After studying what was currently available on the market for the Audi B5 S4 platform – CSF spent quite a bit of time perfecting the design after the initial prototype. CSF made sure to include machined OEM-style “Quick-Connect” inlet/outlet fittings, as well as machined installation seating areas on the top of each tank that holds the rubber bushing pads for correct and study fitment with no vibrations and no modifications necessary to install. Just another extra step that CSF has taken to continue to make the best cooling products in the world.
