Do I need hose clamps to install this?

Yes. Clamps are not included with this hose. You'll need appropriately sized clamps for both the 2.75" and 3.00" ends — worm-gear or T-bolt clamps work well depending on your plumbing setup.

Can this hose handle boost pressure?

The 3-ply construction is rated for pressurized systems. Exact pressure rating depends on clamp torque and installation method — verify your boost level against hose specifications before final assembly.

Will the red inner lining affect coolant or other fluids?

The red lining is dye in the silicone, not a separate coating. It's compatible with standard coolants, water, and boost piping applications — rinse before first use if flowing coolant.
