Do I need hose clamps to install this?

Yes — you'll need clamps at both the 2.50" and 2.75" ends. The hose itself is the fitting; clamps secure it to your hard lines or other hose barbs.

Can this handle coolant and intercooler water lines?

Silicone handles both. It's stable in high-temp coolant systems and rated for intercooler duty. Just verify your system pressure stays within silicone's rated limits before final assembly.

Will this fit if I need the 2.75" end first and 2.50" second?

The hose is designed as 2.50" to 2.75". If you need the reverse orientation, test-fit first or contact us with your line diagram to confirm the bend direction works for your layout.
