Riffraff Diesel Billet Plenums Replacement Reinstall Kit 

This kit is for replacement of your kit that was included when the plenums were purchased originally. You do not need to purchase this kit if you are purchasing the plenum as these are only for replacement.

NOTE: This kit only applies to the 2021 and later billet plenums. Plenum kits made before 2021 used different hardware that we no longer have to offer.
