Description

The K&N AirCharger Intake System 57-3047 from XDP is designed to increase the power in your 2004.5-2005 GM 6.6L Duramax LLY. A high-density polyethylene (HDPE) rotationally-molded tube helps increase the volume of airflow to your engine and provides a guaranteed increase in horsepower and torque. This cold air kit is paired with a washable, reusable High-Flow Air Filter featuring oiled cotton filter media. The oversized, conical design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. A custom heat shield helps protect intake air from the high temperature of your engine bay, and the entire system can typically be installed in less than 90 minutes.

  • Guaranteed To Increase Horsepower And Torque
  • Engineered To Provide High Airflow And Exceptional Filtration

Installation Tech Tip:
The Mass Air Flow (MAF) Sensor is mounted in the intake tube of the air intake system. During installation of a cold air intake, the MAF must be removed and moved over. While replacement of a functioning MAF sensor is not necessary, it is considered a good practice to inspect, clean, or replace the sensor (if needed) whenever it's removed.

Great
05LLY (Usa) | April 23rd, 2023
Great fit but lots of hot air comes in from the fan around the tube hole. Also the box came with instructions for a 2011 duramax. So I had to go online and get The correct ones. But other than that work great install was easy.
