Part Number: 481-HSP

What Is the HSP Cold Air Intake Bundle for the LMM?

This bundle brings together the key components needed to maximize your cold air intake setup. It's designed to ensure you're getting the most out of your engine's potential with improved airflow and efficient thermal management.

Cold Air Intake

While the LMM engine is strong out of the box, the factory intake is restrictive. HSPs 4.5" mandrel-bent intake tubing drastically improves airflow and reduces turbulence. The HSP heatshield minimizes hot air draw from the engine bay, resulting in cooler, denser air and more power. The system also includes a high-quality air filter to ensure clean air delivery.

VGT Intake Mouthpiece

The factory mouthpiece often becomes a bottleneck in airflow. HSP solves this with a hand-fabricated, larger-diameter mouthpiece, designed for improved bends and flow characteristics. When paired with the Cold Air Intake, this setup ensures optimal performance and seamless airflow into the turbocharger.
