2. Safety Information

• Always disconnect the vehicle's battery before beginning any work on the engine to prevent electrical shorts or accidental engine startup.
• Ensure the engine is cool before working on it to avoid burns from hot engine components.
• Wear appropriate personal protective equipment, such as gloves and eye protection.
• Keep all tools and components away from moving engine parts once the engine is running.
• If you are unsure about any step of the installation process, consult a qualified automotive technician.

3. Package Contents

4. Setup and Installation

The installation process typically involves removing the factory air intake system and replacing it with the Rtunes Racing kit. While designed for vehicle-specific fitment, minor adjustments may be required.

General Installation Steps:

1. Prepare Vehicle: Ensure the engine is off and cool. Disconnect the negative terminal of the vehicle's battery.
2. Remove Factory Airbox: Carefully unbolt and remove the existing air intake system, including the airbox, intake tube, and factory filter. Disconnect any sensors or vacuum lines attached to the factory system.
3. Install Intake Pipe: Position the new intake pipe in the engine bay. Use the provided silicone couplers and clamps to connect it to the throttle body and any other necessary connections.
4. Install Air Filter: Attach the conical air filter to the open end of the intake pipe using the provided clamp. Ensure it is securely fastened.
5. Connect Sensors: Transfer the Mass Air Flow (MAF) sensor from the old intake to the new intake pipe. Important: Ensure the MAF sensor is installed in the correct direction as it is directional. Incorrect installation can lead to engine issues.
6. Secure Components: Use the provided mounting hardware (brackets, bolts) to secure the intake pipe to existing mounting points in the engine bay. This prevents vibration and ensures stability.
7. Reconnect Battery: Once all components are securely installed and connections are made, reconnect the negative terminal of the battery.
8. Initial Start-up: Start the engine and check for any unusual noises, air leaks, or warning lights. Allow the engine to run for a few minutes to allow the vehicle's computer to adapt to the new intake.

No additional parts are typically needed for installation beyond what is included in this kit.

5. Operating Principles

The Rtunes Racing Short Ram Air Intake Kit is designed to improve engine performance by optimizing airflow. It replaces the restrictive factory airbox with a less restrictive intake pipe and a high-flow conical air filter. This design allows the engine to draw in a larger volume of air more efficiently. The shorter path of the intake pipe also contributes to quicker throttle response.

The high-flow air filter is constructed with cotton gauze, which provides excellent filtration while minimizing airflow restriction. This combination helps the engine achieve higher explosive horsepower output and a more aggressive engine sound during acceleration.

6. Maintenance

Proper maintenance of your air filter is crucial for sustained performance and engine protection. The included air filter is a dry, washable, and reusable type.

Air Filter Cleaning Instructions:

1. Inspection: It is recommended to check the air filter every 5,000 miles for dirt and debris accumulation.
2. Removal: Carefully remove the air filter from the intake pipe.
3. Cleaning: Wash the filter with soap and water. Gently agitate to remove embedded dirt.
4. Rinsing: Rinse the filter thoroughly with clean water until all soap residue is gone.
5. Drying: Allow the filter to air dry completely before reinstallation. Do not use compressed air or heat, as this can damage the filter media.
6. Reinstallation: Once completely dry, reinstall the filter onto the intake pipe and secure it with the clamp.

This filter does not require oil, which simplifies maintenance and avoids potential issues with Mass Air Flow (MAF) sensor contamination.

7. Troubleshooting

If you encounter issues after installing your short ram air intake, consider the following common problems and solutions:

• Check Engine Light (CEL) / Error Code P0171 (System Too Lean): This code indicates that the engine is running with too much air or not enough fuel. A common cause after intake installation is an improperly seated or incorrectly oriented Mass Air Flow (MAF) sensor. Ensure the MAF sensor is installed in the correct direction and is sealed properly to prevent unmetered air from entering the engine. Also, check for any air leaks around couplers and clamps.
• Poor Engine Performance: If the engine runs rough, idles poorly, or lacks power, double-check all connections, especially the MAF sensor wiring and orientation. Ensure all vacuum lines are reconnected correctly.
• Loose Components/Rattling: Verify that all mounting hardware is tightened and the intake pipe is securely fastened to prevent movement and rattling.
• Whistling or Hissing Sounds: These sounds often indicate an air leak. Inspect all silicone couplers and clamps for proper sealing.

If troubleshooting steps do not resolve the issue, it is recommended to consult a professional mechanic.
