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.This Part Fits:

Cutting boards will splinter
A lot of the reviews that are saying these wooden boards splinter are true. I was excited to find some nontoxic wooden cutting boards for such a great price. Upon arrival, they seemed pretty decent quality when I pulled them out of the package. I proceeded to use the large one so I gave it a quick rinse with warm water and was taken back by fumes coming off the cutting board and then wiped it down with a white paper towel and my paper towel was brown. I was a little discouraged, but decided to give it a better rinse with a soap, free brush. At that point once I dried it off whatever coding was on it came off and it was rough and splinters everywhere. Definitely a little upset that the splinters could’ve ended up in our food. These are not good quality non-toxic cutting boards I would rather spend a little extra money on a quality board that is not going to sprinter Wood shavings into my food.

Very good, just be sure not to leave in water
Overall, this is a very good product as my wife and I are moving towards non-toxic kitchen materials. My only advice is to make sure to not leave this submerged in water otherwise mold will easily form.

Truly non-toxic but a little rough and uneven
I’m very impressed with the packaging of this. When I first opened the box I was shocked that there was a plastic wrapping around the boards when they promised to be non toxic but then I saw the sticker that the wrapping was not plastic and I was very happy. The boards themselves are pretty nice and a good thickness but the only thing is I feel like the board is a little rough and parts of the board come up and are not smooth.

Not Durable…Splintered….
Had to chuck these. I loved them at first but they are not durable. Scratched themselves up right away and then the mid sized one started to splinter. I didn’t even have it for very long before I had to get rid of them. Long enough to not be able to return. I prefer the bamboo as far as wood goes, but switched to an antibacterial. It’s crazy because I had the same cutting boards for years and in the past month I’ve had to replace them 3 times now. I was so disappointed because there were such amazing reviews. Sadly that was not the case for me. I give it a 3 because they are absolutely beautiful…..you get points for being beautiful I suppose in this world. But not durable. At least not for me.
