Cobb Tuning Intake Air Filter Sock for 2017+ Ford F-150 Raptor
[From the manufacturer...]
Wrap it up for extra protection! The COBB Ford Intake Air Filter Sock for the F-150 Raptor 2017-2018 prevents particulates from entering the intake or clogging your air filter.
Whether you're taking your Raptor to the back country, sand dunes, or fireroads, exploring off road terrain can lead to a very gritty air filter. Use the COBB air filter sock to prevent that grit from entering the system.
