What Is the Max Air Flow Bundle for the L5P?
This bundle gives you exactly what we recommend for those looking to get the most out of their truck—without sacrificing reliability. It includes every current HSP Diesel part available for the L5P platform, all at a discounted bundle price.
Cold Air Intake Included in the Max Air Flow Bundle
The HSP Diesel L5P intake is a major upgrade from the factory system. Built from full metal components, it includes a large heatshield that utilizes the OEM ram air scoop. A mandrel-bent intake tube ensures smoother airflow, less turbulence, and up to 20 HP gains without tuning.
Hot Side Intercooler Tube Details
Made from aluminized steel and formed with mandrel bends, this tube maximizes strength and airflow while minimizing turbulence. Includes upgraded 5-ply high-strength silicone boots—offering improved durability and long-term reliability.
Cold Side Intercooler Tube Details
Replaces the weak factory two-piece plastic design with a strong, mandrel-bent aluminum tube and metal adapter. Designed for easy installation and maximum compatibility with OEM components.
