Installed 3" Cold Air Intakes... AND My G37 Hated It!

Installing a 3” Cold Air Intake on a G37 is NOT as simple as it sounds. In this video, I install the Z1 3” Cold Air Intake Kit on my Infiniti G37 (VQ37VHR) — and the car almost became a paperweight before we fixed it with a proper tune. If you're searching for: G37 cold air intake install Z1 3 inch intake review VQ37VHR intake upgrade G37 intake requires tune G37 rough idle after intake This video will save you time and potentially a headache. In this episode of the Blue Ice Project, I walk through: ✔ Full Z1 3” Cold Air Intake install (step-by-step) ✔ Removing factory airboxes and MAF sensors ✔ Cutting for larger intake piping ✔ Why the G37 ran poorly after install ✔ Why a tune is required for 3” intakes ✔ Final startup and intake sound comparison The Infiniti G37 VQ37VHR platform responds well to airflow upgrades — but when you increase piping diameter to 3 inches, the factory tune can struggle with airflow scaling. That’s what happened here. Lesson learned: more air requires proper tuning. Next episode: exhaust install + tuning update.
