2020 Duramax Intake

Anyone have word on an intake system for our trucks yet?  This thing with the Derringer could definitely use more air.

The intake won't do anything if you don't change the intake horn.

Who cares how large the air filter and pipe is if the air path necks down right before the turbo.

If you ask me, a stock engine with just a Derringer is not out flowing the stock intake air tubing diameter.

Gale Banks in one of his videos stated that the L5P intake horn is shaped the way it is for a specific purpose and should not be modified.  The Wherli intake in the link above is most probably snake oil and will hurt performance rather than help it.  Some after market mods are good items and some are not.  You have to careful with that you buy into.

If its not Gale Banks designed and or engineered forget it. IMHO.
