Mishimoto 17-19 GM L5P Duramax Intercooler Kit - Black w/ WBK 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 DuraCoreâ„¢ 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.Shipping Notes

Doesn't last long
Size: King (Pack of 1), Size: King (Pack of 1)
I have only had this pillow for 8 month and it is flat and not comfortable anymore. I sent the company an email and they never responded. I do now recommend that you buy this pillow.

The pillows have a chemical smell
Size: King (Pack of 1)
I bought two Marlow pillows a while ago. They are great pillows. The two new Marlow pillows I just purchased have a chemical odor. The manufacture date is Sept. 2024. I have them airing out hoping the smell will dissipate , so far that has not happened.

Simply The Best
Size: King (Pack of 1)
It appears there are more than 1,000 pillows advertised and available all over the Internet. The situation is a comedy routine. If you want a cooling pillow because you're a hot sleeper or if you want a plush pillow for back problems or a combination or neither, it doesn't matter. Be prepared to read 1,000 different advertisements until you start laughing out loud. This is what I did, but I wandered upon this Marlow Pillow system and then trusted the Amazon ratings. And boy am I happy, though a word of caution: if you want the cooling technology to really work you've got to pair this pillow with the Marlow pillow protector. Because Amazon didn't carry the pillow protector I bought it directly from Marlow. And this is the last pillow I'll ever get or need to get. Comfortable like a goose down pillow and yet cool to the touch and cool all night long. So I got lucky; have avoided having to buy multiple pillows; and now am enjoying the heck out of my Marlow King with the Marlow pillow protector. Lastly, this pillow is adjustable with a zipper and it works: you can make it softer or harder with a quick zip. The best pillow out there, by far!

Really good pillow!
Size: King (Pack of 1)
This is the first pillow that I have owned in the last 10 years in which I have not experienced any neck pain. It's the right density, comfort level, and is a high-quality item. I am a side and stomach sleeper. Try this pillow and I think you'll be happy.
