1. Product Overview
The DNA Motoring OEM-ITM-002 Upper Intake Manifold is a direct replacement component designed for specific Ford Mustang models. A properly functioning intake manifold is crucial for engine performance and efficiency. Damage to this component can lead to various engine problems, including vacuum leaks, coolant leaks, misfires, and overheating, which can result in costly repairs.
This replacement manifold is engineered to address common failure points found in original equipment. It features a one-piece design with reinforced construction and integrated gaskets to ensure a secure and leak-free seal.
Key Features:
- Direct replacement for the factory manifold.
- Reinforced aluminum coolant crossover to prevent corrosion and vibration-induced failures.
- Re-engineered reinforced plastic construction for enhanced durability.
- Intake gaskets are molded directly into the manifold for improved sealing.

2. Setup and Installation
Installation of an intake manifold requires mechanical expertise and specialized tools. It is recommended that this procedure be performed by a qualified automotive technician. Improper installation can lead to engine damage or safety hazards.
General Installation Steps:
- Preparation:
- Ensure the engine is cool.
- Disconnect the vehicle's battery to prevent electrical hazards.
- Drain the engine coolant.
- Relieve fuel system pressure according to vehicle service manual procedures.
- Remove any components obstructing access to the intake manifold (e.g., air intake, throttle body, fuel rail, wiring harnesses, vacuum lines, coolant hoses).
- Old Manifold Removal:
- Carefully disconnect all remaining hoses, electrical connectors, and fuel lines attached to the manifold.
- Unbolt the old intake manifold from the cylinder heads. Note the location of all bolts.
- Remove the old manifold and discard old gaskets.
- Surface Preparation:
- Thoroughly clean the mating surfaces on the cylinder heads to remove any old gasket material, carbon deposits, or debris. A clean surface is critical for a proper seal.
- Inspect the cylinder head surfaces for any damage or warpage.
- New Manifold Installation:
- Position the new DNA Motoring intake manifold onto the cylinder heads. Ensure the molded gaskets are properly seated.
- Install the manifold bolts. Follow the vehicle manufacturer's specified torque sequence and torque values. Tightening bolts incorrectly can lead to leaks or manifold damage.
- Reconnection and Final Checks:
- Reconnect all fuel lines, vacuum lines, coolant hoses, and electrical connectors that were removed.
- Reinstall the throttle body, fuel rail, and any other components removed during disassembly.
- Refill the engine with the appropriate coolant.
- Reconnect the battery.
- Start the engine and carefully check for any coolant, fuel, or vacuum leaks. Monitor engine temperature and performance.

3. Operating Considerations
Once the intake manifold is installed, proper engine operation is expected. The manifold's primary function is to distribute the air-fuel mixture evenly to the engine's cylinders. After installation, it is important to:
- Monitor engine temperature to ensure the cooling system is functioning correctly and there are no coolant leaks.
- Listen for any unusual engine noises, such as hissing (indicating a vacuum leak) or misfires.
- Observe engine performance during various driving conditions to confirm proper air-fuel delivery.
4. Maintenance
The DNA Motoring OEM-ITM-002 intake manifold is designed for long-term reliability. Regular maintenance of your vehicle's engine and cooling system will contribute to the longevity of the manifold. Key maintenance practices include:
- Periodic Inspection: Regularly inspect the manifold and surrounding components for any signs of leaks (coolant, vacuum) or cracks.
- Hose and Connection Checks: Ensure all vacuum lines, coolant hoses, and electrical connectors attached to the manifold are secure and in good condition.
- Coolant System Health: Maintain proper coolant levels and ensure the cooling system is free of contaminants to prevent corrosion, especially around the aluminum crossover.
5. Troubleshooting
If you experience issues after installing or during the use of the intake manifold, consider the following common symptoms and potential causes:
| Symptom | Possible Cause | Action |
|---|---|---|
| Coolant Leaks: Puddles under vehicle, low coolant level, engine overheating. | Improperly torqued manifold bolts, damaged gasket, crack in manifold, loose hose connections. | Inspect manifold and hose connections. Check bolt torque. If manifold is cracked, replacement is necessary. |
| Vacuum Leaks: Hissing sound, rough idle, engine misfires, poor fuel economy, check engine light. | Improperly seated manifold, damaged gasket, loose vacuum lines, crack in manifold. | Inspect manifold for proper seating and vacuum lines for secure connections. Professional diagnosis for vacuum leaks is recommended. |
| Engine Misfires/Reduced Performance: Rough running, lack of power, check engine light. | Severe vacuum leak, internal manifold issue affecting air-fuel distribution. | Consult a qualified technician for diagnostic testing. |
For persistent or severe issues, it is always recommended to consult a qualified automotive technician for proper diagnosis and repair.
