HEADERS: These components are designed to improve the exhaust efficiency of the Dodge 3.9 Litre V6 engine with E.F.I.
(Electronic Fuel Injection). These tubular manifolds are a direct replacement for the factory exhaust manifolds. A
performance gain can be expected by the installation of this system. This system does not require welding for installation
and retains all O.E.M. emissions equipment.
SUGGESTED TOOLS FOR INSTALLATION:
❑ 3/8" ratchet socket set with extensions and sockets
❑ Jackstands, screwdrivers, pliers, crescent wrench, etc.
❑ Combination set of open-end wrenches
❑ Liquid penetrant, anti-seize compound
SPECIAL NOTICE: This Edelbrock part has received an Executive Order (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 buildup resulting in corrosion and early
failure of the system.
NOTE: High temperature spark plug wires and boots are recommended to withstand heat from Headers.
IMPORTANT NOTE:
Proper installation is the responsibility of the installer. Improper installation will void warranty and may
result in poor performance and engine or vehicle damage.
