Frequently Asked Questions
Do I need clamps, and what size should I use?
Clamps are not included. You'll need band clamps or worm-drive clamps sized for 3.50" hose diameter — check your hose fitting specs to confirm the exact clamp size needed for your application.
Can I use this for both coolant and boost lines?
Silicone hose handles both applications, but always verify your specific system's temperature and pressure ratings against the hose specs before final installation. Different boost systems have different demands.
Does the red color fade or require a clear coat?
The hose arrives finished in red and ready to use — no coating or prep needed. Color durability depends on exposure to UV and heat; shielding the hose from direct sunlight extends color life.
