Improve the power and efficiency of your 2017-2019 Chevrolet/GMC 6.6L Duramax L5P with our Mishimoto intercooler pipe and boot kit. The factory L5P intercooler pipes are a measly 2.5in diameter that chokes the engine, while tight bends and a resonator on the hot side create even more restriction.The Mishimoto intercooler pipes are 3in in diameter throughout with smooth transitions to significantly increase airflow, resulting in more power potential. Our hot-side pipe also eliminates the stock resonator for maximum flow. Combined, the Mishimoto intercooler pipes are up to 55-percent less restrictive than stock.Both the hot-side and cold-side utilize a two-piece design for ease of install. To connect the pipes to our Duramax, this kit also includes our silicone boots with DuraCore(TM) technology. Mishimoto DuraCore(TM) technology is the synthetic material that comprises the innermost layer of all Mishimoto silicone diesel boots. Compared to normal silicone, DuraCore(TM) provides superior resistance to heat, pressure, fuel, and oil. This effectively increases the life of our boots by preventing leaks and blowouts.To add even more reliability, this kit includes Mishimoto constant-tension T-bolt clamps for accurate and consistent holding power. Our cold-side intercooler pipes also feature a CNC-machined quick-disconnect fitting with new O-ring and spring clip to ensure a secure and leak-free fit. Unlike other available pipes on the market, our pipes retain the intake air temp harness mounting location for safe and secure wire routing, just as Chevy/GMC intended. Our intercooler pipes also incorporate two bungs that can be drilled and tapped for sensors, so you can easily monitor your L5P's performance.The Mishimoto 2017-2019 Chevrolet/GMC 6.6L Duramax L5P intercooler pipe and boot kit is a direct bolt-on upgrade and is available in a polished or wrinkle black powder coated finish. Like all our Duramax products, this kit includes our Mishimoto Lifetime Warranty.

It’s ok
Size: X-Large, Color: Gray
This jacket is OK. I bought it for my boyfriend because I really like the coat collar but once it got here. The front fits well but I think the back needs a little more tailoring because it kind of sticks out but he really liked it. He said he could put a heavy sweater up under it. That way he can get more ware out of it. It’s OK.

NICE AND STRETCHY
Color: Navy Blue, Size: 42
These pants are made of a material that seems durable and is definitely comfortable, and they have a stretch band at the waist that can comfortably accommodate many different belly girths-- from slim to portly. The waist also has a drawstring. I'd call these light weight pants, as the material is thin. They aren't baggy at all and fit the natural contours of an average male physique. The pants have two fairly deep front pockets and one small rear pocket that can easily fit a regular-sized wallet. But, I would not recommend carrying a wallet in the rear pocket, as, due to the depth of the pocket being only as deep as the wallet is long, it might slip out as you move around, sitting and rising. If nature calls, and you need to pee, you will have to pull your pants down and excite anyone in the immediate vicinity, as there is no opening, either buttoned or zippered, in the front of the pants. So, in that respect they are kind of like sweatpants. I'd call these pants good for inside the house or wearing on the street. I like them despite the lack of a fly, so I give 5 stars. I see lots of Chinese, Korean, and Japanese guys around who like to wear this type of pant, but these fit nicely for generally larger and more robust Caucasians type physiques as well. You don't have to worry about a belt or a broken fly zipper with these. Of course they are made in China, but due to their vast experience selling clothing to Americans, the manufacturers are well acquainted with big masculine American bodies and their needs.
