Mishimoto Silicone 90Deg Reducer Coupler 3in to 4in Black

Silicone 90-degree reducer coupler that transitions 3in to 4in while providing reliable connectivity for coolant and air passage systems from Mishimoto, delivering a dependable join for routing changes and system layouts.

This Mishimoto Silicone 90Deg Reducer Coupler 3in to 4in Black is designed as part of Mishimoto’s expansive silicone coupler lineup, intended for use where a compact 90-degree transition is required between different diameter hoses in cooling or intake/air systems.

• 90-degree transition — Enables tight routing around engine bay obstacles; useful where a straight coupler cannot be installed without stress or sharp bends.
• 3in to 4in reducer — Provides a stepped diameter transition for joining dissimilar hose sizes, simplifying integration between a 3-inch and 4-inch circuit.
• Compatible with coolant and air passage systems — Suitable for both coolant plumbing and air routing applications, allowing a single part to serve multiple system needs.
• Black finish — Neutral appearance that integrates with standard engine bay components and aftermarket plumbing layouts.
• Part of Mishimoto’s silicone coupler range — Backed by Mishimoto’s focus on engineered silicone solutions for performance and reliability.

Key functional benefits: this reducer coupler simplifies plumbing design when changing diameters at a 90-degree angle, reduces the need for multiple fittings, and supports cleaner routing of coolant or air lines in constrained spaces.
