Do I need clamps for this hose?

Yes. You'll need two hose clamps—one for each end. This hose is the adapter; the clamps are how you secure it to your lines. Bring the diameter of each end when you order your clamps.

Can I use this on a pressurized coolant system?

3-ply silicone handles standard cooling system pressure. If you're running a high-boost setup or extreme pressure, verify your system's PSI limits against your hose supplier's specs first.

Will this work with my existing intake tubing?

This hose bridges connections where one line is 2.00" and the other is 2.25". Measure both your existing ports before ordering—if your diameters don't match those specs, you'll need a different reducer.
