Frequently Asked Questions
Will this hose need clamps, and what size should I use?
Yes, you'll need hose clamps to secure both ends. Since this is a 4-inch diameter hose, use T-bolt or worm-drive clamps rated for that size. The exact clamp size depends on the ID of your barbed fitting or adapter.
Can I use this on a turbo intake or only for coolant?
This hose is rated for boost, coolant, and vacuum applications. If you're running it on a turbo intake, confirm your boost level stays within the hose's pressure rating—silicone typically handles 15–20 psi reliably, but check the specs for your specific turbo setup.
Do I need to do anything to prep the hose before installation?
Inspect the interior and exterior for defects before cutting or fitting. If you're trimming the length, use a sharp utility knife or hose cutter to avoid fraying the edges. Soak the hose ends briefly in warm water if they're tight over fittings—silicone softens slightly when warmed.
