One brand new 35ft of Mishimoto extreme heat wrap still in sealed bag . One 25 ft of Mishimoto extreme heat wrap that was opened and 10' was cut off . Works great on my 2000 f250 7.3 turbo diesel . Brought down my EGTs (exhaust gas temperature) 100% and helped with spool up minimally . The main reason to use Mishimoto is there quality and durability . Comes with 10 steel heat clamps
