HSP Diesel Cold Air Intake – 2017-2019 L5P Duramax

Feed Your L5P the Air It Deserves

The HSP Diesel Cold Air Intake is engineered specifically for the 2017–2019 Chevrolet/GMC L5P Duramax 6.6L, delivering a massive improvement in airflow over the restrictive factory airbox. Whether you're towing heavy or chasing power on the dyno, this intake gives your engine the cold, dense air it needs to perform at its peak.

Why Upgrade to the HSP Cold Air Intake?

• Increased Airflow: Dramatically outflows the stock intake, reducing restriction and improving throttle response
• Cooler Intake Temps: Sealed cold air design pulls air away from engine heat for denser, oxygen-rich charge
• High-Flow Filtration: Premium dry or oiled filter media captures contaminants without choking airflow
• Bolt-On Installation: Direct OEM fitment — no cutting, drilling, or fabrication required
• Durable Construction: Built from heavy-duty materials designed to handle the demands of diesel performance
• Dyno-Proven Gains: Real horsepower and torque improvements, especially when paired with a tune

Compatibility
