G&R Diesel | GM LBZ / LMM Duramax Heavy Duty Cold Side Intercooler Tube *DISCONTINUED*

We have developed a heavy duty LBZ-LMM Duramax cold side intercooler tube that replaces the factory tube. From the factory, GM uses a tube with plastic quick connect ends and a light duty intercooler connector. Our tube uses CNC machines billet connectors on each end and a heavy duty 5 ply custom made silicone tube. This not only is much more reliable, but also increases air flow!

Included are 2 CNC machined billet aluminum connectors, 2 sealing O-rings, 2 OEM retainer clips, 2 stainless steel t-bolt clamps and 1 heavy duty silicone boot.

We also sell the billet connectors separately for custom applications! Call 866-895-3833 for more information.
