CORSA Performance Dryflow 3D Air Filters maximize power and filtration performance while reducing maintenance. Using specialized hydrophobic polysynthetic fibers, CORSA Performance Dryflow 3D Filters boost filtration capacity lengthening time between maintenance intervals up to 50K miles depending on driving conditions. By vastly increasing media depth through unique pleating geometry, each filter traps more particulate than traditional cone style filters allowing you to drive further before requiring service. Additionally, Dryflow 3D Filters reduce maintenance time by resisting saturation that occurs during washing, dropping drying time to as little as 2 hours. For an even faster clean, vacuum off surface particulate to restore filter performance.
