Specifications
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, outer surface, allowing air to move through with ease.
