Admission d'air froid pour Nissan 370Z (2009-2019) moteur 3,7 L - Noir

The Wrench Time

• Estimated Time: 90-120 Minutes
• Difficulty: 5/10 - Dropping the Z34 front fascia for a true cold air intake routing is tedious, but completely manageable for a driveway warrior. You are doing the work twice for the VQ37VHR twin-intake system.

Tools You Will Need

• 10mm deep socket with a 6-inch extension (for battery, airboxes, and hidden fascia bolts)
• 8mm socket or nut driver (for hose clamps)
• Panel popper tool (for factory push-pins)
• #2 Phillips screwdriver (JIS standard preferred for factory MAF screws)
• 3mm or 4mm Allen wrench (for aftermarket MAF hardware)

Phase 1: Removing the Factory Part

1. Disconnect the Battery: Always start by disconnecting the negative battery terminal on your 2009-2019 Nissan 370Z 3.7L using a 10mm wrench to prevent check engine lights.
2. Drop the Front Fascia: Using your panel popper, remove all the plastic push-clips along the top radiator shroud and underneath the belly pan. Pull back the front wheel well liners to access and remove the hidden fender bolts using your 10mm socket and extension. Carefully unclip the bumper and set it aside on a soft blanket.
3. Detach the Corrugated Tubes: Loosen the factory hose clamps at the throttle bodies and the airboxes using your 8mm socket. Disconnect the PCV breather hoses from both intake tubes.
4. Remove the Factory Airboxes: Unbolt the driver and passenger side airbox housings from the core support using your 10mm socket. Lift the bulky factory dual-intake assembly entirely out of the Z34’s engine bay.
5. Extract the MAF Sensors: Carefully unscrew the Mass Air Flow sensors from the factory housings using your #2 Phillips screwdriver. Gently pull them straight out and set them somewhere safe in a clean zip-lock bag.

Phase 2: Installing the Cold Air Intake for Nissan 370Z (2009-2019) 3.7L Engine - Black

1. Transfer the MAF Sensors: Gently insert your factory MAF sensors into the new black aftermarket intake tubes. Secure them using the provided hardware and your Allen wrench. Ensure the factory O-rings are seated completely flush to prevent the vacuum leaks that frequently plague VQ37 builds.
2. Route the New Piping: Slide the provided silicone couplers onto the dual 3.7L throttle bodies. Carefully thread the new aluminum cold air tubes down through the core support openings so the ends sit right in front of the crash bar.
3. Secure the Clamps and Brackets: Fit the tubes into the throttle body couplers and snug the worm-gear clamps using your 8mm socket. Align the welded intake brackets with the factory mounting points and tighten them down using your 10mm socket.
4. Mount the High-Flow Filters: Attach the pod filters to the ends of the tubes sitting behind where the grille will be. Tighten the filter clamps securely with your 8mm socket. Reconnect the PCV breather hoses to the new tubes.
5. Reassemble and Learn: Reinstall the front fascia by popping all factory clips back into place and securing the hidden fender bolts with your 10mm socket. Reconnect the battery. On the very first startup, the vehicle gas pedal should not be touched for 20 seconds. Let the car idle so the ECU can adjust to the drastically increased airflow.
