Improve the power and efficiency of your 2017-2019 Chevrolet/GMC 6.6L Duramax L5P with the Mishimoto cold-side intercooler pipe and boot kit. The factory cold-side pipe for the L5P is a measly 2.5in that chokes the engine and tight bends create even more restriction. The Mishimoto cold-side intercooler pipe is 3in in diameter throughout with smooth transitions to significantly increase airflow, resulting in more power potential. Mishimoto designed this pipe as two pieces, like the factory pipe, for ease of install. This kit also includes our silicone boots with DuraCoreâ„¢ technology. Mishimoto DuraCoreâ„¢ technology is the synthetic material that comprises the innermost layer of all Mishimoto silicone diesel boots. Compared to normal silicone, DuraCoreâ„¢ 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 cold-side 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.The Mishimoto 2017-2019 Chevrolet/GMC 6.6L Duramax L5P cold-side 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 cold-side intercooler pipe and boot kit includes our Mishimoto Lifetime Warranty for a lifetime of performance.Shipping Notes

Great value dress shoes with nice detailing
Size: 11, Color: Black, Size: 11, Color: Black
I bought these black dress shoes for an occasional formal wear, and overall I’m quite pleased with them for the price.
Fit & Comfort: The size is accurate (true to size for me). They fit well right out of the box with no major break-in period needed. The pointed toe is a bit more tapered/narrow than I usually prefer, but it’s stylish and not uncomfortably tight. The main downside is the thin padding/insoles — they’re a little firm underfoot. However, this is an easy fix; I’ve already swapped them for better aftermarket insoles and the comfort improved significantly.
Quality & Appearance: The quality is solid for the money. The faux leather has a nice shine, and the crocodile-embossed pattern on the toe cap and sides looks sharp and premium in person (see my photos). Stitching is clean, the sole has decent tread for a dress shoe, and they feel sturdy. No loose threads or cheap-feeling construction. They’ve held up well so far after several wears.
Value: Excellent bang for the buck. They look much more expensive than they cost and are a solid choice if you’re looking for stylish dress shoes without spending a fortune.
Would recommend, especially if you plan to add your own insoles. Perfect for office, weddings, or events where you want to look polished.
