Description
The Factory LB7 Turbo Inlet Horn Is Very Restrictive, This Causes IHI Turbo To Not Only Work Harder To PUll In Fresh Clean Air But also Hinders Spool Up And Overall HorsePower.
We, at HSP Diesel, have designed a massive 3.5 Inch replacement unit that will allow your LB7 Duramax, and its factory IHI turbocharger 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.

*This was designed as a direct replacement and does not require any modifications to your truck!
