Upgrade your K&N, AFE, Airaid, AEM or Volant intake kit by adding an S&B ISO 5011 Certified, 8-layer filter and achieve better airflow and guaranteed protection (over 99% efficiency).

S&B replacement air filters are 100% cotton gauze (no synthetic media), so they are easy to clean and perform well even after multiple cleanings. S&B's competitors often use a synthetic material along with cotton in an attempt to stop the dirt. Often times, this result 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 actually perform better after the first cleaning both in airflow and efficiency.

S&B spent over 1/2 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 (dirt).
