CSF is a leader in automotive cooling technology, with over a half-century of experience. Using that knowledge, they have developed this high-performance power steering cooler that far surpasses the abilities of the stock unit. Starting with a six-row, dual-pass design with 83% more surface area than the stock part, this power steering cooler features high-quality CAB (controlled-atmosphere brazing) assembly versus the mechanically bonded core of the stock part for increased durability. Best of all, it fits like the stock part, with plenty of clearance for aftermarket supercharger setups despite being lab-tested at 40% more efficient than the stock cooler. If you're serious about performance, upgrade your power steering cooler with this quality part from CSF.
