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.

3. Disconnect the fuel injector wiring harness from the bracket on the
fuel rail and unplug the harness from the fuel injectors.

NOTE: Mark sensor connectors before removal. Some sensors
have same plug ends. Make note of the locations of each plug
on the harness to prevent improper connection during re­installation.

FACTORY INTAKE MANIFOLD REMOVAL AND DISASSEMBLY

1. 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.

2. 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

INSTALLATION INSTRUCTIONS

PLEASE study these instructions carefully before beginning this installation. Most installations can be accomplished with common tools and

procedures. However, you should be familiar with and comfortable working on your vehicle. If you do not feel comfortable performing this installation,
it is recommended to have the installation completed by a qualified mechanic. If you have any questions, please call our Technical Hotline at:
1-800-416-8628, 7:00 am - 5:00 pm, Pacific Standard Time, Monday through Friday or e-mail us at [e-mail]

.

IMPORTANT NOTE: Proper installation is the responsibility of the installer. Improper installation

will void your warranty and may result in poor performance and engine or vehicle damage.

DESCRIPTION: The Performer X intake manifold is designed for the Honda D16Z6 engine in the 1992-1995 Civic EX/Si. The throttle body mounting

flange has been angled to help clear stock componentry, yet allow the integration of 9” runners and a larger plenum for best performance in the 3500­7500 rpm range

(NOTE: Minor modifications to your air intake tube may be required)

. The Performer X intake manifold also includes four (4) secondary
fuel injector bosses for turbocharged or alcohol fuel applications. These are partially machined and may be drilled through if you wish to use a
secondary fuel rail and injectors (Edelbrock Part #4752). The Performer X manifold utilizes a 62mm throttle body opening to accept oversize throttle
bodies without port matching.

EMISSIONS SYSTEMS: The Performer X intake manifold is intended as a direct replacement for the factory intake manifold. All emissions related
factory components are to be retained and functional. The manifold is, therefore, legal for street use in all 50 states, and no C.A.R.B. E.O. number is
required. Check local laws for requirements.

RECOMMENDED PARTS: The following are recommended but not required for use with the Performer X intake manifold:

1. Edelbrock Pro-Flo Fuel Rail Kit - Part # 4794

2. Russell Stainless Steel Fuel Line Kit - Part # 641120

3. Edelbrock Secondary Fuel Rail Kit - Part # 4752
(For applications requiring additional injectors)

INSTALLATION PROCEDURE

KIT CONTENTS:

❑ 1 Performer X Intake Manifold

Install the vacuum fittings into the top of the Performer X intake
manifold

(See Fig. 2-B)

.

Install the water outlet fitting into the mounting flange and install the
1/8” NPT x 8mm barb into the water outlet fitting

(See Fig. 2-C)

.

2. Remove Idle air control motor from factory intake manifold and
install onto the Performer X intake manifold

NOTE: If the vehicle is equipped with the IAC motor mounted
on the throttle body instead of the intake manifold, install the
supplied IAC Cover Plate using the two supplied 8mm x 1.25 x
20mm bolts and the supplied gasket. Leave the IAC motor
installed on the throttle body.

Remove the throttle body, and two throttle body studs from the
factory intake manifold. Using two nuts on each stud, and jamming
them, will help get the studs out of the stock intake manifold

(See

Fig. 3)

. Install the two throttle body studs into the Performer X
intake manifold, one on the upper right bolt hole of the throttle body
mounting flange and one on the lower left bolt hole. Install the stock
throttle body onto the Performer X manifold. Install the supplied
throttle bracket onto the Performer X manifold using the stock bolts.
Remove the stock fuel
rail, fuel injectors, fuel
pressure regulator, fuel­rail-studs and spacers
and install onto the
Performer X manifold
using the OEM hardware.
Inspect all o-rings and
seals for wear and
replace if necessary.

Disconnect the Throttle Position Sensor and Idle Air Control Motor
connectors. Disconnect the PCV valve hose from the intake
manifold. Disconnect the fuel return line from the steel chassis fuel
line. Disconnect the fuel line from the fuel filter. Disconnect the
coolant lines from the throttle body and manifold flange.

NOTE: Some coolant will drain from the coolant lines leading
into the intake manifold when they are disconnected

.

Remove the two bolts at the rear of the stock manifold attaching the
manifold 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. You may now remove the stock intake manifold
support brace.

4. Stuff the open intake ports in the cylinder head with paper towels to
prevent any debris from entering the engine. Thoroughly clean the
gasket surface removing any remaining sealant or gasket material.
