Product Details

We, at HSP Diesel, have designed a massive 3.5 inch replacement unit that will allow your LB7 Duramax, and its factory IHI turbo charger to consume as much air as possible. 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.

The factory LB7 Turbo Horn is very restrictive. This causes the IHI Turbo to not only work harder to pull in fresh clean air, but also hinders spool-up and overall horsepower.
