Nameless Performance offers a CNC machined billet aluminum replacement for the factory stamped steel part. Utilizing all of the features in the cylinder head to properly align the assembly to the cylinder head using factory dowel holes, as well as an o-ring and plug on the back side of the plate, this system is guaranteed to seal the oil passage in the back of the cylinder head, eliminating the risk of leaks, and eliminating the use of RTV in this area of the oiling system on the vehicle. Excess material has been removed from the panel for an attractive, lightweight solution that does not impact the structural integrity of the part. The surface is anodized in color, laser engraved, and serialized with the Nameless Performance Logo.
