What size clamps do I need for this hose?

Hose clamps for a 3.00" diameter line typically run between 2.75" and 3.25" clamping range — grab a standard worm-drive clamp in that window. Tighten snug enough to seat the hose without over-torquing the barb.

Can I use this on a turbocharged application?

Yes. Three-ply silicone handles boost pressure and heat cycling. Just match it to your system's PSI rating and verify the 45-degree angle works with your boost line routing before committing.

Does this need to be primed or painted before installation?

No prep needed. Install it as-is. Black silicone won't degrade under the hood and requires no primer or coating.
