Mishimoto 3in-3.5in Transition Boot

Mishimoto is proud to release a 3.0" to 3.5" transition silicone boot with DuraCore™ technology. Mishimoto DuraCore™ technology is the synthetic material that comprises the innermost layer of all Mishimoto silicone boots. Compared to normal silicone, DuraCore™ provides superior resistance to heat, pressure, fuel, and oil. This effectively increases the life of our boots by preventing leaks and blowouts.
