Edelbrock Performer RPM Air-Gap Intake Manifold User Manual
Model: 7566
Introduction
The Edelbrock Performer RPM Air-Gap Intake Manifold is engineered for enhanced engine performance. Manufactured from durable aluminum with a natural finish, this manifold features an exclusive Air-Gap design. This design creates an open space between the intake runners and the hot engine oil, which results in a cooler, denser air charge. A cooler, denser charge contributes to increased power output. This manifold is designed to optimize the power band, shifting it higher for improved performance in the 1,500-6,500 RPM range. It includes provisions for nitrous systems and accepts various accessory brackets, such as those for air conditioning, alternators, and coil mounts.

Important Safety Information
WARNING: THIS PRODUCT CAN EXPOSE YOU TO CHEMICALS WHICH ARE KNOWN TO THE STATE OF CALIFORNIA TO CAUSE CANCER OR BIRTH DEFECTS OR OTHER REPRODUCTIVE HARM. FOR MORE INFORMATION, VISIT WWW.P65WARNINGS.CA.GOV.
Always wear appropriate personal protective equipment (PPE) when handling automotive components. Ensure proper ventilation in your workspace. Consult a professional mechanic if you are unsure about any installation or maintenance procedures.
Setup and Installation
Installation of an intake manifold requires mechanical knowledge and specific tools. It is highly recommended that installation be performed by a qualified automotive technician. Incorrect installation can lead to engine damage or safety hazards.
Pre-Installation Checks:
- Verify that the manifold is compatible with your engine and carburetor type (accepts spread bore or square bore carburetors).
- Ensure all necessary gaskets, bolts, and seals are available and in good condition.
- Note that this manifold does not have an Exhaust Gas Recirculation (EGR) provision. Ensure this is compatible with your vehicle's emissions requirements.
General Installation Steps (Consult a Service Manual for Detailed Instructions):
- Disconnect the battery and drain the cooling system.
- Carefully remove existing components, including the carburetor, throttle linkage, vacuum lines, and the old intake manifold.
- Clean all mating surfaces thoroughly to ensure a proper seal.
- Apply RTV sealant as specified by the engine manufacturer and install new gaskets.
- Carefully position the new Edelbrock Performer RPM Air-Gap Intake Manifold.
- Install and torque manifold bolts to the manufacturer's specifications, following the correct tightening sequence.
- Reconnect all removed components, including the carburetor, vacuum lines, and accessory brackets. The manifold is designed to accept standard accessory brackets.
- Refill the cooling system and check for leaks.
- Reconnect the battery and perform initial engine startup and checks.

Operating Characteristics
Once installed, the Edelbrock Performer RPM Air-Gap Intake Manifold optimizes engine operation by providing a cooler, denser air/fuel mixture to the cylinders. This is achieved through its unique Air-Gap design, which isolates the intake runners from the heat of the engine's lifter valley. The cooler charge improves combustion efficiency and power output.
This manifold is specifically tuned to move the engine's power band to a higher RPM range, typically from 1,500 RPM up to 6,500 RPM, compared to standard Performer Air-Gap manifolds. This characteristic makes it suitable for street and high-performance applications, providing improved acceleration and top-end power.
Maintenance
The Edelbrock Performer RPM Air-Gap Intake Manifold is constructed from durable aluminum and requires minimal specific maintenance beyond general engine care. Regular engine maintenance, as recommended by your vehicle's manufacturer, will help ensure the longevity and optimal performance of all engine components, including the intake manifold.
- Periodic Inspection: Periodically inspect the manifold for any signs of leaks (coolant or vacuum), cracks, or damage. Check the integrity of all hose connections and accessory mounts.
- Gasket Integrity: Over time, intake manifold gaskets can degrade. If you notice signs of vacuum leaks (e.g., rough idle, poor fuel economy) or coolant leaks around the manifold, inspect and replace gaskets as necessary.
- Cleaning: Keep the exterior of the manifold clean to prevent buildup of dirt and debris, which can affect heat dissipation.
Troubleshooting
If you experience issues after installing the Edelbrock Performer RPM Air-Gap Intake Manifold, consider the following common troubleshooting steps:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Engine runs rough, poor idle | Vacuum leak at manifold gasket or hose connections. | Check all vacuum lines and manifold bolts for proper torque. Inspect and replace manifold gaskets if necessary. |
| Coolant leak around manifold | Improperly sealed manifold or damaged gasket. | Ensure manifold bolts are torqued correctly. Replace manifold gaskets and re-seal if needed. |
| Reduced engine performance | Incorrect carburetor tuning, timing issues, or other engine problems unrelated to manifold. | Verify carburetor tuning and ignition timing. Consult a professional for comprehensive engine diagnostics. |
| Accessory bracket fitment issues | Incorrect accessory brackets or mounting hardware. | Ensure you are using standard accessory brackets compatible with the manifold's design. |
If troubleshooting steps do not resolve the issue, it is recommended to seek assistance from a certified automotive mechanic.
