Frequently Asked Questions
Do I need hose clamps?
Yes. Clamps are not included. Standard stainless steel T-bolt or worm-style clamps work with this hose — grab your preferred size based on your connection point diameter.
Can I install this on a cold engine or do I need to wait?
Install on a cold engine. Never force a silicone hose onto a warm connection — wait for the engine to cool completely to avoid tearing the material at the fitting points.
Will this work for both coolant and boost lines?
Yes. The 3-ply construction handles coolant system pressures and turbo boost applications. Confirm your specific pressure rating against the hose specs before running it on high-boost setups.
