price here is extremely high (about 500 $) so I will buy in Internet and have it shipped to a freight forwarder in the US.
I had already bought some parts that way and I save a lot of money compared to local prices.
My engine number starts with: AR32301 and the VIN starts with : ZAR9320002
Alfa Romeo 156 2.0 TS 2002
