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

Hose clamps are not included. You'll need stainless steel clamps sized for 2.50" hose—typically T-bolt or worm-drive clamps in the 2.5–3" range. Tighten snugly but don't over-torque silicone.

Can I use this for both coolant and boost lines?

Yes. Three-ply silicone handles both coolant flow and turbo boost pressure. Just verify your system's maximum operating temperature stays within silicone's rated range and use appropriate clamps at both ends.

What about elbow fittings—are they sold separately?

This is a straight tube only. 90° and 45° elbows in the same 2.50" diameter are sold separately. Straight sections pair easily with elbows to build custom routing paths.
