DHD 400-103 GM Duramax Diesel (2001-2010) Hot Side Intercooler Kit Aluminum

The DHD 3" upgraded intercooler tube represents the next level of air intake products for your Duramax Diesel!

Our ALUMINUM tubes outflow the factory intercooler tube by approximately 35%-40% and are a 100% perfect fit. Unlike our competitors who use steel, our tubes are lighter, more corrosive resistant and mandrel bent for superior flow and lower EGT's.

Advantages to 3"

  • Promotes Greater Cooling Capacity
  • Faster Turbo Spool Up
  • Improves Airflow
  • Lowers EGT's
  • Works with Stock Intercooler and Most Aftermarkets.

The DHD intercooler tube kit includes:

  • 4 Ply Silicone Straight Coupler
  • 4 Ply Silicone 3" to 2.5" Reducer
  • (3) 3" Stainless Steel T-bolt Clamps
  • Raw 3" Mandrel Bent Aluminum Heat Treated Intercooler Tube
  • Brake Hose Relocation Tab
  • Choose from our Standard 4 Ply Reducer or Upgrade to our Reinforced 8-ply Reducer (See options)

Note: DHD's hot side tube is bent to accept a straight coupler at the intercooler inlet. This advancement eliminates the factory 45deg boot that's prone to failure. This change in tube routing will require a brake hose relocation bracket to be installed.
