Do I need hose clamps, and what size should I use?

Hose clamps are not included with this reducer. You'll need standard worm-drive or band clamps sized to fit your 2.25" and 2.50" connections — most builders use 2.0" to 2.5" range clamps on each end. Match the clamp size to the hose diameter at that point.

Can this handle boost pressure on a turbo or supercharger setup?

Yes — the 3-ply reinforcement is designed to manage positive pressure on intake and boost lines. For extreme boost applications, confirm your system's PSI rating and clamp securely at both ends to prevent any movement under load.

Should I clean or prep the hose before connecting it?

Wipe the inside surfaces with a clean, dry cloth to remove any manufacturing dust or debris before sliding onto fittings or barbed connections. No special prep required — silicone installs ready to go.
