Frequently Asked Questions
Do I need hose clamps to install this?
Yes. Clamps are not included — grab stainless steel hose clamps sized for 3.50" diameter to secure each end. Worm-gear clamps work fine for street cars; T-bolt clamps give you more clamping force if you're running high pressure.
Can I use this straight hose on a tight corner in my engine bay?
Not without bending it. This hose is designed as a straight section — if you need to route around tight angles, pair this with 90-degree or 45-degree silicone elbows sized to match the 3.50" bore.
Will this hose work as a replacement for my stock radiator hose?
If your factory hose is 3.50" diameter, this silicone version will fit the same connection points — but verify your hose routing and connection locations before ordering. Silicone handles higher temperatures than rubber, so it's a solid swap for track use or engine builds.
