Using this Pusher Max Passenger - Side Charge Tube is straightforward. First, gather all the included hardware, gaskets, and wire loom. Then, carefully remove the old charge tube from your 2004.5 - 2005 GM LLY 6.6L Duramax engine. Next, install the new charge tube, making sure the CNC - machined and laser - cut flanges fit perfectly. The o - ring seal at the intake bridge flange makes it easy to remove and reinstall if needed. Remember, this product is for off - road use only as it's not emissions compliant. For maintenance, regularly check the welds and the support system. If you notice any signs of damage or wear, contact the manufacturer. Keep the tube clean to ensure optimal air - flow and performance. If you have any questions during installation or use, don't hesitate to reach out to our customer service team.
