True Flow Sealed Air Intake Systems are a unique departure from traditional air intake systems.

True Flow Air Filters are more than 12 times thicker than the competitor's gauze or paper filters, giving foam filters superior filtration and overall airflow. Foam filters are constructed of tiny interlocking cells that distribute and trap dirt particles throughoutthe entire volume of the foam.

As your True Flow foam filter gets dirtier, it actually flows moreair than a gauze filter giving you improved performance and mor ...
