Stepped silicone hose for smooth diameter transitions in coolant, vacuum, and boost lines. 3-ply construction handles heat and pressure spikes without collapse. Red compound resists ozone and UV degradation in engine bays.
Do I need clamps for this hose?
Yes. Use worm-gear or spring hose clamps sized for both the 3.00" and 4.00" ends — one at each diameter to seal properly. Clamps are sold separately.
Can I use this for boost lines on a turbo setup?
This hose handles light boost pressure, but confirm your system's PSI rating before install. For sustained high-boost applications, verify the 3-ply rating matches your turbo's spec sheet.
What's the length of this reducer?
Length not specified in the product data — measure your application before ordering to ensure it bridges your gap. Test-fit length against your intake tract or coolant routing before final clamping.
