Frequently Asked Questions
Do I need clamps and fittings to use this hose?
Yes. This is the hose section only. You'll need to source clamps rated for 4.00" diameter and appropriate fittings or barb adapters for your application — intercooler pipes, radiator overflow, or turbo inlet.
Can this handle boost pressure on a turbo or supercharger setup?
Three-ply silicone is designed for moderate pressure applications. Test-fit your setup under load before full deployment — pressure rating depends on clamp quality and fitting design, not the hose alone.
Does this need prep or coating before installation?
No prep required. Wipe clean and dry before inserting into fittings or barbs. The black exterior is ready to install as-is.
