Banks Air Filter for Ram-Air® #42172 and #42172-D | 07.5-10 GM 2500HD/3500 6.6L Duramax LMM

This Banks air filter is designed for use with their Ram-Air® cold air intake systems #42172 and #42172-D. It is a high flow air cleaner element that decreases intake restriction and sends more cool, dense air into your engine. Banks Ram-Air® filters outperform conventional ones, because the multi-layer design traps moisture, dust and debris on the outer surface, allowing air to move through with ease.
