SKU: dmllyat Category:


This is an install kit to put the better flowing Duramax LBZ and newer mouthpiece ( GM PART # 98011738 ) on the 04.5 – 05 LLY.
Unlike cutting and adapting the LLY tube, this makes the system a true 4″ intake and requires no ECM recalibration.
It comes with a black powder coated tube and two automotive couplers and clamps.
Drive-ability is improved as well as quicker spool up.
This kit adds an amazing 35% increase in airflow over the stock LLY components!
Does not include the LBZ mouthpiece.
