Construction & Design

This silicone coupler is built with a multi-layer design that enhances its strength and flexibility. The 5-layer construction includes a high-grade silicone exterior reinforced with embedded fibers, ensuring it can handle the stresses of high boost pressures and temperature fluctuations. Its straight, 4-inch diameter design allows for easy installation and compatibility with a variety of piping sizes. The smooth inner surface promotes unrestricted airflow, reducing turbulence and maintaining consistent intake performance.

The black finish not only provides an attractive appearance but also adds an extra layer of protection against UV rays and environmental wear. The coupler's precise manufacturing process ensures a uniform wall thickness and a perfect fit, minimizing the risk of leaks or blow-offs during spirited driving or racing conditions.

Performance & Sound

While this coupler is primarily a functional upgrade, its high-quality silicone material helps improve airflow compared to standard rubber or lower-grade hoses. This can contribute to more responsive throttle behavior and support the overall performance of your forced induction system. Its ability to withstand high boost pressures ensures reliable operation under demanding conditions, making it a dependable component for performance enthusiasts.

Installation & Fitment

The Torque Solution 4" straight silicone coupler is designed for easy, bolt-on installation. It fits directly onto 4-inch diameter piping and is compatible with a wide range of vehicles and applications.
