Billet ZL1 Coolant Manifold

For years, the only method for converting the ZL1 inlet/outlet coolant ports to -12an was to machine and weld the factory cast aluminum piece. After proving this process on over 6000 OEM pieces we decided to bring this billet version to market. This manifold comes standard with -12 ORB threads and can accept a -12 ORB adapter. The billet version CNC machined from 6061 aluminum and hard anodized for a long life in the harsh environment of the LSA cooling system. The beauty of this design is if you damage the threads or the sealing surface, the ORB fitting can easily be replace.
