GM 3.0L Duramax Airbox Silicone Coupler

Coupler replaces the accordion pipe from airbox to intake tube. Tube is thick and rigid which can make installation difficult. Use soapy water or a little bit of oil to aid in fitting the pipe accordingly. Fit to the intake pipe first, then clock the coupler to the correct position, and finally installing the airbox lid. Removing the accordion pipe greatly reduces movement and makes installing the lid more difficult but not unmanageable. Benefits are smoother airflow by reducing turbulence within the intake system.

Properly replaced the factory hose and removed the check engine light that was there after replacing the intercooler and zilla carbon fiber intake.
