Benefits & Tips

• Durable upgrade: Silicone hoses handle higher engine temperatures and resist hardening, reducing the risk of oil soaking and vacuum leaks compared with original rubber hoses.
• Oil-leak prevention: A reliable PCV hose kit helps maintain proper crankcase ventilation, minimizing oil seepage into the intake and reducing buildup over time.
• Easy install with included tools: Replaces the old hose quickly using the 7-piece Disassembly tool kit, plus the provided fitting and wrench for a secure, leak-free connection.
