The Mishimoto Silicone Oil Cooler Hose replaces the factory rubber oil cooler hose on the Jeep Wrangler 392, which cracks and collapses at the bend under the repeated heat cycling of the 6.4L V8. It is a single continuous silicone piece with embedded fiber reinforcement that holds its shape and resists expansion and collapse under sustained pressure. A smooth internal taper runs the full length to remove the flow restriction created by the factory plastic joiner, and worm-gear clamps are included for a secure, field-serviceable connection at each end.
