HSP Diesel 3.5" Turbo Inlet Horn for 2001-2004 GM Duramax 6.6L LB7
We at HSP Diesel have designed a massive 3.5’’ replacement unit, that will allow your LB7 Duramax, and its factory IHI turbo charger to consume as much air as possible. The factory LB7 turbo inlet horn is very restrictive. This causes the IHI turbo to not only work harder to pullin fresh clean air, but also hinders spool-up and overall horsepower. With this small addition to your truck, you will see quicker spool-up, and extended turbo life. Many customers reported power gains, and with the addition of the HSP Diesel Cold Air Intake saw a slight drop in exhaust gas temperatures.
This is a direct replacement and does not require any modifications to your truck.
