2.25" to 2.50" 90 Degree Silicone Reducer Hose 3-Ply Black/Red

What clamps do I need for this hose?

You'll need hose clamps sized for 2.25" and 2.50" diameters—typically 2.25" and 2.5" worm clamps or band clamps. Clamps are sold separately.

Can I use this for both boost and coolant lines?

Silicone handles both applications. Test your system pressure against your hose rating before installation—consult your turbo or intercooler spec sheet if running boost.

Will this hose fit tight at the connection points, or will it slip?

The stepped design sits loose until clamped—proper clamp tension is critical. Tighten firmly but don't over-torque; a clamp that's too tight can pinch the silicone and weaken the seal over time.
