What size clamps do I need?

Standard hose clamp sizing for 3.50" diameter hose runs T-bolt or worm-gear clamps in the 3.5" to 4" range. Verify your existing line clamps or grab a set rated for that diameter — most common automotive suppliers stock them.

Can I use this for both coolant and boost?

Yes. Silicone construction handles both coolant loops and turbo/supercharger boost lines. Just make sure your clamps are tight and inspect for weeping at connections under load.

Does this come with end fittings?

Hose only — no fittings included. You'll use your existing barbed fittings or swap them to match your new line routing. Measure your old hose connection points before ordering.
