Description

Mishimoto MMINT-DMAX-17KSLP Performance Intercooler Kit, fits Chevrolet/GMC 6.6L Duramax L5P 2017-2019Built 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.

DIDN'T LAST LONG
Color: 5885 Gold Stainless Steel/Gold Dial
Bought this in June 2025, and only wore it a few times. Recently noticed the time was "off" and the seconds-hand wasn't moving. I thought it sat too long and needed to be wound up. So, I wound...and wound...and wound. Never met any resistance in the crown during clock-wise winding...just continued to spin freely, and the seconds-hand never moved. It's a pretty-looking time piece, but don't waste your money if you expect it to keep time. 👎

Great watch, terrible resizing tool.
Color: 2926 Silver Stainless Steel/Black Dial
Watch is great, feel heavy, looks beautiful in person. It shines pretty heavily. My main issue is with the resizing tool it comes with. It broke when I tried to use it. Be prepared to buy your own like I did. I can’t say how the fit is yet because I can’t wear it yet. It is not easy to set up.

Stunning Automatic Watch With TopTier Durability and Precision
Color: Grey
“I got this Tissot PRX for my cousin’s birthday and bro fell in LOVE instantly. This thing keeps time like a beast, never slows down, never lags. Automatic movement, so no batteries, no drama. Durability? Stupid good. You can hit it, bump it, live life rough, it still looks box fresh. Size wise it was almost perfect. I just had to remove two links, nothing big. It’s light, functional, comfortable, doesn’t weigh you down, doesn’t get in the way but more importantly I can say this watch is in everyone’s eyesight when we wear it. Cause of course I had to get another one! Basically. I gave him a very nice piece as a gift, and now he’s walking around like he owns Switzerland.
