UPR 5.0 / 5.2 Ford Coyote Billet Head Cooling Mod Triple O-Ring Seal

The UPR Billet Head Cooling Mod is engineered for 2011-2023 Ford 5.0L Coyote and 2015-2022 Ford 5.2L Coyote GT350 and GT500 engines to improve coolant circulation around the rear cylinders, helping eliminate hot spots at the #8 cylinder. By supplying additional coolant flow to the back of the cylinder head, this system addresses one of the most common cooling concerns found in high-performance Coyote engines, improving reliability in naturally aspirated, supercharged, turbocharged, and racing applications.

Manufactured from black anodized billet aluminum, this bolt-in cooling modification features UPR's triple Viton O-ring sealing design to provide exceptional leak protection while eliminating the potential for freeze plug failures. The kit includes premium UPR AN fittings, a durable steel braided hose, billet cylinder head fittings, and all required mounting hardware for installation. It is also ideal for standalone plumbing systems and dry-deck cylinder head applications. Installation requires removal of the factory freeze plugs and is recommended with the engine out of the vehicle.
