Description
The Mishimoto MMICP-DMAX-17KWBK intercooler pipe and boot kit replaces the restrictive factory piping on the 2017-2019 Chevrolet/GMC 6.6L Duramax L5P with a direct bolt-on, 3-inch aluminum pipe system that eliminates the stock hot-side resonator and its tight bends entirely. Where the factory L5P pipes measure a choked 2.5 inches in diameter, this Mishimoto forced induction upgrade opens the entire path to 3 inches with smooth, mandrel-bent transitions.
Built for shops and DIYers looking to unlock more airflow from their induction system without sacrificing reliability, this kit combines aluminum pipes with Mishimoto silicone boots featuring DuraCore technology for superior resistance to heat, pressure, fuel, and oil versus standard silicone. Constant-tension T-bolt clamps deliver accurate, consistent holding power at every connection, while a CNC-machined quick-disconnect fitting on the cold-side pipe with a new O-ring and spring clip ensures a secure, leak-free fit. Combined, the Mishimoto forced induction pipe kit is up to 55-percent less restrictive than the factory setup, giving your L5P’s induction system real room to breathe without requiring additional tuning.
