Mishimoto 17-19 GM L5P Duramax Intercooler Kit - Silver w/ Polished PipesBuilt to handle heavy payloads, provide impressive performance, and execute years of reliable service, the 2017 2019 6. 6L Duramax L5P is an absolute workhorse. However, as with any factory vehicle, some systems have limitations and areas that can be improved. Our engineering team has specifically identified the L5P's intercooler system as one of these areas. As a result, we've developed a performance intercooler kit for the 2017 2019 Chevrolet GMC 6.

Built to handle heavy payloads, provide impressive performance, and execute years of reliable service, the 2017-2019 6.6L Duramax L5P is an absolute workhorse. However, as with any factory vehicle, some systems have limitations and areas that can be improved. Our engineering team has specifically identified the L5P's intercooler system as one of these areas. As a result, we've developed a performance intercooler kit for the 2017-2019 Chevrolet/GMC 6.6L Duramax L5P.This kit includes a massive 68mm-thick bar-and-plate intercooler with cast-aluminum end tanks and 3.0in mandrel-bent piping for maximum cooling and flow. Our intercooler is 70-percent thicker than stock and is designed to be a robust unit capable of withstanding high temperatures and boost pressures without cracking. In addition, our end tanks also feature larger inlets and outlets for even more flow. That, coupled with the larger intercooler core, reduces restriction by over 64-percent compared to the stock intercooler.Our kit also includes hot-side and cold-side intercooler piping with DuraCore™ boots and constant-tension T-bolt clamps. Our 3.0in mandrel-bent aluminum piping eliminates the restrictive stock resonator and improves flow by up to 55-percent over stock. The Mishimoto L5P Duramax intercooler pipes fit like stock thanks to the included CNC-machined quick-disconnect fitting with new O-rings and spring clip, bead-rolled pipe ends, and mounting locations for factory sensors and harnesses. Our pipes also include three bungs that can be drilled and tapped for sensors or water/meth injection.The Mishimoto 6.6L Duramax L5P Performance Intercooler Kit is a direct fit for your 2017-2019 Chevrolet or GMC HD truck and is a fantastic upgrade for both stock and heavily modified trucks. Like all our Duramax performance parts, this L5P intercooler kit is protected by our signature Mishimoto Lifetime Warranty.

It works!
Fitment was great on my 2014 Subaru Crosstrek. Construction was solid and great that I don’t have to worry about changing it for 18,000 miles. Would purchase again.
