Preparation

Before starting the installation, ensure that you have all the necessary tools and parts. Make sure to work in a well-ventilated area and wear safety glasses and gloves to protect yourself.

Step 1: Disconnect the Battery

Begin by disconnecting the negative terminal of the battery. This is crucial for your safety as it prevents any electrical shorts while working on the engine.

Step 2: Remove the Old Intake Manifold

Next, remove the old intake manifold. Start by disconnecting any hoses, wires, and components attached to it. Use a ratchet and socket set to remove the bolts holding the manifold in place.

Step 5: Position the Intake Manifold

Carefully position the Mopar Performance 340 intake manifold onto the gasket. Make sure it is properly aligned with the bolt holes and ports.

Step 6: Secure the Intake Manifold

Using your ratchet and socket set, install the bolts to secure the intake manifold. Start by hand-tightening the bolts, then use a torque wrench to tighten them to the manufacturer’s specifications. This ensures that the manifold is secured evenly.

Reconnecting Components

With the intake manifold securely in place, it’s time to reconnect all previously removed components.

Step 7: Reattach Hoses and Wires

Reconnect any hoses, wires, and components that were disconnected during the removal of the old manifold. Double-check that everything is securely attached and in its proper position.

Step 8: Check for Leaks

Before starting the engine, it’s important to check for any potential leaks. Inspect the intake manifold area for any signs of leakage, particularly around the gasket.

Now that everything is reconnected and checked, you can proceed to the final steps of your installation.

Step 9: Reconnect the Battery

Reconnect the negative terminal of the battery. Ensure that it is secured tightly to prevent any issues when starting the engine.

Step 10: Start the Engine

Start your Plymouth Road Runner and let it idle for a few minutes. This will allow the engine to reach its operating temperature. Pay attention to any unusual sounds or issues.

Step 11: Test Drive

Finally, take your Road Runner for a test drive. Monitor the performance and ensure everything is functioning correctly. Enjoy the enhanced power and responsiveness of your newly installed Mopar Performance 340 intake!
