KEEP YOUR COOL

CSF radiators is now offering these new RS- and Rsr-style oil coolers designed for all air-cooled 911s up to 1989. Theyʼre said to be direct-fit performance replacement items in place of the original Porsche parts. CSF says the main benefits involve the heavy duty core, an aero-flow bar design for low mass, strength and maximum airflow through the core itself, along with a satin finish for protection against corrosion and debris. Whatʼs more, the rads feature triangular flush mounting points at both the top and bottom (specifically M8x1.25), and a 15-degree angle for connections (M22x1.5 female) with tapered, cast end-tanks. They measure 609mm x 54.6mm x 146mm, and cost £570 plus VAT. Theyʼre available from www.csfrace.eu
