Review on GPP Gloss Black High Flow Intake Elbow Turbo Inlet πŸš€ Horn | Compatible with 2001-2004 GM 6.6 LB7 Duramax Diesel Engine by William Dean

Revainrating 4 out of 5

Works and looks good but very difficult to install.

Installation on a 2004 Chevy 2500 HD is very difficult. Allen had to make an elongated ball. They should charge extra and ship the right gasket and tool. However, after installing it, I noticed a difference. The turbine spins faster. My tuner said that from 0 to 60 also caught. Also looks nicer than the factory. Update: Looks like it might save a few mpg of fuel on my truck. I suspect because it improves EGT and turbo winding.

Pros
  • Nice packaging
Cons
  • Some difficulties
