why this one — Listed directly on aFe's own F-150 3.0L Power Stroke vehicle page - a protection/cooling upgrade rather than a power part, useful for a diesel truck likely doing real towing work. $299.25 confirmed 2026-07-23. A Pro Series version (46-71180B, $344.40) is also available.
No power claim - cooling/protection component.
