UPR Head Cooling Mod 1996-2004 4.6 5.4 DOHC Modular Engines


     UPR's Billet Head Cooling mod for 1996-2004 4.6/5.4 DOHC 4V Modular engines helps eliminate hotspots in the #8 cylinder. This is achieved by supplying coolant flow around #8 cylinder. #8 Cylinder has been known to be the weak link in naturally aspirated engines let alone performance applications. This will keep you up and running strong by properly supplying coolant to the #8 cylinder.

Installation requires removing the factory freeze plugs to install the UPR Head Coolant reroute kit, and is best done with the engine out of the car. We chose Viton O-rings as they are the strongest most dependable manufacturer of performance O-rings for the aftermarket. This kit includes all parts pictured and there are no other parts required for installation.

Perfect for Stand alone plumbing and performance dry decked cylinder head applications. Designed to Prevent Hotspots in the Rear Cylinders.
