AMS Evo X 4B11 Cam Cap (AMS.04.04.0013-1) *Discontinued*

The AMS Performance Evo X 4B11 Billet Cam Cap was designed after reports that the OEM piece was cracking. In order to replace the OEM piece, the entire cylinder head would need to be purchased new from Mitsubishi as it not sold separately from the stock 4B11 cylinder head!

AMS now offers this 4B11 cam cap as a perfect solution to replacing the original without having to purchase the entire cylinder head. The billet aluminum cam cap is CNC machined, etched with the AMS logo and designed using SolidWorks CAD software.
