Mishimoto Hot-Side Intercooler Pipe & Boot Kit – 2017-2019 L5P Duramax

Mishimoto’s 3-inch hot-side intercooler pipe and boot kit boosts airflow up to 55% over stock for 2017-2019 Chevy/GMC 6.6L Duramax L5P trucks.

Description

The Mishimoto MMICP-DMAX-17HWBK is a wrinkle-black powder-coated hot-side intercooler pipe and boot kit purpose-built for the 2017-2019 Chevrolet and GMC 6.6L Duramax L5P. Where the factory hot-side pipe chokes down to a restrictive 2.5 inches and routes boost through tight bends and a built-in resonator, Mishimoto’s two-piece aluminum replacement runs a full 3 inches in diameter from end to end and deletes the factory resonator entirely, opening up the force induction path for real airflow gains.

This forced induction upgrade is engineered to be up to 55 percent less restrictive than the stock piping, giving the L5P’s induction system more headroom to breathe without demanding any additional tuning. Every kit pairs the mandrel-bent aluminum pipe with Mishimoto silicone boots built with DuraCore(TM) technology, a synthetic inner layer that resists heat, pressure, fuel, and oil far better than standard silicone, extending boot life and guarding against leaks and blowouts. Constant-tension T-bolt clamps back up every connection with accurate, consistent holding power, and the pipe’s bung can be drilled and tapped for additional sensors, making this a genuinely versatile performance induction upgrade for owners who want dependable, direct bolt-on gains from a trusted forced induction system builder.
