Flame retardant and pre-oiled filter for Power Flow Kit.The same features as the Original filter, with the added convenience of wash-down-the-drain cleaning. A Dual-Stage Air Filter is submerged in BIO Liquid Power Filter Oil, massaged to ensure all pores are evenly coated, and placed in a temperature-controlled room to allow the oil to completely cure. You just open the resealable bag and installTwin Air’s breakthrough, fused-dual-layer design (now widely copied) combined performance and protection. The fused layers of open-pore foam and fine inner foam trap even the smallest particles. The new, rounder design boosts airflow. So do the minimized seams made possible by a revolutionary micro-gluing process: Shorter seams = more foam = more flow.Coarse open-pore foam catches airborn dirt, grime and sandFine open-pore inner foam acts as second filter to trap the smallest particles while ensuring maximum air passageAdhesive withstands repeated cleaning
