2001-2004 Duramax LB7 HSP Diesel Cold Air Intake (102-HSP)

The 102-HSP, or the HSP Cold Air Intake, is specifically designed for the 2001-2004 LB7 Duramax-equipped Chevrolet and GMC trucks. This drop-in style intake not only performs at a high level but also enhances the engine bays appearance.

Why You Need the HSP Cold Air Intake for the LB7
The factory LB7 intake leaves much to be desired. Its restrictive, outdated, and doesnt deliver the performance that modern diesel enthusiasts demand. HSP Diesel designed this intake to install easily, look impressive, and”most importantly”deliver the high-performance airflow your turbocharger deserves.

What Makes the HSP Cold Air Intake Different?
The centerpiece of this intake is the massive 4 1/2" mandrel-bent tubing that ensures optimal airflow with minimal turbulence. This smooth and wide pathway allows cooler air to flow freely into the turbo, promoting better spool-up and lower temperatures. Complementing this is the HSP-designed heatshield box, which is hand-fitted for precision and built to isolate the filter from hot engine bay air. Unlike some intakes, the heatshield box does not draw from the headlight bezel or fender port, ensuring maximum cold air delivery. Topped off with a high-efficiency filter, the system keeps air clean to reduce turbo wear and extend service life.
