The CSF 8258 replaces the plastic-shrouded factory units with a 100% all-aluminum TIG-welded design that eliminates the failure-prone OE mounting pod. By integrating the mounting points directly into the modular tank design, CSF increased the core size by 6.4% and tank volume by 10% within the same factory footprint.
