Dress things up under your hood of your LML Duramax by adding this anodized black PCV reroute cap. This cap is machined from aluminum and anodized black to give is a nice and clean look when installed. They come with an o-ring installed to insure proper fitment and to keep debris out of your intake system.
NOTE: This will only fit 2011 LML. 12-16 will have both ends rounded. You will need 007-7123.
