Disconnect the battery and disconnect the air intake tube from
the throttle body. Drain the engine coolant by loosening the
petcock at the bottom of the radiator. Use a drain pan to collect
drained coolant. Keep the coolant clean and free of dirt and
debris, it can be re-used later

NOTE: On some vehicles, it may be necessary to remove the oil
filter (Remember to re-install BEFORE starting engine) to access
the intake manifold support bracket, and to remove the bracket
from the underside of the vehicle. This simplifies the removal of
the stock intake manifold. The support bracket is not necessary
with the Performer X intake manifold.

Relieve fuel pressure by loosening the banjo bolt connecting the
fuel line to the fuel filter. Place a shop towel or rag over the
wrench while loosening the banjo to soak up any fuel spray

Fig. 1). When loosening or tightening the banjo bolt on the fuel
filter can, use a 19mm
wrench on the hex of the
fuel filter can to
counteract the torque of
loosening or tightening
the banjo bolt. This will
prevent the fuel filter can
and bracket from being
improperly loaded during
loosening or tightening at
the banjo bolt.

If the intake manifold support bracket was not removed
previously, remove the bolts at the rear of the stock manifold
attaching the manifold to the support bracket. Disconnect the
vacuum lines at the rear of the manifold. Remove the throttle
cable. Remove the factory intake manifold nuts. Remove the
stock intake manifold assembly and set aside. If the manifold
support bracket was not previously removed, finish removing the
bracket.

the gasket surface removing any remaining sealant or gasket
material. The gasket surface must be clean and free of any old
gasket material in order to prevent sealing problems.

BEFORE BEGINNING: If you wish to use the Performer X intake manifold with a secondary fuel system, use Edelbrock Secondary Fuel Rail Kit
#4779, and perform the preparation for the secondary fuel rail before beginning the intake manifold installation. The intake manifold must be
removed from the engine in order to install the secondary fuel rail kit.
