20 Best Cold Air Intake For Duramax Lly (2022 Updated)

A cold air intake is an aftermarket assembly of parts used to bring cooler air into a vehicle’s internal combustion engine. The main purpose of a cold air intake is to improve the performance and efficiency of the engine by increasing the amount of oxygen-rich air that it can take in.

More oxygen in the air/fuel mixture results in a more complete burn of the fuel, which in turn produces more power and better fuel economy.
