Billet Coolant Neck

A nice aesthetic upgrade over the OEM, gaskets included.

★ Billet Aluminum Construction
Machined from aluminum for improved strength and long-term durability.

★ Improved Reliability
Handles heat cycles better than OEM plastic housings. Helps reduce the chance of leaks or failures in a common weak point.

★ OEM-Style Fitment
Designed to work with factory hoses and mounting points, so install stays straightforward without needing to modify anything.
