Banks Ram-Air filter is a lifetime, 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, outer surface, allowing air to move through with ease. Air Filter Element - Oiled, for use with Ram-Air Cold-Air Intake System for use with 2003-2007 Dodge 5.9L
