Dual-pass coolers are a great option for street rodders and have all the benefits plus the good looks us truckers prefer. This good-looking unit is a nice example; it’s a finned aluminum dual-pass Specialty Auto cooler offered by Cool Craft. The neat thing about coolers such as these (above and beyond their great looks) is they really are sturdily constructed and will stand up to punishment like flying road debris – plus they’re designed to work with any type of fluid like ATF, engine oil, coolant or power steering fluid. The heat-sink design and both internal and external cooling fins transfer heat even in situations where there’s restricted airflow. These babies are available in six sizes, from 12 inches long to 24 inches.
