The COBB Tuning Replacement Filter is available for those of you who need a direct replacement for damaged, or misplaced filters. These filters have been designed to last the lifetime of your vehicle, and can be washed, oiled, and serviced for continued use. However, if your filter got damaged by an accident, or other circumstances they are available for separate purchase to renew your SF intake or if you have a custom cold air intake and need a premium filter, this will also get the job done.
