High quality product supplied as a complete kit. Installation is quite simple and straightforward with video instructions from the Mishimoto website. Note: I had to cut about 3 inches off the factory heater hose (1.5 inches from each end) to prevent the hose from bending completely in 2 places. Hose fitted perfectly after I cut it off (at Excursion 2005) Hose clamps Cheap worm gear included, do yourself a favor and get some factory spring clamps, they hold the clamp 360* and don't leak.
