Description
The factory oil cooler hose on the 2021+ Jeep Wrangler JL Rubicon 392 is a known weak point. OEM rubber cracks and collapses at the bend under the repeated heat cycling the 6.4L V8 generates during trail use and low-speed crawling — splitting at the exact point of greatest flex. It's not a matter of if, it's when.
The Mishimoto Silicone Oil Cooler Hose eliminates the failure mode at its source. A single continuous silicone piece replaces the factory hose and plastic joiner, engineered to hold its shape through the full bend radius regardless of temperature or pressure.
Why It Works
- Smooth internal taper — eliminates the pressure pockets and flow restriction created by the OEM step-change at the plastic joiner
- Embedded fiber reinforcement — resists expansion and collapse under sustained pressure where factory rubber softens and distorts over time
- Full silicone construction — rated for the sustained heat cycling the 392 V8 produces; holds its shape and seal where rubber fails
- Worm-gear clamps included — secure, field-serviceable connection at each end
