Mishimoto MMAI-MIA-16P Air Intake System

1. Product Overview

The Mishimoto MMAI-MIA-16P Air Intake System is engineered for the 2016 and newer Mazda Miata. This system features an aluminum air box designed for weight reduction and utilizes the vehicle's stock intake duct to efficiently supply cold air to the high-flow air filter. A CNC-machined MAF (Mass Air Flow) housing is integrated to ensure accurate sensor readings and optimal engine performance. The high-flow air filter is designed to improve engine breathing. This air intake system is available in polished, wrinkle black, or wrinkle red finishes.

3.3. Step-by-Step Installation

1. Prepare Vehicle: Open the hood and locate the factory air intake system. Disconnect the negative battery terminal.
2. Remove Factory Airbox: Disconnect the MAF sensor wiring harness. Loosen all clamps securing the factory intake tube and airbox. Carefully remove the factory intake tube, airbox, and filter. Disconnect any vacuum lines or hoses attached to the factory system.
3. Install Mishimoto Air Box: Position the new Mishimoto aluminum air box in the factory location. Secure it using the provided hardware or factory mounting points.
4. Install Intake Pipe: Attach the silicone couplers to the Mishimoto intake pipe and secure them with clamps. Install the intake pipe, connecting it to the throttle body and the new air box. Ensure all connections are snug but do not overtighten.
5. Install Air Filter: Insert the high-flow air filter into the air box and secure it with the provided clamp.
6. Install MAF Sensor: Carefully transfer the factory MAF sensor into the CNC-machined MAF housing on the Mishimoto intake pipe. Ensure the O-ring is properly seated. Secure the MAF sensor with the provided screws. Reconnect the MAF sensor wiring harness.
7. Final Checks: Double-check all connections, clamps, and hoses to ensure they are secure and properly seated. Ensure no tools or debris are left in the engine bay.
8. Reconnect Battery: Reconnect the negative battery terminal.
9. Start Vehicle: Start the engine and listen for any unusual noises or air leaks. Allow the engine to idle for a few minutes. A check engine light may illuminate temporarily as the ECU adjusts to the new airflow; this should clear after a few drive cycles.

4. Operating Instructions

Once installed, the Mishimoto Air Intake System operates automatically with your vehicle's engine. No specific user interaction is required during normal driving. The system is designed to optimize airflow to the engine, potentially enhancing throttle response and engine sound.

• Initial Driving: After installation, drive the vehicle normally for a few cycles to allow the engine's ECU to adapt to the new intake system.
• Engine Sound: You may notice a more pronounced intake sound, especially under acceleration.

5. Maintenance

Regular maintenance of your Mishimoto Air Intake System is crucial for optimal performance and longevity.

5.1. Air Filter Cleaning

The high-flow air filter requires periodic cleaning and re-oiling. The frequency depends on driving conditions (e.g., dusty environments require more frequent cleaning).

1. Removal: Carefully remove the air filter from the air box.
2. Cleaning: Use a specialized air filter cleaning kit (typically includes a cleaner and oil). Follow the instructions provided with the cleaning kit. Generally, spray the cleaner on the filter, let it soak, then rinse with water from the clean side out.
3. Drying: Allow the filter to air dry completely. Do not use compressed air or heat, as this can damage the filter media.
4. Re-oiling: Once dry, apply a thin, even coat of air filter oil to the filter pleats. Do not over-oil, as this can contaminate the MAF sensor.
5. Reinstallation: Reinstall the cleaned and oiled filter into the air box, ensuring it is properly seated and secured.

5.2. System Inspection

• Periodically inspect all clamps, couplers, and hoses for tightness and signs of wear or cracking.
• Check the MAF sensor connection to ensure it is secure.
• Ensure the air box lid (if applicable) is properly sealed.

6. Troubleshooting

If you encounter issues after installing your Mishimoto Air Intake System, refer to the following common troubleshooting steps:

• Check Engine Light (CEL):
  • Cause: Often triggered by an improperly seated MAF sensor, an air leak in the intake system, or the ECU adapting to new airflow.
  • Solution: Verify the MAF sensor is correctly installed and its wiring harness is securely connected. Inspect all clamps and couplers for tightness to ensure there are no air leaks. Disconnect the battery for 15 minutes to reset the ECU, then reconnect and drive the vehicle. If the CEL persists, consult a qualified mechanic.
• Rough Idle or Hesitation:
  • Cause: Can be caused by an air leak, a dirty or improperly installed MAF sensor, or an over-oiled air filter.
  • Solution: Check for air leaks. Ensure the MAF sensor is clean and correctly installed. If the filter was recently oiled, check for excessive oil that may have contaminated the MAF sensor. Clean the MAF sensor with specialized MAF cleaner if necessary.
• Loose Components:
  • Cause: Vibrations during driving can loosen clamps or mounting hardware.
  • Solution: Periodically inspect all clamps, couplers, and mounting points to ensure they are secure. Tighten as needed.
