aFe's Magnumflow wet airfilter element for the OEM stock airbox provides the maximum flow possible. We do not sell intake kits for the IS-F that eliminate the stock airbox, because they do not work! Beware of dyno graphs showing power gains from IS-F intake systems, the gains are temporary due to inadvertent airflow scaling changes imposed by these intake "systems."
