Enlarging the stock New Generation (NG) 900 Turbo airbox inlet tube is easy and allows for far more air to enter the airbox. First off, the stock NG900 Turbo airbox has a 2 inch (51 mm) inlet tube that goes from behind the front right headlight/bumper to the airbox. There is a 2 1/2 inch (64 mm) outlet from the airbox to the turbocharger inlet. Therefore, the 2 inch inlet tube is the first restriction to more airflow.
