EMUSA 4" To 4" Straight Silicone Hose - 102mm Blue 4-Ply Turbo/Intake Coupler

Building a custom intake or intercooler setup?

This EMUSA straight silicone hose is just what you need.

It's a 4-inch to 4-inch coupler, so it's perfect for joining two pipes of the same size.

The inside diameter is a true 102mm.

This thing is built tough—it's a 4-ply silicone construction with a thickness of 4.5mm, so it can handle the pressure and heat of a turbo setup without collapsing.

The bright blue color looks great in any engine bay too.

It comes with a 90-day warranty, so you know it's solid.

Whether you're piecing together a custom intake, charge pipes, or just need a high-quality replacement for a worn-out coupler, this EMUSA hose will get the job done.

One hose per pack.

Add some color and reliability to your build!
