Intercooler Pipe for LML 2011-2016 Chevy / GMC 6.6 Duramax

Intercooler Pipe Kit For 2011–2016 GMC / Chevy 6.6L LML Duramax Diesel

Improve the boost reliability and airflow performance of your 6.6L LML Duramax with our Hot & Cold Side Intercooler Pipe Kit, engineered for 2011–2016 GMC and Chevrolet HD trucks. This premium upgrade replaces the factory plastic intercooler pipes with high-strength mandrel-bent aluminum piping and triple-reinforced silicone boots, ensuring maximum durability under high boost and extreme heat.

Stock pipes are known to weaken over time due to repeated heat cycles and boost pressure. The DPFexhaust intercooler pipe kit eliminates these weak points, delivering stronger boost containment, improved airflow efficiency, and long-term durability for towing, performance driving, or daily use.

Whether your truck is stock or tuned, this kit provides a dependable upgrade that helps keep your turbocharged diesel running smoothly under demanding conditions.
