This adapter replaces the original oil fill cap on the driver's side of the engine. It is CNC-machined from billet aluminum for precise fit, and the included silicone O-ring is specially designed to prevent oil seepage at the base of the adapter.
The top of the adapter is machined to accept a #10AN hose end to facilitate the installation of a custom crank case evacuation system, PCV system, or for use with a vacuum pump.
Total adapter length is 2.10".
Various Mopar Applications, Including 2008 & Newer 5.7, 6.1, & 6.4L Hemi with Screw-in Oil Cap
Note: This adapter will fit all Mopar applications using the screw-in style oil fill cap. It will not fit models like the 2015 & newer that use the helix-style twist-in threads. An adapter for this twist-in application is listed elsewhere in this section.
