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.

Does not connect
First the hoses do not connect together causing all kinds of vacuum leaks. There is no rifling in the diaphragm so oil leaks back up. Cheap piece of plastic

Amazon size charts need help
Size: Small, Color: Dark Denim
The dress is sharp. Well made. The Amazon size guide and AI size helper not so great. It was suggested to me to order a size large. Well I knew that was wrong so I went with the medium due to size chart. Still way too big. Had to return the medium and order a small . That also was too big and now had to order an XS . What a hassle. Please correct the size chart. Would very much appreciate the accessories listed that the model is wearing such as who’s boots she is wearing
