Edelbrock’s new Performer cylinder head for 1987-2006 4.0L equipped Jeeps is the ideal performance upgrade. It features a modern combustion chamber design, tuned ports and high quality valves for better flow, as well as reinforced rocker bosses and a thicker 3/4″ deck for strength and durability.
Best of all it is pending 50-state emission legal. These are only a few of the many features engineered into this new cylinder head.
