Hybrid Racing T-Bolt Radiator Hose Clamps for 06-11 Civic Si

Hybrid Racing T-Bolt Radiator Hose Clamps - 2006-2011 Honda Civic Si

Swap out the tired factory spring clamps on your 2006-2011 Civic Si for the Hybrid Racing T-bolt radiator hose clamps. They give you a more secure, even clamping force than spring clamps, and they clean up the engine bay at the same time. The set is sized for this car and works with both OEM and Hybrid Racing silicone radiator hoses, so it's a simple upgrade that's both functional and good-looking.

Why T-Bolt Over Spring Clamps

Factory spring clamps are fine until they aren't, they lose tension over time and don't clamp as evenly, which is exactly how you end up with a slow weep at a hose connection. That's especially true on silicone hoses, where a spring clamp can let coolant seep past. A T-bolt clamp applies even, adjustable pressure all the way around the hose for a reliable seal that holds up to the heat and pressure of a hard-driven engine. You tighten it once and it stays put.

The Right Set For The Si

This set includes the correct sizes for the 06-11 Si's radiator hoses:

• 4x large T-bolt clamps, 37mm to 42mm
• 2x small T-bolt clamps, 31mm to 36mm

They fit both the OEM hoses and Hybrid Racing silicone radiator hoses, so they're a clean pairing with our Silicone Radiator Hose Kit if you're refreshing the cooling system at the same time.
