Banks Power 41829 Ram-Air Oiled Filter for 17-19 Super Duty 6.7L and 20-23 2500/3500 6.6L Duramax

Easy to install replacement filter (oiled or dry). Increased airflow, excellent filtration and longer service life. Banks Ram-Air filter is a high-flow air-cleaner element that decreases intake restriction and sends more cool, dense ram-air into your engine. Even wet or dirty, Banks Ram-Air filters outperform conventional ones, because the multi-layer design traps moisture, dust, and debris on the oiled or dry, outer surface, allowing air to move through with ease.
