When you're fabricating a custom intercooling system, every component in your build needs to pull its weight. Mishimoto DuraCore(TM) Silicone Intercooler Boots are engineered to be the strongest link in your intercooler piping kit. -- Whether you're routing charge pipes around tight engine bays or connecting mismatched tube diameters, we have the sizes and configurations to match exactly what your fabrication requires. DuraCore(TM) boots are available in straight, straight hump, transition, 45-degree, and 90-degree configurations, with sizing from 3" to 4", giving you the flexibility to complete your piping kit without compromise. Whatever your layout demands, Mishimoto has every size and shape to meet your build. -- DuraCore(TM) technology is the synthetic material comprising the innermost layer of every Mishimoto silicone boot. Compared to standard silicone, DuraCore(TM) delivers superior resistance to heat, pressure, fuel, and oil, effectively extending boot life by preventing leaks and blowouts under high-boost conditions. Each boot is manufactured from five layers of silicone with heat-resistant embedded fibers, and reinforcing rings (where applicable) add structural integrity to keep connections secure under pressure. Hump-style couplers introduce additional flexibility to absorb movement and vibration without compromising the seal. -- You've put serious work into your truck build. Don't let the boot be your failure point. With DuraCore(TM) Silicone Intercooler Boots, it never will be.

Beautiful, spacious yet compact, sturdy shelf
Color: 1. Carbonized Black, Color: 1. Carbonized Black
The only shelf I've ever bought and hung on a wall and I love this s**t. It is absolutely beautiful on the wall and you wouldn't think it could hold so much weight. Installation was fairly easy with the use of a power drill and the included wall studs. I use it to hold a few sketchbooks and journals, my PS4 games, and any other random stuff I like displaying. If I had more books I'd throw em on there no problem.

Wonderful shelf!
Wow, this is a great shelving unit and the price is wonderful. I wanted something that was modern and NOT barnboard, country feel. This is very classy and I like the metal sides and the shelves. It doesn't like cheap or flimsy! Install was easy and they provided a template too! I am very happy and impressed with this unit!

Great low cost option!!!!
Color: Natural Wood, Color: Natural Wood
I was looking for some cute storage for my bathroom. I am a skin care product junkie. I saw lots of options but when these popped up, I thought for $19.99 I’m giving it a try. They are a really nice low cost option. They were simple to put together and hang. I’m very impressed with how much they hold and how nice they look. The hardware is very durable and the color looks great!
