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

Overall ok
Size: Small, Color: Light Gray, Size: Small, Color: Light Gray
I purchased this for my son for homecoming. 6’, 170, size S. The pants fit well, the jacket is kind of boxy. If you’re looking for a more slim fit on jacket, this is not it. It was too late for us to get anything else. Overall, it was fine. The sleeves At wrist not as crisp. I had to really press to give crisp shape. I steamed the heck out of it. My son was OK with it. Holds up well for one time use. Color was what we wanted.

Best bang for your buck
Size: Large, Color: Navy Blue
Highly recommend this suit if you’re looking for the best bang for your buck! We did go with another option, but upon receiving the suit, I will definitely keep this seller in mind for other occasions! Do wish you could mis-match the pants and blazer sizes, but still a great option if you can fit the top and bottom together! Even adjusting bigger sizes with a tailor, still cheaper than most options while not appearing as cheap as it is! Also ordered the champagne color, very admirable as well!

Great vest
Size: 12, Color: Black
Great vest. I love the slim fit. It looks very nice on my son, not baggy or boxy looking like some vest. My son has used it for several occasions including a wake, a Beta Club induction, awards day, and soon his graduation celebration at church. The quality and material are good. Definitely worth what I paid.
