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 re-
installation.
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

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 3500-
7500 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.
