Description: This Intercooler Bundle Kit is a must - have for 2004.5 - 2005 Chevrolet/GMC trucks with LLY, 6.6L Duramax engines. Whether you want to boost performance, replace old stock parts, or add a splash of color to your engine bay, this bundle is your solution. Don't ignore the hot side tube in the HSP kit. Factory hotside pipes on LLY trucks often fail due to rubbing against the power steering line, causing boost leaks and power loss. HSP Diesel's direct routing to the intercooler results in cooler temperatures, better airflow, and more engine bay space. Their 3' mandrel - bent tube can be powder coated for a stylish look. The 3' cold side pipe, made from a mandrel - bent tube, ensures smooth air flow and connects to the factory - style bridge for top - notch performance. Part Number: HSP - D - 292 - HSP. Features include pressure testing to 100 PSI, 3' mandrel - bent tubes, compatibility with factory emissions, power and airflow increase, multiple powder coat options, and suitability for stock applications. It includes (1) 3' mandrel - bent hot side tube, (1) 3' mandrel - bent cold side tube, (1) 3'x4' Straight Boot, (4) 3' T - Bolt Clamp, (2) 2.25' T - Bolt Clamp, and (1) 2.25' to 3' Reducer Boot. Notes: For LLY 04.5 - 05 VIN Code 2, the engine code is the 8th character of the VIN, and the 10th is the truck's year. This kit is ideal for factory or drop - in replacement chargers as it mimics factory intercooler routing.

Using this intercooler bundle kit is quite straightforward. First, make sure your vehicle is a 2004.5 - 2005 Chevrolet/GMC with an LLY, 6.6L Duramax engine. Check the VIN number to confirm the engine code (the 8th character) and the year (the 10th character). If you have an LLY 04.5 - 05, it should be VIN Code 2. Start by removing the old intercooler parts carefully. Then, install the new 3' mandrel - bent hot side tube and the 3' mandrel - bent cold side tube. Use the provided T - bolt clamps to secure the tubes properly. Connect the cold side pipe to the factory - style bridge. The straight boot and reducer boot also need to be installed as per the included parts list. When it comes to maintenance, keep an eye on the powder - coated parts. If you notice any chips or scratches, you might want to touch up the coating to prevent rust. Also, regularly check the clamps to make sure they are tight and there are no signs of boost leaks. This kit is designed to work with factory emissions, so you don't have to worry about any major changes in your vehicle's setup. Just enjoy the increased power and better airflow it provides.
