Sold Dec/08/2009. Porsche 911 S/T 911 T/R Racing Oil-Filler Neck NOS Werks

Now, this IS a very rare Porsche racing part, a 911 S/T and 911 T/R "NOS" Racing Oil-Filler Neck only used in "racing" applications. Take a good look at the filler neck, note the provision for a "pressure relief valve" https://pbase.com/9146gt/image/102523198 - A pressure relief valve is NOT found in a normal street 911 car, only race cars (p/n 901.107.640.033).
