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(TM) 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:

Quality Leather That Actually Protects Your Info
Color: Navy Blue
I’ve been carrying this Timberland wallet for a while now, and it’s a solid upgrade from my old one. The first thing you notice is the quality of the leather—it feels rugged and genuine, not that stiff, plasticky stuff you see on cheaper brands. It has that classic Timberland look that ages well the more you use it.
The main reason I grabbed this specific one was for the RFID-blocking technology. With so many "tap to pay" cards out there, it’s nice to have that extra layer of security knowing my info isn't being skimmed while the wallet is in my pocket. Even with the protection built-in, the wallet isn't overly bulky; it still fits comfortably in my back pocket without feeling like I’m sitting on a brick.
The passcase design is really convenient because it has a removable flap for your ID. This is perfect for when you just need to show your license quickly without digging through the whole wallet. It has plenty of slots for cards and a large enough section for cash that doesn't feel cramped. If you want a durable, good-looking wallet that keeps your data safe, this is a great choice. It’s just a good, reliable wallet that does exactly what it's supposed to do.

Timberland Men’s Genuine Leather Wallet – Nice Quality for the Price
Color: Navy Blue
This wallet was actually a gift, so I can’t really say how durable it is long term or whether it completely met expectations over time or whether it was returned. However, when I first received it, it definitely looked and felt like a quality wallet. The genuine leather had a nice appearance, the stitching looked well made, and it had a clean and classic style.
The price also seemed very reasonable for what you get. Overall, based on first impressions, it appears to be a solid wallet and would make a nice gift option for someone.

Fits my needs, and ID folio is removable
Color: Navy Blue
Just the right size, number of card and cash pockets for the way I like my wallets. Well-crafted, looks good. And, bonus points, the ID part slips right out of it, so I can use the slimmer wallet. If you want the ID part, then being abel to slide it out and present it without the wallet is probably good. I trust that the RFID blocking, a good feature, works. I have no need to test it, though.
