Step-by-Step Installation Guide
Step 1: Prepare Your Vehicle
Before starting the installation, ensure that your vehicle is parked on a flat surface and the engine is cool. Open the hood and disconnect the negative battery terminal to prevent any electrical issues during the installation.
Step 2: Remove the Factory Air Intake
Locate the factory air intake system. This typically involves removing the airbox cover and disconnecting any hoses or clamps securing the intake. Use your socket set to remove any bolts holding the airbox in place.
Step 3: Install the New Cold Air Intake
Take your new cold air intake and position it where the factory intake was located. Secure it using the provided hardware. Make sure all connections are tight and that the intake is properly seated to prevent any leaks.
Step 4: Connect the Intake Tube
Attach the intake tube to the throttle body. Ensure that it is aligned correctly and secure it with the provided clamps. Double-check that all connections are tight.
Step 5: Reinstall Any Removed Components
If you removed any components during the installation process, such as the airbox cover or hoses, reinstall them now. Make sure everything is back in its original position.
Step 6: Reconnect the Battery
Once everything is securely in place, reconnect the negative battery terminal. This will restore power to your vehicle.
Step 7: Test the Installation
Start your engine and let it idle for a few minutes. Listen for any unusual sounds that may indicate a problem. Take your car for a test drive to experience the difference in performance.
Conclusion
Installing a cold air intake on your Infiniti G37 can significantly improve performance and driving experience. By following these steps, you can enhance your vehicle’s power and efficiency, potentially gaining up to 20 horsepower. Always remember to consult your vehicle’s manual and follow safety precautions during the installation process.
