...This is a BEHR Front Mounted Oil-Cooler as used on the 2.8 liter 1973 Porsche 911 RSR as well as the 914-6 GT race cars. The mounting brackets are used on the 911 RSR application and will have to be removed when used with the steel ducting/shroud of a 914-6 GT. I believe that this BEHR oil-cooler was also used on other Porsche race cars (904/906).

Unless I'm reading the BEHR label incorrectly, this oil-cooler may have been manufactured sometime in 1973 (see label photo below)l
