Intake (LLY)

Duramax LLY trucks are notorious for having a restrictive intake system on them.  These cold air intake systems are exactly what you need to let your Duramax LLY breath the way it needs to.  This helps your LLY Duramax run cooler EGTs and the turbo to spool quicker.  Can you can't go wrong with any of these cold air intakes!
