Air Filter Sock Installation

  1. This can be done either when installing the intake for the first time or with it installed onto the car.

  2. If the filter is already installed on the car you'll want to start by undoing the two hose clamps and pop the two tabs in order to remove the airbox lid from the car.


  3. While you can install the sock over the filter while it's installed to the lid, it's definitely easier with the lid off.  To do so remove the six 4mm allen bolts and pop the filter free.


  4. Reinstall and go out and enjoy!  If you run your truck in a dusty environment you'll want to check and clean the filter and sock on a regular interval as clogging can lead to reduced power and less efficient filtration.
