❄️ HSP Cold Air Intake – 2013–2016 Duramax LML (Part #502-2-HSP)

Breathe Power Into Your LML. Boost performance, lower temps, and clean up your engine bay — all in one bolt-on upgrade.

If you're running a 2013–2016 Chevy or GMC Duramax LML, this is the cold air intake your truck deserves. The HSP 502-2-HSP Cold Air Intake is dyno-proven to add +20 HP and +58 lb-ft of torque, while improving spool-up and overall throttle response.


Why Choose HSP?

🔥 Built for Performance
Replaces the restrictive factory intake with a 4.5” mandrel-bent tube for smooth, unrestricted airflow. Pair that with a performance filter and a heat-deflecting airbox, and you’ve got colder, denser air feeding your turbo = more power.

📈 Dyno-Tested Gains
+20HP / +58TQ on stock VGT turbos with better throttle response and spool-up.

🛡️ Engine Bay Heat Blocked
HSP’s signature air-tight heat shield box ensures only cold, dense air hits your intake — keeping IATs low and power high.

🎨 Clean Look, Custom Options
Choose from a wide variety of powder coat colors to match your build and elevate your engine bay.

🧩 Direct Fit for 2013–2016 Duramax LML
Fits all LML 6.6L engines with VIN Code 8 (check the 8th digit of your VIN).
