DuraCore™ Technology:

DuraCore™ is the proprietary synthetic material that forms the innermost layer of every Mishimoto silicone boot. Compared to standard silicone, DuraCore™ provides significantly superior resistance to heat, pressure, fuel, and oil — extending boot service life by preventing leaks and blowouts under demanding conditions.

• Multi-layer silicone construction with heat-resistant embedded reinforcing fibers for maximum durability
• Rated for temperatures up to 330°F and built to handle substantial boost pressures
• Available in black (BK suffix) finish for a clean, stealth appearance
