Frequently Asked Questions

Do I need hose clamps to install this?

Yes. This hose requires clamps at both ends to secure it to your fittings or barbed connectors. Standard worm-gear or t-bolt clamps work — size depends on your fitting diameter, not the hose.

Can I use this for coolant and boost lines on the same car?

Absolutely. Three-ply silicone handles both coolant and pressurized intake charge without degradation. Make sure any fittings you use are rated for your intended application temperature.

What if I need a different length or a bend?

This ships as a straight section. You can cut it to length with a sharp knife or hose cutter, but bending requires a mandrel or spring — doing it by hand often kinks the hose and compromises flow. Plan your routing before install.
