Upgrade your turbocharger piping intercooler connections or high boost air intake with this Vibrant Performance transition coupler connecting 3.5-inch to 4.5-inch pipes. Hand-wrapped 4-ply aramid reinforced silicone handles extreme pressures without swelling or bursting in custom setups across drag racing street performance and motorsports builds. Rated from -65°F to 350°F it meets SAE J20 standards for reliable boost retention.
Key Features
- 4-Ply Aramid Reinforcement: Withstands heavy duty boost pressures up to 100 psi and prevents collapse under vacuum for consistent airflow
- Wide Temperature Range: Operates from -65°F to 350°F resisting heat soak cold starts and track abuse
- SAE J20 Compliant: Exceeds industry standards for coolant compatible hoses ensuring vibration resistance and longevity
- UV and Ozone Resistant: Maintains flexibility and shape in outdoor engine bays exposed to weather and chemicals
- Precise Transition Design: Smooth 3-inch length taper from 3.5in ID to 4.5in ID eliminates turbulence in intercooler piping and intake tracts
