The TiAL Sport 3.25in to 4.00in silicone reducer is a 3-inch coupler built with 4-ply poly reinforcement and a glossy blue finish. It transitions between 3.25 and 4.00 inch inner diameters for intake or intercooler plumbing, providing a compact, reinforced connection where a brief step-up or step-down is needed while preserving hose routing neatness.
