These billet adapters replace the factory coolant connections at the front of each Coyote cylinder head with a threaded ORB port. They let the coolant hose run where the build needs it. They suit dry-decked Coyotes, and also engines that are not dry decked but need the plumbing routed around headers, a front mount, or a turbo setup with little room at the front of the engine.
The adapters are CNC machined billet with a hard black anodized finish, and stainless steel hardware is included. The two sides are different sizes. The driver side accepts a -16 ORB adapter fitting and the passenger side accepts a -12 ORB adapter fitting. The adapters are ports only, so ORB to AN adapter fittings are needed separately.
Fitment is split by head casting, not by the year on the registration. The split falls at the 2015 head casting change. The 2015 adapter fits Gen 2, Gen 3 and Gen 4 Mustang through 2026, including Darkhorse. On a swap or a used long block, order against the heads actually on the engine.
