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 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 Tubular Exhaust System.
Those products can cause excessive heat and moisture buildup resulting in corrosion and early failure of the system.
NOTES: High temperature spark plugs wires and boots are recommended to withstand heat from T.E.S.
