Vibrant Performance 3.0-ID x 3inch

When you're pushing your engine to its limits, your cooling system connections need to handle the heat—literally. Vibrant Performance's reinforced silicone couplers are engineered to survive the brutal conditions of high-boost, high-temperature environments where standard hoses fail. Built from hand-wrapped, 4-ply high-grade silicone, these couplers won't swell, crack, or burst when things get extreme, keeping your coolant flowing right where it needs to go.

This 3.0-inch ID coupler is rated to handle temperatures from -65°F all the way up to 500°F, giving you the thermal stability that serious builds demand. Whether you're running a supercharger, turbo setup, or just maxing out your cooling capacity, these couplers deliver the reliability you need without compromising flow or fitment.

Speed Tuned Motorsports customers know that cooling system failures end track days fast—these hose couplers are the upgrade that keeps your engine running strong lap after lap.
