This is a reusable/cleanable cotton stock replacement air filter for 1994-2007 Dodge Cummins 5.9L/6.7L and 2001-2010 GM Duramax 6.6L

S&B replacement air filters are made of cotton gauze, so they are easy to clean and perform well even after multiple cleanings. Other companies often use a synthetic material along with cotton in an attempt to stop the dirt. Often times, this results in the dirt becoming embedded in the synthetic material making it very difficult to clean. This results in poor airflow. On the other hand, a properly cleaned, 8-layer S&B Filter can potentially perform better after the first cleaning both in airflow and efficiency.

S&B spent over half of a million dollars on its Climate Controlled ISO 5011 Test Lab to insure that they produce filters that maximize airflow while still protecting your engine from contaminants.
