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 has required options. 2021 and later plenums use standard socket head cap screws, prior to 2021 the plenums use countersunk hardware. If you select the countersunk hardware option it will NOT come with orings or spacers.
