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 in all 50 states. To assist you with emission equipment certification, we
have included a silver fan shroud decal to help testing personnel verify the this part is a legal replacement on the vehicle
for which it is cataloged. The adhesive-backed decal should be affixed next to the existing emission and engine
specifications decal. Do not cover any part of your original emission decal.
WARNING: The use of "Thermal Wrap" or any aftermarket coating process will void the warranty on your Edelbrock
Headers. Those products will cause excessive heat and moisture buildup resulting in corrosion and failure of the header.
