The Corsa 46557-1 MaxFlow 5 Closed Box Air Intake is purpose-built for the 2019 and newer Ram 1500 DT-platform trucks equipped with the 5.7L HEMI V8. Unlike earlier Ram intakes, the 46557-1 is engineered specifically for the redesigned 2019 and newer engine bay layout, ensuring correct fitment and maximum performance on the new-generation 1500. Corsa's cross-linked polyethylene sealed housing blocks hot underhood air, while the MaxFlow 5 five-layer oiled cotton gauze filter delivers 98 percent filtration efficiency and a 26 percent airflow improvement over the factory airbox.
