2.50" 90 Degree Silicone Hose - 3-Ply Black

Do I need clamps to install this?

Yes. This hose is barb-style, so you'll need two hose clamps rated for your application pressure. Stainless or spring clamps both work; tighten until snug and check for leaks under boost.

Can I use this for coolant or just boost lines?

Either one. This silicone handles coolant loops, intercooler plumbing, and positive boost connections. Just make sure your clamps and fittings match the system pressure you're running.

What if the elbow doesn't fit my existing ports?

Measure your barb fitting diameters first — this hose is sized for 2.50" bores. If your current fittings are different, you'll need adapters or different-sized hose to make the connection work.
