Silicone 90 Degree Turbo Coupler For 4 Inch Intake Pipe, Black

Route boost air smoothly around tight bends with this black silicone coupler. Built specifically for 4-inch intake piping, the 90-degree elbow directs airflow between your turbo outlet and intercooler lines. This setup prevents vacuum collapse and keeps cylinder filling high during heavy throttle applications.

The flexible wall material absorbs engine vibration while holding a firm grip on your existing tubes. You get a direct replacement that fits cleanly into most front-mounted turbo routing jobs without cutting extra angles.

Benefits & Practical Tips

• Extreme Temperature Handling: Resists degradation across a working range from minus forty to plus five hundred degrees Fahrenheit.
• Smooth Assembly Tip: Lightly coat mating pipe ends with a rubber-safe lubricant before sliding the coupler on to protect the internal bore.
• Secure Fit Advantage: The three-ply layered silicone dampens harsh road shock, helping your clamps resist loosening over long drive cycles.
