DESCRIPTION: These components are designed to improve the exhaust efficiency of the Ford 5.4 Litre V8 engine. This system does
not require welding for installation and retains all O.E.M. emissions equipment. These Edelbrock headers are street legal in all 50
states. These systems should be installed by an experienced/qualified mechanic.
Suggested tools needed for installation: This vehicle has some metric fasteners.
❑ 3/8" ratchet socket set with extensions and universal 13mm and 15mm swivel sockets

❑ Jackstands, screwdrivers, pliers, crescent wrench, etc.

SPECIAL NOTICE: This Edelbrock part has received an Executive Order number (E.O. #) from the California Air Resources Board
(C.A.R.B.) making it legal for street use on pollution-controlled motor vehicles in all 50 states. To assist you with emissions equipment
certification, we have included a silver fan shroud decal to help testing personnel verify that this part is a legal replacement part on
the vehicle for which it is cataloged. The adhesive-backed decal should be affixed to your fan shroud next to the existing emission
and engine specification decal. Do not cover your original equipment specification decal with the Edelbrock fan shroud decal.
WARNING: The use of “Thermal Wrap” or any aftermarket coating process will void the warranty on your Headers. Those products
can cause excessive heat and moisture build up resulting in corrosion and early failure of the system.
