Frequently Asked Questions
Will this hose work for both coolant and boost lines?
Yes. The 3-ply silicone handles both coolant system heat and turbo/supercharger boost pressure. Just verify your line diameter matches the 2.50" specification before ordering.
Do I need hose clamps, or are they included?
Clamps are not included with this hose. You'll need two stainless-steel hose clamps rated for your pressure range — most builders use T-bolt or worm-drive clamps sized for 2.50" diameter.
Can I cut this hose or modify the length?
The 90-degree elbow is molded and cannot be shortened or cut without losing the bend. Measure your routing path before ordering to confirm this angle works for your layout.
