HPS Performance Products 2.75 to 3.75 Inch Blue 4-Ply Silicone Reducer Coupler Hose
$52.45

If you're diving into some serious performance upgrades or just need a reliable silicone hose for your project, the HPS 2-3/4" to 3-3/4" (70mm - 95mm) 4-ply Reinforced Blue Silicone Reducer Coupler Hose is a solid pick. This isn't just any hose; it’s built to handle the heat—literally. With a max temperature rating of 350°F (177°C), it can take the heat without breaking a sweat.

This hose measures 3 inches in length and features a 4-ply design, which means it’s tough enough for heavy-duty pressure connections. Whether you're working on custom turbo setups, intercooler piping, or even DIY intake systems, this hose has you covered. Just a heads up, it’s not compatible with fuel or oil, so keep that in mind when planning your setup.

What I really like about this hose is its UV and ozone resistance. If you’re using it in a marine environment or somewhere it might see some harsh conditions, that’s a big plus. Plus, the blue color? It looks sharp in any engine bay.

  • Type: Silicone Reducer Coupler Hose
  • Color: Blue
  • Inside Diameter: 2.75" - 3.75" (70mm - 95mm)
