Hot Side Intercooler Pipe Kit

Upgrade your Duramax engine's performance and durability with the SPELAB Hot Side Intercooler Pipe Kit. This kit is specifically engineered for 2004.5–2010 GM 6.6L LLY, LBZ, and LMM diesel engines, offering a robust alternative to the stock plastic pipe that is susceptible to failure under high boost and heat. The intercooler pipe is constructed from mandrel-bent 6061 aluminum, which provides improved airflow and superior resistance to deformation and cracking compared to the OEM component. This direct bolt-on design integrates seamlessly with factory intercooler and turbo components, utilizing existing mounting points for a straightforward installation process that requires no cutting or additional tuning. The package contains one hot side intercooler pipe, two silicone boots, and four T-bolt clamps. This upgrade is ideal for owners looking to replace a cracked or aging factory hot side pipe, as well as for those with tuned or heavy-duty Duramax applications that demand reinforced charge-air plumbing. The SPELAB Hot Side Intercooler Pipe Kit is compatible with the 2004.5-2005 6.6L LLY Duramax Diesel, the 2006-2007 6.6L LBZ Duramax Diesel (VIN Code 2 or D), and the 2007.5-2010 6.6L LMM Duramax Diesel (VIN Code 6). Installation is estimated to take 1–2 hours with basic hand tools.
