Epartsgogo 4 Inch Straight Silicone Coupler - 3-Ply JDM Turbo Hose For Air Intake (Black/Red)

Building a custom intake or intercooler setup?

This Epartsgogo silicone coupler is what you need.

It's a brand-new, 4-inch inner diameter (ID) straight coupler, made from tough 3-ply silicone.

It comes in a classic black with red accents—a nice touch for any engine bay.

This is a performance part, so please note it's a universal fitment, meaning it's NOT a direct bolt-on for any specific car.

You will likely need additional modifications and piping to make it work.

Professional installation is highly recommended.

But if you're fabricating a custom setup for a turbo, supercharger, or intercooler project, this high-quality coupler from Epartsgogo (MPN: CPL-164BR-878-O3) is a great choice for joining your 4-inch pipes.
